What kind of catfish is this?

I was just posting in the bullhead thread, and it reminded me I never figured out what this fish is.

Channel Catfish? White Catfish? Something else? I caught it in the middle of a bullhead catching free-for-all, and aside from that day have never caught catfish. What is it, and how big does it get?

Hard to tell from that photo - a channel cat has a forked tail and a white cat a flat tail (as does a flathead - and no, that is not a flat head) I would guess white cat from what I can see

Bullhead would be my best assumption. It is a little hard to tell.. but catfish is what I have the most experience with (being from the south) so that's my guess

Looks like a plain old bullhead (horn pout) to me.
