nacl freak-- Thanks. The fox coral is not really thriving right now. It is not dying or anything like that, but it is not growing much either. I can't find a spot in the tank that has low enough flow for it, but that is why I am gathering equipment to set up a 50 breeder as an SPS tank. Then I will lower the flow in the 75 and it will primarily be a lps reef. Hopefully that will help the fox coral out.
nycbob-- I have had the foxface for over a year and he has been a model reef citizen. He will sometimes graze off of the skeletons of branching lps, but he never nips at the flesh of any of the corals and he even leaves all the mini dusters in the live rock alone. I have never had a lick of problems with him.
