Lance, here is what little I know about doing an ID on a catfish.
White Catfish: slighty forked tail, 22 anal fin rays. Color is not white in this local.
Channel Catfish: 24 to 29 anal fin rays. Young ones have spots on the rear section.
Blue Catfish: 30 to 35 anal fin rays.
Flathead Catfish: mean, ugly and a great fighter. The have a big mouth, are brown, yellow or a mix. You will know one when he bites your bait.
