What are some good tankmates for a redhead cichlid? I'm getting one in today and he's gunna be solo and 4 inches. I have 2 1.5 inch jack Dempseys, 2 blood parrots around 3-4 inches, and a pleco that's about 7inches all in a 55 gallon. I like to grow my fish out and sell them but I don't want any blood shed in the tank. Out of experience, would it work?
