He's being a butt right now and not cooperating with pictures, but for the nub, it looks like in ick spot, but it will get long and thin if he's still for a while and I'm not gawking at him. It is not ick since it is only on his chin and it hasn't spread to anywhere else on him or to Moonshoes.
I'm going to start him on either Jungle or General Cure today since the aquarium salt hasn't been effective for him and the nub hasn't shown any aversion to it. I'm just curious as to what it might be. I'm leaning towards a parasite since it will move in and out of his chin a little bit.
I'll try and get a picture of it, but no guarantees.
