Several months ago I purchased 2 lightning maroon clownfish. I made the mistake of buying them at the same size. Eventually one that wasn't doing so well due to fighting I believe, then disappeared( I think he died then was wiped out by cuc) I am now looking for a new clownfish to go with my lightning maroon. Do I have to get a lightning maroon to go along or can I put any maroon clown with him and be fine. Also should my new clown fish be bigger or smaller than the fish that's been in my display tank?
