Sailfin Tang

[Lfrench]

It looks like something in my tank is taking bites off of his upper fin. Does anyone have any thoughts, is there any way I can prevent it from happening?

Need more information what are all of the tank inhabitants and parameters

Nothing obvious there. Could be the tang or the angel.

Tangs often do end up with random cuts and scrapes that should heal quickly.

Long-term, the blue and sailfin tangs will need a large tank, FYI

Yes I agree it's probably the other tang your tank is too small for this fish
