Very nice! Are all of those cichlids the kind that live in empty shells? I've been keeping fish for ages, but I have never kept cichlids, so I don't know much about them.
Not all of them are. The little ocellotus is a shell dweller. She is an adult and is only 1", the male is a little bigger. I have another shell dweller species that grows to just under 3", they sure are easy to catch. When you stick your hand in the tank they dive for a shell. cichlids are so fun.
