Great color on that fish! Actually that's a black bullhead with bright yellow coloring. This is just speculation, but I think at spring spawning time their color intensifies, and they develop bright yellow coloring.
You can always tell the black bullhead apart from the other types of bullheads by the bar at the base of the tail.The bar at the base of the tail is absent on the yellow and brown bullhead. Black cats also have grey to black chin whiskers and a very short anal fin.Your fish displays all those characteristics. It's definitely a black bullhead.Yellow bullheads have a much longer anal fin and white chin whiskers.
In Texas the black bull is by far the most common bullhead followed by the yellow bull. I don't think Texas has brown bullheads? If it does, they're very few. Browns are mainly found in the northern and southeastern states.
