fish fight!

I just added royal gramma to my 29 gal tank. I already had yellow tail damsel in there and he is being super aggressive toward the new guy. its been 2 days and nothing has changed, the royal gramma is about 2/3 of the damsels size. Is there anything I can do make them at peace? I moved the rocks around cause I heard that has worked for some ppl but so far there has been no change. there is also a lawnmower blenny and an ocellaris clownfish in the tank that the damsel is fine with, not sure why he doesnt like this guy.

Your damsel is being a damsel. Damsels (including clownfish, which are damsels) are some of the most belligerent fish one can keep. Your other fish are established, so the damsel picks on anything new, and will likely continue to do so.
Your best bet is to lose the damsel and hope the clown minds its manners.
