Neon has... something.
He's a tail biter, every few days to a week he'll "trim" his tail. Well, for over a week now, the top half of his tail has been short! Usually he lets it heal to a certain point and then starts biting it. Also, his anal fin has a few tears...

I can't take a picture because one of the batteries in my camera is gone and I can't find any more. I'm not sure if he's tearing fins on driftwood or chewing them up or what, it just looks so much more ragged than before. But... there is no blackened edges...
EDIT: Oh, also, I realize that if it IS fin rot to QT him with 1 tsp AQ salt/gallon with daily 100% water changes. Just throwing that out so people don't have to take time out of their day reciting this (=
