Thanks for the replies. I hadn't even thought of the catfish not being
tropical...it was summer time when I collected them and the outside
water temp was within a degree or two of my tropical tanks so I just
put them right in and never gave it a second though. Now that I think
about it though it doesn't make sense to be keeping them in a heated
tank - the heater is coming off tonight.

I think it might better to take the temp down a degree a day?
