He looks good after the move, not so much after that. Try and keep the water clean and food pumping, polys grow fins back in no time in my experience. Anyway my money is on a catfish taking that off
It happened over a few days. I noticed it was irritated and then the next evening when I got home, it was just gone. Every other part of him is just fine. No other fins were torn, or even messed with. Here are some more pictures of the carnage. I don’t think it will be growing back.
I’m really not sure it will grow back. There is a decent amount of flesh that was removed at the base of the fin. Still weird that the only the anal fin was touched. Not sure that would attract one of the tankmates to the anal fin.
This is so savage yet so relevant. Poor poly. Never seen anything like this but then again I don't keep catfish with my polys. If he was a male he sure isn't now.......
