Cleaner shrimp territorial with coral.?

[GHOSTLY]

So I posted about a stylo frag a while back. Turns out it was being picked on by my cleaner shrimp. After relocating, its gotten healthier and I moved an acro over to it. Ive been feeding him more but now I notice he's picking at the acro in front of the overhang he hangs out at. Is it possible he's territorial with the corals in his area or that maybe he's "cleaning" it

Could be both. Inverts tend to do what they want.

Think it could be picking food instead of flesh
