thanks...my clarki and common clown get along fine but i have heard of people having bother mixing some species of clowns....a guy i know tried to mix a maroon and a tomato clown together and it didnt work..the tomato nearly killed his maroon clown so he traded the tomato in to his LFS.Nice tank.
Sorry but i don't know much about SW tanks but i didn't thing you could mix different clown fish in the same tank?
