I am new to the reef part of the hobby, and would like some input. I have a tank that I have been told is a 156 gallon (6' bowfront) with about another 40 gal in the sump. I have a few pieces, (torch, 2 types gsp, baby blue chalice, pulsing xenia, mushrooms, and a random sps that I don't know what it is) and would like to know some other corals that are easy to keep, and look good. The fish I currently have; sargassum trigger, flame angel, 2 clarki clowns, 2 "nemo" clowns, a few chromis, naso tang and dwarf lion, and snails, crabs, cleaner shrimp... other fish I am considering: another tang (purple, black, WHITE...) mandarin goby, some small schooling fish (?) And very lastly, a yellow tang (wifes orders). Only thing is, I have always had predator tanks... so I would like some input.
