Ok, so I have my new fishroomish thing set up, with 4 10g, 2 20longs, a 40 breeder, and a 5 gallon, all run off sponge filters. Im planning on breeding African cichlids. I plan to get either a group of peacocks or saulosi for the 40 (if possible would saulosi work in the 20 long?), some multies for a 10, a pair of either julidochromis or kribensis for the other 10. Any advice? will the saulosi work in the 20 long? if not, whats another African species that could work in the 20 long?
