Well, no change to his eye. My initial observation that the white stuff was gunk was incorrect; it is either his eye or part of his eye now, as it does indeed NOT move. I have ordered a different eye antibiotic but am not expecting any change and will give up on the eye if that doesn't work.

On the plus side, he has gained a lot of weight and is now in decent body condition thanks to panacur and good old fashioned nummers. He prefers to be fed and watered by hand even though he really doesn't like me very much.

Some of his vent crusties have fallen off which is a relief - hopefully nothing nasty is brewing under there. I am continuing with polysporin application until it looks to be thoroughly healed.

All in all, I'm happy with his progress. He'll always be special needs, though, and I have no idea what I'll do with him when he's ready to move on as I really haven't got room for a tank that is big enough. We'll see.
