I have had one over the past few years, he is huge. I hope you are referring to the lunare wrasse! Mine is about 7 or 8 inches long as is a pig. Very easy fish to take care of and adds a lot of color to a FOWLR tank. They do not eat coral but if you have any crustaceans, consider them lunch! Lives eating frozen prawn, actually frozen anything. I think that I could feed mine frozen hotdogs and he would eat it! They are a very active fish and he tends to make sure everyone is in check! HTH
