Do you mean African vs. New World? You probably have African. If I understand your question correctly, you probably have a couple of different species of mbuna (rock dwellers) form Lake Malawi. That is my best guess based on the colors you mentioned and the fact that they were inexpensive in a big chain store. Blue with yellow fins is likely Pseudotropheus acei. Yellow has several possibilities, Labidichromis caeruleus (may not be spelling it right) would be my first guess.Holy_G said:I bought two cichlids at petco. A yellow one and a blue one with yellow fins, could some one tell me from what group they come? I understand there are two kinds of setup for cichlids. I bought this ones because they are cheap and I want to learn to keep them and breed them before I go into empeors cichlids.
