Columbian Shark

[Joeyt66]

I have a Columbian shark which is very small yet he seems to have lost most of his spunk, the only time he swims around he is doing a spin in the water. Ive only had him a week and the other one i got died already what could be wrong with him.(water test are fine) Maybe i should try putting him in my hospital tank with some salt in the water , would that be ok ?

Arnt they a Brackish Water fish? If so you need brackish water not fresh water ADD SALT!

As they get older, they migrate to brackish water in the wild. Eggs are laid in FW
