Good question about what species
Been doing research for more than a month and have gone from Peacock to Haps to Mbuna to Peacock/Haps to Mixed to maybe just keeping my lonely Oscar :-? :-? :-? .
btw, nice rocks F8LBITEva any problems with keeping the gavel clean under those rocks?
I find that most do mbuna once and always go towards other African cichilids, Malawi, Tanganyikan or whatever... Mbuna are so boisterous that it gets kind of annoying after a while. They are very very very hardy, though, breed readily and are very colorful. So, if you're looking for those things, with little 'brains', then go for them.
