Spot the spotfin

Today's post features the spotfin butterflyfish.  Five butterflyfish species occur on the local reefs.  On a really good dive you can sometimes see 4 species.  Based on my own observations, the spotfin is the third most abundant butterflyfish.  Although I encounter them regularly, and they frequently travel in pairs, they often swim away when approached.  These fish were about 4 inches long, and the photos were taken at depths of 30 to 35 feet.  The spot for which they are named is on the rear end of the dorsal fin.

The usual fleeing posture.

This one swam towards the camera.
