Believe it or not, by extra heavy feedings (I'd just read about that elsewhere on this site), raising the temp to 84* and keeping my salinity at 1.019. He mostly beat it himself, being a 6" adult he's pretty hardy, I just helped him along. Even at his worst he ate like a pig. He'd be hanging upside down, begging his tankmates to pick the parasites off of him, it was pathetic. But as soon as I put food in the tank he went nuts. Took about 4 days and he was back to normal, then my cleaner wrasse picked off what was left of the parasites.
