My LFS ordered some Cockatoo Cichlids for me. They got three males in a few days ago, and might be able to get in some females next week. They're holding the males right now to make sure that they are healthy, and so that they'll color up once they get calmed down. How to choose the best ones? I've never had any Cichlids before, and was wondering about their behavior. So how to tell if a male is the best one? Is it something to do with how they act? Their fin color or length?
