I have a 75 gallon tank. I posted similar topic before but was wrong about the fish I had in it. I am wanting a mixed tank with males and females. Right now I have 2 male c. Afra of some sort, 1m. Yellow lab,1p.socofolio not sure of the sex, 1 yellow tail acei female I think. 2 m.Estherae (cherry red zebras)I think 1m& 1f. And 1m p.crabro.he's gonna go. Everyone says stick to 4 species with a 1m to 4f ratio are there any of these that I should have better luck with? Suggestions please.
