That tank is way too small. Good to hear you are upgrading. Red zebras and auratus get to be larger than the lab. You are going to need at least a 55 gallon tank. These fish need the 4' length to establish enough territort. You also have way too many species for a 3o gallon tank. If you only want to get a 30 gallon then rehome the fish you have and get some dwarf mbuna instead. Ps saulos do well in a tank that size.
