How can I tell the differece between a Ram and a Cupid Cichlid? I have 2 and can't tell what they are? They look exactly the same but aren't getting along at all. In my 29g I also have a 1 maybe 2 Cribs. One crib is healthy and happy the other one is smaller and flat refuses to ever come out? I also have 1 brichardi that one store says will be mean and the other says is peaceful? Seems to be ok likes to hide in cave. I also have a small light blue fish that I have no idea what he is!? Right now he is smaller than all the other fish, but he is a total pig! I don't feed all the time but he looks like he is eating all the time and whenever I do feed anyone else his belly gets huge! I don't see any stripes on him, just small and light blue. Any guesses? I added 3 green tiger barbs yesterday and they are doing fine, not getting bothered or bothering anyone. THe biggest problem is the 2 rams or whatever they are, they have locked lips a couple times. I really hate not knowing exactly what I have! Anyone with help out there?
