Clownfish sick or fighting?

[Nicksaquatics]

I have 2 clownfish i had for over 1 month and the male has a piece of skin missing. I saw the female picking at him a few times and took pieces of his fins.

Sorry the pictures are not high quality.

I’m just wondering if this is something like Brooklynella or just my female clown picking on the male.

Doesn't look like brook. You could try a freshwater dip and see if it falls off. If it does flukes would be my prime suspect.
