Not ID but behavior

What do you think? Is this a mating dance?

The only sharpnose puffer that I know about is the Caribbean Sharpnose C. rostrata (was this photo taken in the Caribbean region). This species lives in harems and the females make algae nests, in which the eggs are laid.

The males regularly visit the females in their harems and display to them. My guess is that this is a social display between the larger male and smaller female to maintain the harem structure.

Thanks for the info Alex. The photo was taken in Bonaire this past February. There appeared to be a whole of fish dancing going on this trip! Many species were interacting. It was great.
