I have a maroon clown and personally think they are the nicest looking clownfish. I second the comments that you cannot mix different types of clowns in the same tank but would also caution you against getting a maroon even if it was the only clown that you had.
Man, they are an ignorant fish!
I don't mind in my tank because the other fish is a Scott's Damsel and the two of them have reached a mutual agreement; however, it really limits any future fish selection. I'm sure that any peaceful fish would get bullied to death. JME.
