Iridescent Shark

The iridescent shark, also known as the iridescent catfish (Pangasianodon hypophthalmus), is a freshwater fish that is often seen in the aquarium trade. However, there are important considerations to keep in mind if you’re thinking about keeping iridescent sharks in your aquarium:

Iridescent sharks can grow quite large, often reaching up to 3 feet (90 centimeters) in length in captivity. As such, they require a substantial tank, typically at least 100 gallons for a single fish and even larger for multiple fish.

Iridescent sharks are active swimmers, and they need a spacious tank with plenty of swimming space. The tank should have good filtration and a strong water flow because they come from fast-flowing rivers in Southeast Asia.

Iridescent sharks are social fish and do best when kept in groups of three or more. However, due to their size, tankmates need to be carefully chosen to avoid aggressive or territorial behavior. Peaceful, large tankmates that can handle the same water conditions are the best choice.

They are omnivores and primarily feed on small fish, crustaceans, and plant matter in the wild. In captivity, they accept a wide variety of foods, including commercial pellets, live or frozen foods like fish or shrimp, and some plant matter.

Iridescent sharks are sensitive to water quality. Maintaining proper water parameters, including temperature, pH, and ammonia/nitrite levels, is crucial for their health

Iridescent sharks can live for 15-20 years or more when provided with suitable care and conditions.

Ensure that you’re adhering to local laws and regulations, as the sale and ownership of iridescent sharks may be restricted or prohibited in some areas.

Be aware that as these fish grow, they may quickly outgrow smaller tanks, and rehoming them can be challenging. It’s better to start with an appropriately sized tank from the beginning.

Before adding iridescent sharks to your aquarium, it’s essential to do thorough research and consider whether you have the necessary resources, space, and commitment to provide them with the appropriate care and conditions throughout their potentially long lifespan. If you’re unsure, it may be a better idea to explore other fish species that are better suited to your available tank size and experience level.
