Cleaner Shrimp Effecting Polyp Extension?

[Horace]

I have noticed in the last months that my polyp extension has diminished somewhat on some corals. My water quality seems to be right on and the PE is crazy long at night. I do also have a coral beauty but hes been in there forever, i doubt that he has all the sudden become a major problem. I do see my shrimp constatly swiming over my SPS and his long antenna hit everything as he passes them. What do you guys think?
