Jsand13 --
That is one delicious looking catfish, although I'm glad to hear you threw him back to get even bigger.
I don't have any that big, but I noticed last night some extreme color mottling on one of the 25-30 inchers that was coming up for food. A large part of it's top, from its head to halfway between the top fin and tail fin, were pinkish-white (kind of hard to really tell in green tinted water). I've seen this before. By summer, they are back to normal colors.
If you just have the one, probably no problem. Every few years I'm plagued by several large ones that become menaces. I put CC in every few years, and there are always a few that become real hook smart/shy. This year I put 50 CC into a cage so that we can have neighborhood catfish dinners, but the CC won't be eating everything in sight and digging holes in the side of my pond.
