I recently got a foxface in my tank and it has started to eat my zoanthids. He voraciously eats anything I put on the veggie clip. When that runs out he goes for the coral, and sometimes before. I have noticed what might be a worm hanging out of him. He doesn't have stringy poop, but I'll occasionally see 1 long string like this. Could worms be increasing his appetite? Any chance that deworming would quell his appetite for corals?
