I believe he is saying “go away.”
These guys are shy and really don’t like you to come up to see them. Normally they’re sitting right in the coral. And in the picture they look pretty obvious with all those dark red spots. But in the water, they’re actually pretty well camouflaged against the spots of the coral.
If you get too close, the swim away. So, I was happy to get this shot.
