This is my Yellow eye Kole tang that I have purchased to eat the abundant algae growth after my tank was ruined during the power blackout.
This Kole tang is doing a good job and rocks started to have bald patches where the algae have been grazed off.
It seems to be impossible to take a decent picture of the Kole tang as it darts around so quickly. I took the pictures as still shots from videos.
Kole Tang (Ctenochaetus strigosus).
Interestingly my Kole tang seems sometimes to be obsessing about its own reflection in the glass.
