I guess it's not impossible but I don't think he is. He eats everything I throw in there. His only bothersome tankmate would be a purple tang that was put in on the same day as him but they have been together for months and nothing new has happened. They get along better now than they ever did. Water quality is good.. mag is a bit low but that shouldn't affect him too much, should it?
