I have a 30 gallon tank that sitting as I have moved the fish from there into my larger tank. I was looking to make it a Tang. tank and include the following fish:
neolamprologus similis (4)
Black calvus (2-3)
lamprologus ocellatus (2-3)
Will this tank be too crowded and cause too much aggression/stress if i have the fish listed above together? I've read that the similis would probably be pushed around the most and I might want to leave them out. The tank has a hanging filter, heater to 76 F, pH about 8, sand substrate with snail shells and a unpolished conch shell for the bristlenose pleco currently the only resident in the tank. If 3 of the four might work I would like to try the similis, calvus, and caudo.
