Damaged/inflamed fin on Leaf Fish

[Corey]

My African Leaf fish, I just noticed today, has a tattered fin on one side. The base of the fin is pink and swollen - it looks like he grew a pink ball joint. It doesn't appear to be bothering him at all.
Anything I should be worried about or should treat?
Thanks.

What are your parameters? I would do a water change if you haven't done one recently. What size tank and what other inhabitants? Anything that might have attacked it or any sharp objects in the tank? I would treat with some melafix to assist in healing. And keep water pristine. Any chance of a picture?
