Something nipping on my torch

[rongy]

Hi reefers, I’ve been out for vacation for 5 days and found out that one of my torch has polyp damage. It seems to me that some fishes were nipping on it. Has anyone experienced this before? How can I find out the culprit? Here’s a list of my fishes:
Blue tang, foxface, green chromis, bangaii cardinal, yellow coris wrasse, clown fish, shrimp/goby pair.

I believe it’s either foxface or the blue tang

From my personal experience I know my foxface nipped my corals which sucks he ate my bubble algae. Now he’s in a fish only system.

Will he “stop” at some point if there are enough food? I suspect that it’s because I didn’t feed enough when I’m on vacation (hard to control with auto-feeder)

Hard to say sometimes when they get the taste they tend to keep going back. I’d say keep him well fed and an eye on him.
