I have a 29gallon tank with 1 false perc, 1 green chromis, 1 lawnmower blenny, mushrooms, torch coral, 1 cleaner shrimp, 1 peppermint shrimp, sand sifting sea star and a golden conch. Anyone have any recommendations??? I would like an angel or something to really show off the tank. I know angels are harder to keep and sometimes not reef safe. I want something with nice colors...
