I treated Panda with Maracyn for a week, did a 25% water change. Then, after noticing Panda looking pine-coned, I treated him with Maracyn-two. He no longer looks pine-coned. I noticed mucous like globs floating in the tank and some scales when I changed the water after the Maracyn-two (5 day treatment). The water was really milky and I couldn't see very well when I was siphoning the water out of the tank and next thing I knew, Panda was moving slowly up the vacuum tube. I panicked a little, but reversed the flow in-time to see him slide backward out of the tube. Some flesh is hanging near his right eye, it looks like the bubble around his eye (which I had taken for pop-eye) popped. The water in the tank is still a little milky, but I put a new carbon filter in when I did the water change.
Will watch Panda for a few days to see if he gets better, most likely he will lose what's left of the left side of his caudal fin. Wondcering if they grow back?
