I've been keeping cichlids for almost 10 years but have never tried any of the Lake Malawi species. I'm setting up some new tanks and am considering making one of them a mbuna tank. The tank dimensions (LxWxH) will either be 48x24x15 or 48x36x15. Any thoughts on which tank size is better for mbuna along with some stocking suggestions? Based on what's potentially available to me, I'm considering stocking with Metriaclima "Msobo" along with tropheops sp. red cheek and maybe some Iodotropheus sprengerae. Could I do three species and are these good options for a 4 foot tank?
