I have a fridge full of spoonbill that I caught and it has gone sour & spoiled. I have used rotten shad ect for catching catfish, but have never thought about the health effects on the fish eating it.
So do you think feeding a redtail cat rancid fish could be harmfull?
Catfish tend to eat some pretty questionable things in the wild, but I still wouldn't feed anything rancid to one under my care. There are just some fish keeping habits that I can't break. I'm sure what you already fed it won't be a problem though.
Won't. Could pose some health issues. Is your RTC CB or WC?
I would say a WC would be more able to handle it as it is used to scavaging off dead stuff in the wild
