First is a red zebra (Metriaclima estherae), the second is an auratus (Melanochromis auratus) and the last is an OB zebra (Metriaclima estherae (OB)). The last is basically a color morph of the re zebra.

ok i have those 3 in with 1 yellow lab around the same size and a brichardi around the same size are these all compatible in a 55 gallon? if so should I be worried about lots of babies coming from some of these guys?
