I up graded my tank from a 29 to a 55 and I would like some opnions on stocking it with a few more fish. Rite now I have a engineer gobie, watchman pistol shrimp pair, and a pepperment cleaner shrimp. I would like to add a yellow tang, flame angle, royal gamma, and maybe some kind of clown. I've also thought of adding a lawnmower blenny to help with alge. Any info or suggestions would be great
