Colombian Catshark in a 125

[BichirAddict]

Could a Colombian catshark be alright in a 125 with a senegal bichir,tiger oscar,bala shark,and maybe a tiretrack eel or is it overstocked. How much salt do I add to the tank when introducing the catshark.

Columbian Sharks need Brackish/Salt water.

The amount of salt you would need would kill everything else in your tank.
