Thanks. I am getting a 3.5" GF. I don't have any xenias, but do have a mix of pollyps, shrooms, leather corals, montis, acros, porites, 2 small clams (which are probably goners), torches, and candy corals.
Large Angel - thanks for referring rarefish.com. From what they tell me they actually do treat the GF's for all types of parites, including flukes. The one I am getting they have had for some time and has been treated with copper and fromaldihyde.
