Well- I purchased a small Raccoon Butterfly ( I think a Red Sea as color his colorings are beautiful ) a few weeks ago and am keeping him in my isolation tank. I am feeding him one rock at a time that has any atips or MoJo's on it. He eats them immediately, and I wait a day or two to change the rock out and supplement his diet with brine and other frozen foods. So far he will not eat any softies, ricodias , or acros (sps). He did begin to pick on my lobophilia (brain) after eating all the MoJo's off the sides of it he could find, so I had to take that coral out pretty quickly. He will definitely eat any Zoos or button polyps. I haven't tried other LPS (hammer,frogspawn, elegance) corals in my tank yet to determine if he will eat them or not before releasing the Raccoon in my 90 home show tank. All corals that are in danger of being eaten will be transfered to my office tank before I move the raccoon over form the isolation tank to the 90. I will keep the Raccoon until I have no more Mojos or atips for a while and find someone else that wishes to purchase him from me who has a FOWLR or will do what I did with him. I also have a torch (thanks -J ) if the raccoon fails to completely clear the tank of pests within a reasonable time frame. IF anyone is interested in the Raccoon when he is finished with his assigned duties at my place please contact me. I paid $60 for him ( he does eat brine and other frozen food) and I will only be asking the same price I paid from a fellow refer. I expect him to be available in about three weeks or so.
