My favourite fish is a keyhole cichlid and I just lost my little guy so I was elated when I saw they were selling very small keyholes at my LFS. I bought one and I have had the fish for about 10 days now and it's growing like crazy - the only problem is that there is no way it's a keyhole. It was very hard to tell when the fish was small but as it has grown its colouring is way off. I"m concerned because I have small tanks and I can't keep larger fish. I'm worried that it's a saddle cichlid which is 8 inches, far larger than any fish I want to keep and certainly not in my 20 gallon. This has never happened to me before - just wondering if anyone else has come across it. How did the store compensate you?
