cow fish

If you read previous threads on them it boils down to is the tank large enough? Is it housed with proper tanks mates that won't out compete it for food? And the tank size thing again. They get extremely large, especially with their horns full grown. They are poor swimmers at best and won't do well with high flow or aggressive eaters like tangs and angels. They have a personality much like a puppy and can make great fish provided they are housed properly with proper husbandry. They can release toxin from their skin if stressed or they die which can negatively effect tankmates if left unchecked. Good tankmates are large filefish,other boxfish, pipefish would probably make good tankmates since they enjoy low flow and none aggressive tankmates too. Don't quote me on the pipefish I'm just running thru fish that could fit the bill.
 
It is a amazing fish and I'm a big fan of cow and box fish. I have had quite a few of them in the past, and currently own a male blue box. They indeed can nuke the whole fish population if frightened and enough toxin is released. Make sure to keep your carbon fresh at all times. It loves high current flows but need spots within your tank to have low steady flow to stabilize itself when it gets itself in trouble. It will spit water out of the tank when it settles down in your tank, and that's their sign of begging for food. It's quite cute but troublesome at the same time bc all the water on the floor. I had one cow fish that loved eating soft corals like leather. Strange I know but it just couldn't resist the slimy soft tissue and dashed it's clumsy body over the length of the tank and attacked the leather coral.
