What the heck is that? It looks like a Cichlid had an affair with a catfish.
Bowfin. Related to gar as I recall.
We have them all over Lake Athens back in the coves. I have paddled right up to them and they seem unfazed. My angler neighbor has caught them, I never have but I suppose I could target them just to say I have. I may have hooked one or two back in the cove I live.
