Thanks for the Help.
I think it is:
White Fuzzy PatchesFungal infections are usually easy to recognize by their white, cottony appearance. They are commonly secondary infections of open wounds and can be found anywhere on the body of the fish. Eggs may also develop fungal infections. Treat with anti-fungal medication. Preventative medication is often used when eggs are present. Columnaris is a bacterial infection that is usually found on the mouth of the fish, often called cotton mouth. It may respond to antibiotic treatments.
He's pretty beat up and this is the closest thing I've found to what I have:
Fungal Infections
Symptoms: White or cotton-like substance concentrated mainly on scrapes, surface injuries, fins or mouth.
Treatment: Treatment of fungal infections is relatively easy. There are a great many commercially available products for this, including MarOxy by Mardel Laboratories and Super Sulfo and Would Control by Aquatronics.
Information: This is a very common disorder which infects all kinds of tropical fish. It is intensified greatly with fish having damaged fins or cuts and scrapes. It is also much more likely in poor water conditions in which there are unacceptable levels of ammonia or nitrites. Fungal infections are also a sign of bullying by other fish. Fin nippers will damage the fins of other fish making them more susceptible to fungal infections and external bacterial infections such as fin and tail rot.
