Im planning on turning my 180 into a cichlid tank. The footprint is 6x2x2. As for filtration I am using a FX5, and an XP4. How many cichlids could I put in there? Right now I have 5 yellow labs, 4 rusties, 2 red zebras, 5 colbolt blue zebras in a 55 gallon. I also have about 25 demasonis fry in a grow out tank. With this information, how many more fish do you think I could put in there? Also what else would be a nice addition to this tank? Thanks for your help.
