Does my oscar have a fungal infection?

[quasar]

Hey guys so the tip of my oscars tail started out with a little knick and now looks like in the pictures. Is it possible ita fighting with my wolf or banging on rocks, or is it an infection? The wolf hasnt bothered anybody in over a year, partly due to its bad eye sight, but i guess it could happen.


Heres what it looks like now

that tail should be a nice fan, that's missing chunks. wolfie having fun at night, separate and do a large water change and treat the tank with pimafex and medafix to prevent secondary infection. No Oscar should look like that.
