I've had him for i'd guess around 6 months, he had no issues at all with sps, hammers, torches, but i switched to all lps and he has taken a liking to the acans. doesn't touch any other corals in there, just acans and the scoly, so he will have to go unfortunately. Eats anything you put in the tank, also living with a few other tangs with no issues. Looking to get $80 for him.
