Fish may die

My clown fish is very discolored, fins look like their being chewed, and hides under rocks. I have 3 clowns and 2 of them(Male, Female) cause a lot of stress to the other one which may be the problem but idk? any suggestions on which one to pull?

 

Pull the one that is being attacked. You can only have 2 clowns per tank.

 

2 of them r probably paired; take one out

 

Yes you need to seperate the clownfish and remove the most injuried to a seperate tank.

Good luck.

 

will the same thing happen when i get different fish

 

no, only with clowns will this happen.

 

Not really true. There is always a risk of aggression towards other fish or newly added fish. Many times it's not an issue. It mainly depends on each fish's temperment, but can also be affected by tank size, amount of rock in the tank and species. That's one reason why it's so important to carefully plan your stocking list.
