I would like to set up a 55 gallon (or something similar) cichlid tank. I've never kept cichlids before, and I'm still researching them. I would like to keep some species from Lake Malawi; I especially like electric yellow labs, Johanni, Kenyi, and Demason's cichlids. I have no clue if these species are compatable, or if they can be housed together in a 55 gallon. I know they're aggresive... How would they do together? Is it at all possible to keep these guys in the same tank, and would they be crowded in a 55? My water has a very high pH, so the cichlids would like it much more than my other tropicals. Any suggestions on these species (or any dwarf cichlids that may work out), and what they are and aren't compatable with, would be greatly appreciated!!
