[Reef Puffer]

im just assuming it IS ich... im actually not so sure tho now. in the lfs he looked really good, got him home and in the tank and he looked really bad (covered in white spots, even little sores almost) been what now, a day or two? i dont even see any spots at all now? not sure what it was or is... maybe in my system now? maybe was nothing to begin with? i appreciate the ich info tho if i ever do get an ich outbreak in my tank. this little guy is looking really good. eats all day if he can. at first the kids made me take the baby mollies out so they didnt get eaten. now the kids think its great watching him hunt down the babies and ask me constantly to put them back in... anyways thanx again guys, always the answers i need on canreef!!
