If you’ve kept fish for any amount of time, you know the story: you look into your tank one day and you see it. The white spots. Maybe it’s only one or two on a single fish’s fin, or perhaps it’s coating every fish like they’ve been rolled in table salt. You have ich in your tank. Now what? Clarification: This post is referring to freshwater ich, marine ich is a different species which can be found in our separate post.

Understanding Ich (White Spot Disease)

Ichthyophthirius multifiliis, commonly known as ich or white spot disease, is an external parasite that attaches to your fish’s fins, body, and gills. It forms tiny white capsules (usually less than 1 mm in diameter) that feed on your fish until mature. Once matured, the parasite falls off, encapsulates itself on the tank substrate, and rapidly multiplies. Early detection and treatment are crucial for your fish’s recovery.

Ichthyophthirius multifiliis is a relatively large, single-celled ciliated protozoan. This disease is a major problem to freshwater aquarists and commercial fish producers worldwide. All species of freshwater fish are considered susceptible, and the parasite has been found in all areas of the world in both cultured and wild fish. Although large, these parasites do require a microscope to confirm them as a cause of the characteristic white spots that are often seen on the skin and fins of infected fish. The disease is highly contagious and spreads rapidly from one fish to another without the need for additional hosts (direct life cycle).

Identifying Ich in Your Freshwater Fish

Fish afflicted with ich appear as if sprinkled with salt, often showing tiny white spots on their fins first. Other symptoms include loss of appetite, rapid breathing, rubbing against surfaces, lethargy, and hiding behavior. Unlike stress-related symptoms, which affect fish uniformly, ich manifests with an increasing number of spots daily.

Can Humans Get Ich from Fish Tanks?

Rest assured, ich cannot infect humans. However, it’s crucial to wash your hands and arms thoroughly after handling aquarium water to prevent the spread of the parasite to other tanks. Avoid sharing equipment between aquariums, and disinfect tools with hot and chlorinated water, ensuring they dry completely before reuse.

The Ultimate Ich Treatment Plan

After extensive testing, I’ve found that Aquarium Solutions Ich-X has been particularly effective in my experience. However, there are numerous medications and treatment approaches available for ich. Here’s a step-by-step guide:

1. Confirm the Diagnosis: Ensure the disease is indeed ich and not a similar-looking ailment like stress-related symptoms or velvet.
2. Initial Dose: Administer Ich-X as directed—5 ml per 10 gallons of water. Wait 24 hours before proceeding.
3. Water Change and Redose: Perform a one-third water change and dose again at 5 ml per 10 gallons. Treat the total volume of the tank, not just the new water.
4. Repeat Daily: Continue the treatment every 24 hours until no ich spots are visible.
5. Extra Day: After the last spot disappears, treat for one additional day to catch any free-swimming protozoa.
6. Gradual Removal: Leave the medication in the water and remove it slowly through regular water changes.
7. Post-Treatment Care: Monitor for secondary infections due to the fish’s weakened state.

If no improvement is seen after five days, reassess the diagnosis as you might not be dealing with the ich parasite.

Treatment Upkeep

Once an outbreak of ich is detected, it’s crucial to initiate a treatment protocol immediately. Controlling this parasite can be challenging due to its complex life cycle, multiple protected stages, and high reproductive rate. The disease becomes especially severe in crowded tanks. Unlike many protozoans that reproduce by simple division, a single Ich parasite can generate hundreds of new parasites in one cycle. This makes early detection and treatment critical. The timing of treatment, influenced by water temperature, is also important and will be discussed further below.

Only the free-swimming theronts are susceptible to chemical treatment, meaning a single dose will only kill theronts that have emerged from the tomont cyst and not yet burrowed into the host fish’s skin or gills. A single treatment dose will not affect organisms that emerge after the chemical has broken down or been flushed from the system. Therefore, repeated treatments at appropriate intervals are necessary to continually kill the juvenile, infective theronts, preventing the infection from continuing. As more adult trophonts drop off the sick fish, encyst, and produce theronts, the ongoing chemical treatment will eliminate them in the water.

This process can be significantly enhanced by removing organic debris following treatment since the sticky cysts of the tomonts can attach to organic material. Cleaning this debris will help remove many cysts from the environment, further reducing the number of emergent theronts. When disposing of debris, ensure it is not discarded in a manner that could spread the parasites to a different tank or system. Remove any dead fish as soon as they are seen because mature trophonts will quickly abandon a dead fish and begin reproducing in the environment.

Alternative Treatments for Ich

An alternative to chemical treatments involves gradually increasing the temperature in your aquarium to 86 degrees Fahrenheit (30 degrees Celsius) over the course of about two weeks. This method accelerates the ich life cycle, reducing treatment times. However, it’s not suitable if your tank contains live plants, as they may not tolerate the higher temperatures well. Combine heat treatment with careful monitoring and follow-up to ensure the parasite is effectively eliminated. If Ich-X is unavailable, salt is a reliable alternative, especially for cichlids and goldfish. However, be cautious with catfish and loaches, as they can be sensitive to salinity changes.

Conclusion

There’s ongoing debate about whether ich is always present in aquariums. Regardless, maintain your tank as if it is. The disease typically strikes when fish are stressed or weakened. Ensure you quarantine new fish, maintain water quality, and avoid rapid parameter changes to prevent future outbreaks and you will be safe from dealing with these pesky protozoans!

Ever wondered how often you should change the water in your fish tank to keep your aquatic friends healthy and thriving? Water changes are crucial for maintaining a stable environment and ensuring your fish live long, happy lives. Let’s dive into the essentials of water change frequency and methods!

Why Are Water Changes Important?

Regular water changes help remove harmful substances like ammonia, nitrites, and nitrates that build up over time. They also replenish essential minerals and nutrients, keeping your aquarium’s water chemistry balanced. Clean water is vital for your fish’s health, preventing diseases and stress.

The Importance of Regular Water Changes and Filter Maintenance

Neglecting regular water changes and filter maintenance can lead to a buildup of harmful pathogens in your aquarium. This stagnant environment can foster diseases like fin rot and more severe conditions.

Fin Rot and Infections

When water quality deteriorates due to infrequent changes, the buildup of organic waste and bacteria can lead to fin rot. This bacterial infection starts with the degradation of the fish’s fins and can spread to the body, causing severe damage if not promptly addressed. Regular water changes help dilute harmful bacteria and reduce the risk of this disease.

Hole in the Head Disease

Another serious condition exacerbated by poor water quality is Hole in the Head disease, also known as Head and Lateral Line Erosion (HLLE). This disease primarily affects cichlids and other large freshwater fish. It manifests as pits or holes in the fish’s head and along the lateral line. Poor water quality, especially high levels of nitrates and phosphates, can compromise the fish’s immune system and lead to this debilitating condition. Regular water changes and maintaining good water quality are crucial in preventing and managing Hole in the Head disease.

By keeping up with water changes and maintaining your filter, you ensure a healthier environment for your fish, reducing the likelihood of these and other health issues.

Large Water Changes: The Benefits

Contrary to popular belief, large water changes of 80-90% can be beneficial, as long as the new water closely matches the chemistry of the old water, including temperature, pH, and other parameters. Large water changes can effectively remove accumulated nitrates, phosphates, pheromones, and other byproducts of daily life inside a fish tank. This method is especially useful for tanks with high stocking levels or for keeping water conditions pristine for sensitive fish like discus.

The Role of Plants in Water Quality

Heavily planted tanks can help reduce the frequency of water changes. Plants naturally absorb nitrates, which are a byproduct of fish waste and decaying food. By incorporating a variety of aquatic plants, you can create a more balanced and self-sustaining ecosystem. This not only benefits your fish by providing a cleaner environment but also reduces the workload on you as an aquarist.

Steps for Performing a Water Change

1. Prepare Fresh Water: Ensure the new water matches the temperature and parameters of your tank water. Use a water conditioner to remove chlorine and chloramines.
2. Clean the Tank: Before changing the water, gently clean the tank walls and decorations to remove algae.
3. Vacuum the Substrate: Use a gravel vacuum to remove debris and uneaten food from the substrate.
4. Remove Water: Using the gravel vacuum or a siphon, remove the appropriate amount of water.
5. Add Fresh Water: Slowly pour the prepared water back into the tank to avoid disturbing your fish.

Filthy Filters and Clear Water

A key principle in successful fish keeping is to maintain clean water while allowing your filter to collect beneficial bacteria. While good filtration keeps your water looking clear, it doesn’t remove all the harmful nitrates, phosphates, and other byproducts that accumulate over time. Regular water changes are essential to keep these levels in check.

Always remember, clean water contributes significantly to the health of your fish. Following a consistent schedule of water changes can lead to healthier, more vibrant fish that are able to grow to their full potential. Over time, water that is not changed can encourage unsightly algae growth and weaken your fish’s immune system. Simply make sure to adjust the frequency and volume of your water changes based on your tank’s specific needs, and you should be good to go!

Conclusion

Maintaining a regular water change schedule is essential for the health and happiness of your fish. By understanding your tank’s specific needs and adjusting your routine accordingly, you can create a thriving aquatic environment. Remember, consistency is key, and your fish will thank you for it!

Happy fishkeeping!

“Ever wondered what it takes to bring the mesmerizing beauty of a coral reef into your living room? Starting a saltwater tank setup requires more planning and investment compared to freshwater tanks, but it isn’t the rocket science people fear it may be either. Let’s dive in and learn what it takes!”

Introduction to Saltwater Aquariums

Saltwater aquariums let you bring a piece of the ocean into your home. They’re full of colorful fish, corals, and other marine life. Starting a saltwater aquarium can be a rewarding hobby, but you should know the costs and what to consider first.

Costs and Considerations

Starting and keeping a saltwater aquarium takes time and money. The cost of the tank, gear, and the fish can be high, from hundreds to thousands of dollars. You also need to think about ongoing costs for saltwater, supplements, and parts.

Saltwater fish and creatures are pricier than freshwater ones. Keeping your tank healthy means regular water changes and checking the water’s condition. It’s key to a successful saltwater aquarium.

Equipment is another part of the hobby that is more expensive than freshwater. Sumps, skimmers, auto water top-offs, refugiums, lighting and even the salt used for creating your saltwater will all factor into your expenses.

Before starting your saltwater aquarium journey, think about if you have the time, space, and money. Doing your homework and planning can make your aquarium experience better and more fun.

“Saltwater aquariums offer a unique and captivating viewing experience, with a diverse array of colorful fish, corals, and other marine life.”

Planning Your Saltwater Tank Setup

Setting up a saltwater tank requires careful thought about the tank’s size and material. For beginners, I suggest starting with a tank of 55-60 gallons. Nano reef tanks might look easy but they’re tricky because they’re sensitive to changes in water chemistry.

Choosing the Right Tank Size

The size of your saltwater tank affects how hard it is to keep it running well. Bigger tanks cost more at first but they’re more stable and can hold more marine life. Think about how much space you have, your budget, and your aquarium plans when picking a size.

Selecting a Tank Material

Tanks can be made of glass or acrylic. Glass tanks are simple to clean but might scratch easily. Acrylic tanks are lighter, less likely to break, and have strong seams but can scratch too. The stand and canopy you pick also matter for your tank’s look and how well it works. They need to be strong to hold the tank and its gear.

Choosing between glass or acrylic depends on what you like, your budget, and what your marine life needs. Think about the good and bad of each material to make a tank that works well and is fun to have.

Essential Equipment for a Saltwater Tank

Setting up a saltwater aquarium means picking the right gear. Key items include the filtration system and the lighting setup. Let’s look at what you need for these important parts.

Filtration Systems

“Maintaining a pristine environment is crucial for the well-being of marine life in your saltwater tank. While under-gravel filters, canister filters, and wet/dry trickle filters are common in freshwater setups, they may not be ideal for saltwater aquariums. Instead, consider investing in a sump system which integrates biological filtration using live rock and enhances efficiency with a protein skimmer. This approach ensures effective removal of harmful compounds and supports a thriving aquatic ecosystem. If a sump system isn’t feasible, focusing on a protein skimmer paired with live rock can still provide effective biological filtration in your saltwater aquarium.”

Choosing the right equipment depends on your tank size and the fish/inverts you keep. This ensures your saltwater aquarium stays healthy.

Lighting for Marine Environments

The lighting you pick depends on the marine life in your saltwater tank. For fish-only tanks, you don’t need special lighting. But, for reef tanks with corals, you’ll need strong lights for their survival.

Choosing the Best Coral Lights: Why PAR Matters

When selecting lighting for your reef tank, it’s crucial to focus on lights that offer the appropriate Photosynthetically Active Radiation (PAR) levels. PAR measures the intensity of light available for photosynthesis, which is essential for the health and growth of corals, and different corals have varying light requirements. SPS (Small Polyp Stony) corals generally need high PAR levels for optimal growth, while LPS (Large Polyp Stony) corals and Zoanthids prefer lower PAR. This is just a generalization, so be sure to choose lighting that accommodates the needs of your specific coral species to ensure a thriving reef ecosystem.

Top Coral Lights

1. LED Fixtures: Modern LED lights are popular for their energy efficiency and adjustable PAR levels. Brands like Radion XR30 and AI Hydra 32 offer customizable settings to cater to different coral needs.
2. T5 Fluorescent Lights: Known for their broad light spectrum, T5 lights like the ATI PowerModule provide high PAR and are excellent for corals that require intense lighting.
3. Metal Halide Lights: Although less common today, metal halide lights such as the AquaticLife 4-Lamp T5 HO are still favored for their strong PAR output, beneficial for deep tanks.

Choosing the right coral lights involves balancing PAR levels with your specific coral requirements to maintain a thriving reef ecosystem.

With the right saltwater aquarium filtration and lighting, you’re on your way to a thriving marine world. This will bring joy and wonder for years.

Cycling Your New Saltwater Tank

The nitrogen cycle is crucial for a successful tank. It lets beneficial bacteria grow and clean up waste like ammonia and nitrites. These can harm fish and other sea creatures. Cycling your tank takes 4 to 8 weeks and might need ammonia or nitrite supplements to start. Keep an eye on your water’s condition during this time to make sure it’s safe for your future pets.

Adding Live Rock and Substrate

Live rock and substrate are key in a saltwater aquarium. Live rock is crucial for your saltwater tank as it provides the primary source of biological filtration, hosting beneficial bacteria that break down harmful toxins and maintain a stable aquatic environment. In fact, it is arguably more important than any regular filter, given its role in sustaining long-term tank health. When setting up, arrange the live rock and substrate to improve water flow and look good. The substrate’s type and depth depend on your style and your livestock’s needs.

“Live rock and substrate are the foundation of a successful saltwater tank. They not only provide a natural environment for your marine life, but also help establish the crucial nitrogen cycle.”

By cycling your tank and arranging the live rock and substrate well, you’re on your way to a thriving saltwater aquarium.

Water Parameters and Testing

Keeping the right marine aquarium water parameters is key for your tank’s health and the life of its creatures. Regular saltwater aquarium testing helps keep the water quality high. As someone who loves saltwater aquariums, I’ve found that watching and adjusting things like pH, alkalinity, temperature, and salinity is crucial.

Getting a good test kit is a smart move. These kits let you check levels of important stuff like ammonia, nitrites, and nitrates fast and accurately. By keeping an eye on these marine aquarium water parameters, you can spot problems early and fix them before they get worse.

1. Check your tank’s pH often, keeping it between 8.1 and 8.4.
2. Watch the alkalinity levels, aiming for 8 to 12 dKH (degrees of carbonate hardness).
3. Keep the water temperature steady, between 72-82°F (22-28°C).
4. Pay attention to salinity, keeping it between 1.023-1.025 specific gravity.

Being careful with saltwater aquarium testing and fixing any issues quickly is the best way to maintain water quality in reef tanks. It might take some work, but it leads to a healthy, thriving saltwater aquarium that you’ll enjoy for years.

Stocking Your Saltwater Aquarium

Choosing the right fish for saltwater tanks is key to a thriving marine ecosystem. It’s important to match fish with others that get along and have similar needs. Always research the fish you want to add to your tank before bringing them home.

Adding fish to your tank should be done slowly. This lets the tank’s filters adjust to the new life. This keeps the water clean and safe for your marine tank.

Choosing Compatible Fish Species

When picking fish for your marine tank, think about these things:

• Temperament: Don’t mix aggressive fish with peaceful ones.
• Size: Make sure the fish won’t grow too big for your tank.
• Water needs: Your fish should like the tank’s water conditions.

Good Starting Options

1. Clownfish
   Hardy and vibrant, Clownfish adapt well to various conditions and thrive in tanks with live rock and hiding spots. Ideal for tanks of 20 gallons or larger.
2. Royal Gramma
   Known for their striking purple and yellow colors, Royal Grammas are resilient and peaceful. They do well in tanks of 20 gallons with plenty of hiding places.
3. Bangaii Cardinalfish
   Recognizable by their unique appearance and peaceful nature, Bangaii Cardinalfish adapt well to smaller tanks and are ideal for beginners. They prefer a tank of at least 30 gallons with ample hiding spots.

Introducing Invertebrates and Corals

Adding invertebrates for marine tanks and coral reef aquariums can make your tank more interesting. These creatures need special care and the right water conditions. Add them slowly and think about how they fit with your other tank friends. Also be aware of the need for dosing iron and other various elements to ensure species such as this cleaner shrimp can molt properly!

“Successful saltwater aquarium keeping is all about striking the right balance between art and science”

Pick fish and other sea creatures that live well together. Certain fish will prey upon your inverts and corals, and even vice versa!

Maintaining Your Saltwater Tank

Keeping your saltwater aquarium in top shape takes regular effort and attention. Two key aspects are regular water changes and controlling algae growth.

Routine Water Changes

Doing saltwater aquarium water changes is key. It helps replace vital nutrients and remove waste. How often and how much you change the water depends on your tank’s size, how many fish you have, and how much food they eat. Not changing the water enough can hurt the health of your fish and the water quality.

You might also need to dose supplements and check the water testing in your saltwater tank. This keeps your marine environment balanced and healthy.

Identifying and Treating Tank Diseases

Saltwater fish and other sea creatures can get sick for many reasons, like bad water quality, stress, or new additions. It’s important to know the signs of diseases like ich, velvet, or bacterial infections. This knowledge helps you treat them fast and stop the disease from spreading.

Having the right medicines and a quarantine plan ready is crucial. This way, sick fish can recover safely.

• Learn to identify the symptoms of common saltwater tank diseases
• Keep a quarantine tank ready to isolate and treat sick fish or invertebrates
• Research and have the appropriate medications available for disease treatment

Prevention: The Key to Keeping Your Fish Healthy

We can talk about treating diseases, but prevention is the cornerstone of maintaining a healthy aquarium. By proactively managing water quality, avoiding overstocking, and implementing quarantine procedures for new arrivals, you can significantly reduce the risk of disease outbreaks. Regular maintenance, including consistent water changes and filter cleaning, ensures that your tank environment remains stable and less hospitable to pathogens. Additionally, a well-balanced diet tailored to each species’ needs supports a strong immune system, further safeguarding your fish from illness. Taking these preventive measures helps you avoid the stress and expense of treating diseases and contributes to a thriving aquatic community.

Navigating the Ugly Phases of a New Saltwater Tank

Starting a new saltwater tank often involves dealing with some less-than-appealing phases. These may include cloudy water, algae blooms, or even a bit of a smell. These issues are typically part of the tank’s natural cycling process as beneficial bacteria establish themselves and water chemistry stabilizes. Patience is key during this period. Regular water testing, along with partial water changes, can help manage these problems. It’s also crucial to avoid overfeeding and to ensure proper filtration is in place. Though it may be tempting to rush or make drastic changes, allowing the tank to progress through these phases naturally will lead to a healthier, more stable environment for your marine life.

Scientific Name: Pterophyllum scalare

Common Names: Freshwater Angelfish, Common Angelfish

Appearance

Freshwater Angelfish are known for their unique, elegant appearance. They have a laterally compressed body, long triangular dorsal and anal fins, and a wide variety of color patterns and fin shapes. Common colorations include silver, black, marble, and gold. They can grow up to 6 inches in length and 8 inches in height, making them a striking centerpiece in any aquarium. Widespread breeding has led to a plethora of color morphs, providing a variety of options for aquarists.

Additionally, there are three main types of angelfish: Scalare, Leopoldi, and Altum. This profile focuses on the Scalare, the most common type, which includes all the colorful angelfish varieties.

---

Natural Habitat

Freshwater Angelfish are native to the slow-moving rivers and swamps of the Amazon Basin in South America, as well as a few other river basins. In the wild, they are found in large schools when they are young and become more solitary as they mature, though they still enjoy the company of others. They thrive in blackwater rivers, which are characterized by leaf and wood-strewn bottoms, tannins, shaded areas along the riverbanks, and abundant tetra fish, which are a natural part of their diet.

---

Tank Requirements

• Tank Size: Minimum of 29 gallons for a single angelfish, but larger tanks are recommended due to their territorial behavior. For multiple angelfish, a larger tank with a group of 4 to 6 is recommended to spread out any bullying.
• Substrate: Soft, sandy, or fine gravel substrate to mimic their natural habitat.
• Plants: Live plants such as Amazon swords, Java ferns, and Vallisneria are ideal. Floating plants can also provide shaded areas.
• Decor: Provide plenty of hiding spots with driftwood, rocks, and artificial caves.
• Filtration: Use a gentle filtration system to maintain clean water without creating strong currents.

---

Water Conditions

• Temperature: 75-82°F (24-28°C)
• pH: 6.5-7.5
• Hardness: 3-10 dGH
• Water Changes: Regular water changes (20-30% weekly) to maintain water quality.

Angelfish prefer slightly acidic to neutral water, but they are quite adaptable and can thrive in a wider range of parameters due to years of captive breeding.

---

Diet

Angelfish are omnivorous and require a varied diet for optimal health. In the wild, they feed on small insects, crustaceans, and plant matter. In captivity, their diet should include:

• High-quality flake or pellet food
• Frozen or live foods such as brine shrimp, bloodworms, and daphnia. Live foods especially can be enticing for young angelfish or individuals that are reluctant to eat
• Fresh vegetables like spinach and zucchini

Feed them small amounts 2-3 times a day to prevent overfeeding and maintain water quality.

---

Behavior and Compatibility

Angelfish are generally peaceful but can become territorial, especially during breeding. They do well in community tanks with similarly sized, non-aggressive fish. Suitable tank mates include:

• Larger tetras that are more than 3 in (like black skirt tetras and lemon tetras)
• Corydoras catfish
• Other Peaceful South American Cichlids
• Bristlenose plecos

Avoid housing them with very small fish or fin-nippers like tiger barbs.

---

Breeding

Breeding angelfish can be a rewarding experience. They form monogamous pairs and exhibit excellent parental care. To breed them successfully:

1. Pair Selection: Start with a group of 6-8 juveniles and allow them to pair off naturally.
2. Breeding Tank: Set up a separate breeding tank with a flat surface (like a slate or broad leaf) for them to lay eggs.
3. Water Conditions: Maintain the temperature around 80-82°F and keep the water clean.
4. Egg Care: The parents will clean the chosen surface and lay hundreds of eggs. Both parents guard and fan the eggs to ensure proper oxygenation.

Once the eggs hatch, the parents continue to care for the fry, moving them to different locations and protecting them from potential threats.

The best bet for breeding is to buy a group of 4 to 6 and see which ones eventually pair up.

Health and Disease

Freshwater Angelfish are generally hardy but can be susceptible to common freshwater fish diseases such as:

• Ich (white spot disease)
• Fin rot
• Bacterial infections
• Parasites

Maintaining optimal water quality, a balanced diet, and avoiding stress can help prevent these issues. Quarantine new fish before adding them to the main tank to reduce the risk of introducing diseases.

With their stunning appearance and engaging behavior, Freshwater Angelfish can be a delightful addition to any aquarium. By providing the right conditions and care, you can enjoy the beauty and elegance of these fish for many years.

Starting a freshwater aquarium is an exciting venture, but choosing the right fish is crucial to the longterm enjoyment of your tank, especially if you’re a beginner. I remember the first time I walked into a fish store, ready to get my first fish. The seemingly endless options of colorful, unique, and fascinating fish were overwhelming. I wanted to take them all home! But I soon learned that some fish, although popular, can present significant challenges for the new aquarist. Here’s my take on the top five worst beginner freshwater aquarium fish that are extremely common, and some better alternatives to consider.

1. Common Plecostomus (Hypostomus plecostomus)

Why They’re Popular: Commonly known as “plecos,” these algae-eating fish are often recommended by your local LFS or pet store to unsuspecting buyers for their ability to keep tanks “clean”. Another thing to be aware of is many plecos are misidentified at the fish store, meaning you need to really know the physical traits of the species you want, or you may end up with the wrong specimen!

Challenges:

• Size: Common plecos have the ability to grow up to 18 inches, which requires a much larger tank than most beginners tend to have. In order to thrive at full size, they require at least a 200-gallon tank in the 6-foot-long dimension range. Ideally, a small pond or pool is the best habitat for these large armored catfish once fully grown.
• Diet: Needing more than just algae to thrive, this particular species, Hypostomus plecostomus, is omnivorous, requiring a varied diet including vegetables and specialized pellets.
• Tank Conditions: They produce a significant amount of waste, necessitating robust filtration and regular water changes.
• Algae Control: Here is the main caveat, it is not even guaranteed that your plecos will eat the tank’s algae and keep your aquarium clean. Even if they do eat your algae, their high waste production can lead to elevated nitrate levels, and more nitrates can equal more algae. This means you’ll likely end up facing the same algae issue you were trying to solve in the first place.
• Growth Rate: The only saving grace of the common pleco is its somewhat slower growth rate compared to other large-sized fish. Even then, you still end up with a monster-sized fish in a matter of a few years.

Alternative: Consider smaller algae-eaters like Otocinclus or Amano shrimp, which are easier to manage in smaller tanks. There are also quite a few species of pleco that are smaller and better suited for home aquaria, such as the Bristlenose Pleco or Clown Pleco.

2. Angelfish (Pterophyllum scalare)

Why They’re Popular: Angelfish are admired for their graceful appearance and unique shape, making them a visually appealing choice.

A Juvenile Altum Angelfish

Challenges:

• Unpredictable Behavior: Contrary to their seemingly docile looks, angelfish can be very unpredictable in their behavior, often becoming aggressive and territorial with different fish, meaning that tankmates have to be carefully thought out.
• Fin Nipping: Due to their size and elongated fins, they can be prone to fin nipping. This means quick and feisty or territorial fish should be avoided.
• Small Fish: Very small fish are not a good idea as they can be eaten when angelfish reach their maximum size of around 5 to 6 inches in height.
• Water Quality: Although they are hardier now as generations have been bred to live in home aquaria, they still need very good water parameters to grow and reach their full potential without stunting.
• Tank Size: The smallest tank size an angelfish should be in is 29 gallons for 1 fully grown adult. If you want a decent amount of tankmates or other angels, a 55 or 75-gallon tank is recommended.

Alternative: Consider Pearl Gouramis or Rainbowfish, which offer beautiful colors and more predictable behavior, making them suitable for community tanks.

3. Oscar Fish (Astronotus ocellatus)

Why They’re Popular: Oscars are known for their intelligence, intricate patterns, and interactive behavior, often known as the water dogs of the fish world., they They are also popular due to the various new morphs available in the hobby, such as the Bumblebee Oscar and the Long Fin variant.

Challenges:

• Size and Growth Rate: Oscars grow rapidly, reaching up to 12-14 inches, and need a minimum 75-gallon tank. In order to add any fish or a second Oscar, you will need at least 125 gallons.
• Aggression and Territoriality: Although Oscars are not as aggressive as one might think, they can still become territorial as they age and will prey on tank mates small enough to fit in their mouths. The main challenge is keeping an Oscar in a community tank. Smaller fish can be eaten, and while larger fish might be suitable, you’ll need a larger tank, often in the 150-plus gallon range. The most ideal yet often underutilized option is to keep an Oscar by itself in a 75-gallon tank.
• Messy Eaters: Oscars are messy eaters, which adds to filtration challenges. If filtration is not sufficient, Oscars can be prone to Hole in the Head disease.
• Diet: They have a voracious appetite and require a varied diet, leading to increased waste and higher maintenance. Experienced keepers usually have to manage how often they feed them as overfeeding is easily accomplished with these fish.

Alternative: Consider the Chocolate Cichlid, which is less temperamental and slightly smaller. Other smaller cichlids like Keyhole Cichlids or the Blue Acara are also great alternatives for community tanks.

4. Bala Shark (Balantiocheilos melanopterus)

Why They’re Popular: Bala sharks are striking with their sleek, shiny bodies and active swimming behavior, making them a captivating addition to any tank.

Challenges:

• Size: Bala sharks can grow up to 14 inches! Although the more common size in home aquaria is around 8-10 inches. The main issue here for novice aquarists is that Bala sharks thrive in groups, and when you couple this with their active behavior and large size, you are looking at providing them with tanks of 200 plus gallons and on to fully satisfy their needs. Most people just simply do not have the space to keep them!
• Schooling Fish: They thrive in groups, so a beginner would need to keep multiple Bala sharks, further increasing the required tank size. At least 3 would be the minimum and 6 plus would be the ideal!

• Jumpers: Known for jumping out of tanks, they require secure lids to prevent escapes. Regular glass tops will not work unless fastened as these fish can generate a decent amount of power and air time when spooked.

Alternative: Try Denison Barbs, another type of cyprinid as well and add a pop of color. They are more suitable for standard beginner tanks.

5. Comet Goldfish (Carassius auratus)

Why They’re Popular: Often seen as the quintessential beginner fish, comets are as hardy as they come and have a long lifespan.

Challenges:

• Size and Space: Comet goldfish can grow up to 12 inches and produce a lot of waste, needing large tanks (at least 55 gallons) or outdoor ponds. A good rule of thumb is about 50 gallons of water per comet goldfish.
• Temperature Requirements: They prefer cooler water, making it challenging to keep them with other common tropical fish. These fish are best suited for tanks or habitats dedicated to cold water species, typically alongside other goldfish.
• Waste Production: Goldfish produce copious amounts of waste compared to other fish their size, meaning heavy filtration is a must.
• Longevity: With proper care, they can on average live for over a decade, which may be a longer commitment than some beginners are prepared for. The oldest known goldfish, named Tish, lived to be a whopping 43 years old!

Alternative: Fancy goldfish varieties like Red Ryukins are more manageable in size and have similar care requirements. Comet goldfish, unlike their fancy counterparts, thrive better in outdoor ponds or large stock tanks due to their larger size and cooler water needs.

Recap

Starting a freshwater aquarium is a rewarding hobby, but it’s essential to choose the right fish, especially as a beginner. Here’s a quick analysis of the challenges each of these popular fish present:

• Common Plecostomus: While they can help with algae control, their large size and waste production make them impractical for most home aquariums. Consider smaller pleco species or alternative algae-eaters.
• Angelfish: Their beauty is offset by their unpredictable behavior, aggression, and need for specific tank conditions. They can also prey on smaller fish and can fight amongst each other. Opt for more peaceful community fish like Pearl Gouramis or Rainbowfish.
• Oscar Fish: Their intelligence and personality are appealing, but their size and territorial nature require more experienced care. Adding other fish or a second Oscar necessitates a tank of at least 125 gallons, and community tanks require 200-plus gallon setups. Smaller, less aggressive cichlids like the Chocolate Cichlid, Keyhole Cichlid, or Blue Acara are better choices if looking for something similar.
• Bala Shark: Impressive swimmers, but their size and need for large groups and tanks make them unsuitable for beginners. Smaller schooling fish like Denison Barbs are a more manageable option.
• Comet Goldfish: Hardy and long-lived, but their size, cooler water requirements, and waste production pose challenges. Fancy goldfish varieties like the fancy goldfish are a more practical alternative for new aquarists.

Conclusion

By choosing more suitable alternatives, new aquarists can enjoy a more successful and rewarding aquarium experience. Remember, research and planning are key to a thriving aquarium, so always consider the specific needs of any fish before bringing them home. Happy fishkeeping!
