Royal Gramma pestering zoanthids

[jabberwock]

My RG will pretty regularly take a run at both my Zoas and brush up against them in the same spot repeatedly. Not nipping at them, but rubbing them and then those polyps close for a few minutes. I have a Green Star Polyp and a Hollywood stunner that he won't bother. 32 gallon biocube. Water parameters are good. Nitrates and Phosphates are not detectable. I buy Red Sea water from my LFS. Tank is 30 days old. Had the RG for about 2 weeks. Just seems like strange behavior. Other than that he seems fine. I am pretty sure I cannot likely change this behavior, but, any thoughts?

Have you seen it rub on rock other than what the zoas are on . do you notice spots markings on it.

No marks or spots on the fish. It does not rub anywhere else, and in fact, only rubs these two zoas in the same spot on each one.

Same spot again and again.sorry, can't post a video, but I extracted these stills. They are blurry because he is moving fast. I just watched him repeat this 6 times in 90 seconds.

Thanks, it is pretty new. No, the zoas are front and center. I just checked on him. He is curled up under a ledge peacfully. He has a few spots he holes up in.

As you might have guessed, I am now battling ich. Added two little clowns that showed symptoms and died in a week, now the gramma has lots of very small white dots. Quaranteen tank is not feasible at this point. Using ich attack for last three days and have been running running uv sterilizer for five. Things are improving, but I know this won't eradicate it. Just hoping not to lose another fish at this point. The firefish and ywg seem to be doing fine so far. Water change and algae clean up tommorrow...
