@KCKWG Agree with Lisa, great that you can keep them at temps below what they supposedly can survive. Little more info on how you do this. Don’t take it personally, but I don’t trust someone’s advice especially on what fish can survive in certain setups that has something to gain that goes against my experiences.
My experience with the high fin banded sharks is that don’t make it over the winter in cold climates, and I am in a much warmer climate than you. On the other side I don’t know if many buyers realize what they look like when they mature and how big they get ( approaching 4’)they go from the cool banded look to a fish that looks like it fell out of an ugly tree and broke every branch on the way down. Personally, I like oddball fish, which is why I tried them in my pond, years back.
