Keeping shark fish in an aquarium can be an incredibly rewarding experience. These unique and fascinating creatures add an exotic touch to any tank setup.
However, many aquarium hobbyists find themselves struggling to care for their shark fish properly.
If you’re having difficulties, don’t worry—you’re not alone! In this comprehensive guide, we’ll explore seven common reasons why aquarists face challenges with their aquarium shark fish and provide practical solutions to help you overcome these obstacles.
1. Inadequate Tank Size
An improper tank is one of the most typical causes of problems with aquarium shark fish. For them to thrive, these energetic swimmers need lots of room.
In captivity, the majority of sharkfish species grow to amazing lengths of over three feet (0.9 meters).
Too little of a tank can cause several problems, including aggressive behavior, stunted growth, and increased stress.
Solution: Provide a Spacious Tank
Purchasing a tank large enough to fit your adult sharkfish is important for their health and well-being.
For smaller species, such as the rainbow or red-tailed black shark, you should generally strive for a tank that can hold at least 180 gallons (680 liters).
Larger species, such as the bala shark or iridescent shark, might need tanks that hold at least 300 gallons (1,135 liters).
2. Improper Water Parameters
Sharkfish require stable and suitable water conditions since they are sensitive to changes in the quality of the water.
When their ideal circumstances are not met, stress, weakened immune systems, and even disease outbreaks might result.
Solution: Monitor and Adjust Water Parameters Regularly
Make sure the following parameters are within the acceptable range for the particular kind of shark fish you have by usually testing the water in your aquarium:
- Temperature: The majority of shark fish prefer 72°F to 82°F, or 22°C to 28°C.
- pH: 6.5 to 7.5 is an excellent, slightly acidic to neutral pH range.
- Ammonia and nitrite: 0 parts per million, or ppm, should be maintained.
- Nitrate: Aim for nitrate levels below 20 ppm.
Regularly do 20–30% partial water changes, and use a high-quality dechlorinator to rid the freshwater of dangerous chlorine and chloramines.
3. Lack of Appropriate Tankmates
Shark fish, particularly those kept with unsuitable tankmates, tend to be hostile and territorial. The health and well-being of your shark fish may suffer from inappropriate tank mates, which can cause continual stress, fin nipping, and even physical fights.
Solution: Choose Suitable Tankmates Carefully
Taking your shark fish’s size, activity level, and temperament seriously is important when choosing tankmates. Here are a few broad recommendations:
- Avoid species that bite on fins, like serpae tetras and tiger barbs.
- Select calm, comparable-sized fish, such as rainbowfish, large tetras, or danios.
- To reduce territorial aggression, provide plenty of hiding places and divide lines of sight.
- An established aquarium can benefit from the progressive introduction of new fish.
Furthermore, try not to overcrowd the tank because this might worsen aggressive behavior and result in unclean water.
4. Insufficient Swimming Space
Sharkfish need a lot of horizontal swimming room because they are vigorous swimmers. Restricting them to a small or overly decorated tank can cause tension, fatigue, and even physical harm from decorations and tank walls slamming against them.
Solution: Provide a Long, Open Swimming Area
When arranging your shark aquarium, give more weight to the horizontal area than the vertical space. The length-to-width ratio of the tank should be at least 3:1 or higher.
Steer clear of packing the tank too full with ornaments since this may restrict the fish’s swimming space.
Instead, leave a few spaces open for unimpeded swimming, but don’t forget to leave enough room for hiding places and visual breaks.
5. Unsuitable Diet
Due to their omnivorous nature, shark fish need a diverse and wholesome diet to flourish. An unbalanced or insufficient diet can cause developmental delays, health problems, and nutritional deficiencies.
Solution: Provide a Balanced, Varied Diet
Provide a mix of premium flakes or pellets, frozen or live foods, and occasionally vegetable matter to satisfy your shark fish’s nutritional needs. This is a recommended feeding schedule:
- Staple Diet: Premium pellets or flakes designed for fish that eat a wide variety of foods.
- Protein sources: foods like brine shrimp, bloodworms, or daphnia that have been freeze-dried or frozen.
- Vegetable Matter: Once or twice a week, blanch cucumber, zucchini, or spinach.
Because shark fish are frequently grazers, their diet provides several little meals throughout the day.
Stay clear of overfeeding, which may result in water that is polluted and other health problems.
6. Lack of Hiding Spots
Since sharkfish are naturally shy, they can get uncomfortable in places where there aren’t enough hiding places or visual barriers.
Their immune systems may be weakened by this stress, leaving them more at risk for illnesses and other health problems.
Solution: Create a Naturalistic Environment
Give your shark fish tank lots of hiding places and visual breaks. You can do this with real or artificial plants, driftwood, rocks, and caves.
To make your shark fish feel safe and at ease, arrange these parts such that they create several hiding places and break the line of sight.
7. Incompatible Tank Setup
When it comes to tank design and decor, sharkfish have certain tastes. Stress, hostility, and even physical harm might result from an unsuitable arrangement.
Solution: Tailor the Tank Setup to Shark Fish Needs
Solution: Tailor the Tank Setup to Shark Fish Needs:
- Substrate: Opt for a fine, smooth substrate like sand or small gravel to prevent injury to the sharkfish’s sensitive barbels and mouths.
- Lighting: Because sharkfish prefer darker environments, use muted lighting. Steer clear of direct, bright lighting.
- Water Flow: Avoid strong currents that could stress the fish, but make sure the water flow is moderate enough to replicate their native riverine environments.
- Live Plants: For extra cover and oxygenation, use tough, low-light plants like cryptocoryne species, anubias, or Java fern.

FAQ
Which shark fish is best for aquariums?
Smaller shark species, such as the bamboo shark and coral cat shark, are excellent choices for home aquariums. These resilient bottom-dwellers don’t go much bigger than three feet and don’t show any territorial aggression. You must do thorough research on their care needs because they demand a large swimming area and particular water conditions to flourish.
Do aquarium sharks eat other fish?
Shark species are generally kept in aquariums, and if given the chance, they will consume smaller fish. It’s important to provide your tank mates plenty of room and hiding places, and to pick them wisely. Certain shark species can live together in peace with the right safeguards, but careful observation is required to prevent fish losses.
