I think we are a pretty friendly group here, and there are members who have experience breeding many kinds of catfish. If it can be bred by a hobbyist, one of us has probably done it. We would be happy to give you information if we can.
But it would help if you would tell us about your fish and/or the kind of catfish you are interested in. If you don't know the exact name of the fish, just describe it and we will try to help you find out what it is.
