Fungus on clowntail??

[DanishReefer]

I have this clown who has, what i think, is some kind of fungus on its tail fin. At first i thought it was the other fish nipping on its tail, but it looks too wierd.

Can anyone help me to identify and figure out how to cure my little friend here, thx :)

First picture is from about a month ago, and the video is from today.
