Polyp nipper?

[dunk373]

I have a blue yellow tail damsel. It is picking on my pink stylopora. This is very odd to me why it would do this. Could it be eating the polyp, eating something off of it, bored, or stupid? I have a few fish and they seem to copy eachother. My hippo just eats food I feed untill I got a fox face the fox face picks and now the hippo does too. So could it be possible the damsel is copying the tangs?

I had a yellowtail damsel that pick on mille and pink birdsnest. He was ejected soon after. I like my sps to show polyps, even they are known to be ok with nippers in the tank.

damsels are such a pain they always cause some kind of problem.

Might be something related to the coral rather than the fish. Pic?

heres a pic of the coral the fish will look at the coral swim around a bit and pick one time then swim away do they eat bugs? I dont think there are pests all other acros are doing good and so is this one even though its slow growing
