Pics aren’t really close up enough to tell what’s going on. Based on your description, could be lymphocystis.

Can you get a closer photo? Clowns don't frequently get Lymphocystis and this doesn't look like that to me, but a closer pic might help. A short video can sometimes work as well.

It seems to come an go, some days it’s there and some it’s not. The little guy tends to sleep next to my torch coral with his back fin sometimes rubbing against it, any chance that has to do with it? Or maybe aggression from the older clown?

Besides the wound he’s been swimming around and eating well (feeding rods fish food soaked in Selcon) and doesn’t seem to have any other issues.

Coral burns on clowns are usually brownish colored, but maybe? It still looks too smooth and white to be lymphocystis. It doesn’t look like a bacterial infection. I don’t see anything treatable here. Watch the other clown though, they can be pretty sly in only being aggressive when you aren’t around (grin).
