I just acclimated him for about 20min,and tossed it in. I haven't seen him much since then.And not at all yesterday,or today.But I have over 100lbs of good live rock with no compitition for food(copapods) so I figure he's just hiding out and fattening up. I am keeping an eye on the large anemone for any expelled manderine parts.As for ich,I also have a very active cleaner wrasse that keeps the fish clean.He eats everything I throw in the tank(one of those rare ones I guess).
