I have a 120 reef setup. My current fish are 2 blue damsels, 1 Maroon Clown, 1 Lear tail Angel, 1 Kole tang and 1 Copper band I would like to add some cleaner shrimp soon.. I like the look of the wrasses but from what I read they need sand and a cover on the tank. Are there any that don't require a sand bed and aren't jumpers?
