my fish named nemo

[nemo20021]

My fish named nemo keeps killing other fish.He even killed his best friend.We got nemo and mator on the same day and he still killed the other one.He is a clown fish.Any Answers?

They are an aggressive species. Probably territorial issues.
Tank size?

Were the two clowns the same size??? This can be a problem as well. What species of clown do you have? As 2Quills asked, what tank size? A small tank can bring out more aggression.
