In my 65g Malawi tank, I have yellow labs, socolofi, cobalt zebras, rusties, and melanochromis cyanorhabdus (it's a bit overstocked, LOL). I'm considering getting rid of the cobalt zebras, and trimming down the number of yellow labs, and maybe getting some acei, so I get some activity in the top 1/3 of the tank. But the mix I have now is nice, I've got yellow, light blue, dark blue and black, and purple/brown. Oh, and I had four jewel cichlids, but I moved the pair that spawned and the other two that are left don't appear to be pairing up, so they're not very colored up.
