Fin Rot?

Is this fin rot? If not, what do you think it is? If it is, what medications do you recommend? If better videos or pictures are needed, ask. I can try my best to get something.

That seems to be Lymphocystis, a common, non-fatal viral disease. Damselfish can be pretty scrappy with one another, and biting is one way this virus gets into a fish. Typically, these white nodules will spread and grow for about 6 to 8 weeks, then go away.

With damsels though - watch for ripped and torn fins, as one will likely try to dominate the others.

I believe it is Lymph, but the fin damage does not look like damage from biting. It is receding, not torn. I will try to get better pictures of the other side where there is actual fin damage.

Tough to see - I looked at the video again. The right pectoral fin is damaged? There is Lymphocystis there as well. There can also be a secondary bacterial component to this....
