Fish chases reflection.

[Mr.Maska]

I just got a clown tang and he eats fine and looks healthy, but he chases his reflection and nips at the glass. Im wondering if there is a good way to train him out of this by obstructions or letting the algea grow on side glass for a time.
(thats the only place he chases himself).

My pair of Percula have done the same for 7 years; my pair of Melopus have never done this once in 4 years. I guess its very individual thing. Considering what an absolute b..ch my female Melaopus is, you would think that she would be the one chasing her reflection.

my clowns do this as well, and my purple tang too
