Good God! Don't you have world war 3 with that many at feeding time? just kidding. No, my tank is a forty gallon 36" thing. After much head pounding, I think I'm just going to get a single male Pseudotropheus demasoni. If I keep overthinking, I'll have an empty tank forever. So, get food, order the fish, do a complete water change the day before the fish arrive and take it from there.
I really appreciate all your help. When this started, I wanted a ten gallon!
