Hi, my question is do you think that I could put a pair of brevis 3-4 yellow labs and maybe a colony of multies into a 29 gallon tank, obviously I'd have rocks and shells,
I would not mix these guys together. Any type of African of cichlid should be in a larger tank more like a 55g and housed with more Mbuna. Maybe getting rid of the yellow labs, picking either the multies or brevis and then housing some other fish you want around the one you choose.
