i recently setup a 77 gallon malawi tank containing 12- 2" kenyi and now im curious to know what other people think i should add next. for filtration i have a marineland c530 and an ac70. my thoughts are that i would do 12 demasoni but the females i think look to much alike then possibly johanni, or red top afra or cobue. let me hear your thoughs and ideas. in the end id like to have 3 different types if atall possible
