The Kole Tang is being a prick to the Blue Assessor.
I can't get a pic right now. So I will attach a photo of "one in general". But, WOW are they ever nicer in person than in photos!! I've heard this before, but really photos do no justice, it just GLOWS under the actinics, I didn't expect that!!
I just fed the tank PE Mysis with a drop of fresh squeezed garlic. I blew a bunch at the Jawfish, and he grabbed a few pieces, but spit them out immediately. He is very active though, so I have hope yet. The Kole couldn't care less about him.
