He does not touch the SPS, LPS, or my maxima clam. We had some pink and white sponge growing on the bottom of some of the rock, he cleaned that up other than that all he touches is the pellets, mysis, nori, flake, anything I feed them pretty much. He is around three inches. Again, I do consider myself very fortunate with him, other people may say the opposite. Many of the other regals I have seen were in the five inch range, maybe cause my guy was so small he was easier to get onto prepared food and leaves everything else alone, for now at least
