I have some multis and 1 calvus in a 40 breeder. Can I add 2 more calvus? Or Would I be better off going with a different species and if so what species and how many? I'd like to have some rock dwellers like julidochromis, shell dwellers and an open water/mid level fish aswell.

I'd say not enough space to add another species. You could probably try to pair your Calvus off but other than that It'd be tough to fit much more in. You'd really want a 55 or 75 gallon to add Cyps to the tank for open water.
