Maybe I'm strange (OK, no maybe about it!) but I think my three channel cats are probably my favorite fish and (I've got some gorgeous butterfly koi). I bought three channel cats at the pet store about 3 years ago (probably 3"-4" long) and the guy said they would never make it over winter in a Connecticut pond but I couldn't resist trying anyway. Not only did they make it, they are HUGE now . . . 14" - 16" long each! When we sprung a leak in our pond last winter and had to catch all the fish to overwinter them in a holding tank till we could rebuild the pond I was more worried about the catfish surviving than I was my koi. I just LOVE the catfish with the big wide mouths and the LOOOOONG whiskers. And the fact that they come swimming right up when they see me coming with pellets is great - I love seeing them. If they can catch and eat some of the goldfish babies more power to them - otherwise I would be totally over run with fish. I guess it's a personal preference thing but I just love my huge catfish.
