Hello have a 55 gallon i am going to set up in a month or so and cycle. I would like cichlids but do not want a real agressive tank. Size of cichlids i would like, would be from 4-6 inches 10-15 fish. I will be running a penn cascade 1000 canister 265 gph with 3 bio trays. Also a marineland penguin 350 filter has 2 bio wheels. Plus 1-2 powerheads in a ugj system. I would like to have a mix of colors, at least 3. Dont really want to deal with Fry, so dont need female mix really unless i have to then, i can try to sell them are give them to the LFS. Not really sure what species to go with just want a nice color peacefull and fun looking tank. It will have Big river rocks about mid way up the tank and a 3D background with sum caves in it possible. With black sand as the substrate. Any info are suggestions would be great. Going to order cichlids from live fish direct.
