Hey experts, are the photos posted by Squeeky actually Bullheads?

I'm trying to learn here, the tail looks forked too much for a Bullhead.

I'm thinking Channel Cat or Blue Cat? In the first photo it appears that the outer margin of anal fin is more rounded like a Channel Cat.

So what type of cat do we have in the photos?
