Why is my iridescent shark always hiding?

Answer by  Uvindu (35)

Maybe the other fishes in your tank are aggressive. If you have aggressive fishes they may be forcing your iridescent shark to hide. Iridescent sharks are not aggressive fish. So, they normally hide when they are in a tank which contains aggressive fish. So, you will have to take your iridescent shark to another tank or take the other fishes.

This all depends on what type of other fish you have in your tank. Iridescent sharks are not aggressive fish so if your other fish are aggressive that's your problem

Iridiscent sharks don't like bright light, they are also very sensitive to vibrations. Since they grow several feet long and need a very large tank they are poor aquarium residents. However you can try adding caves and reducing the light to make him more comfortable. Please do research their eventual size, though!

This could be due to the creature desiring a specific temperature in water. Water in and under objects are known to be cooler than the surrounding areas. This could also be an evolutionary trait in which the fish hide as a means to protect itself. Iridescent sharks have poor vision and may hide to avoid "stress" or attack.

You might have some other fish in the same tank that are aggresive or territorial. Maybe the other fish are forcing your shark to stay in hiding.
