I noticed today that my black sail fin molly has this white-ish stuff on him. It's fluffy, and looks a bit like snot/mucus (for lack of a better description). It looks like a big glob, about the size of the tip of a small finger (maybe smaller) and it's connected to him by a smaller string of it. It looks like it's in front of his fins, on the underside a little to the side. It's hard to tell, but it looks like there may be an injury there. The other fish keep picking at the stuff. Is this fungus? Parasite? Infection from an injury (he's usually picking on the other fish, maybe one of them fought back). How do I treat this?
He's in a 10 gallon tank with three other male mollies. Readings are okay.
Thanks in advance...
