That's a crawdad eatin fish. Beautiful fish. Their mouths get all red like that when they've been chewin on crawdads. Sounds like they've really been keying in on the dads lately. I read in Bassmaster the other day that crawdads come out of hibernation when the water gets around 50 degrees. Makes me wonder if all of a sudden the crawdads are popping out of the mud and it's waking up the big girls a little bit.
