I know that I don't even have my tank set up yet but I'm a dreamer. I really like the cleaner crew (inverts) like; Urchins, Starfish, snails, shrimps, crabs, claims, etc... What would be the best set up of these. The tank is a 72 bow front. I plain to have a FOWLR with about 70-75 pounds of live rock. I would like to have a lot or as much as possible of these little things.
