Triggerfish

The dorsal fin of the fish is not used for moving. Normally it is hidden. The fish opens the fin for holding in a hole between coral, maybe also for defending itself.

Today only Rinecanthus Picasso , Filefish and Titan triggerfish are here. I have snapped 2-3 triggerfish yet in Red sea. The photos maybe ready soon.
