One of my Panda Cories got fin rot a couple months ago, which I successfully treated with Melafix in a 5gal QT bucket. However, his right pectoral fin never grew back and eventually all the tissue around it died and he just had the bone sticking out. Pretty weird, I know, but he seemed fine and life was back to "normal".
For about the last week he's been hiding in a very hard to see spot under driftwood in the back. I couldn't even find him all this time until tonight, so I figured he had died for some reason and the shrimps ate him or something.
Anyway, it looks like the fin bone has disintegrated and he's got nothing left there. Except it looks like he may have some sort of fungus (or maybe velvet??) growing from the area. Results: inconclusive - because I can barely see him.
Does anyone have any experience with a situation like this or have any advice?
