Agreed i do not see any brichardi's as well, all mbuna mostly zebras, yellow labs and maybe a socolofi..
Same as most Mbunas. They're still vegetarians and need lots of vegetable and algae in their diet. You'd want to stock them pretty heavily. Coler's stocking advice still fits well for your setup. The fish you have do not appear to be the more aggressive of the Mbuna family, but sets of 3 with 1 male to 2-3 females would still be your best bet.
