I'm extremely confused. My brother caught what I thought was a blue cat, but someone said it was actually a channel. I've been catching these for ten years, and always thought they were blues. About a week ago I caught what I thought (not sure now) was my first channel cat in the same lake I always fish. It was real green with a bunch of pink in its fins, and the ones I've always thought were blues are real real dark bluish gray. I'll upload some pics, but if these dark ones are channels, why do they look so much different from the green one I caught? Wouldn't they be more alike if they're the same species in the same lake, same spot? P.S. I feel like idiot now, cuz I thougth I knew a lil bit about catfishin, but apparently not. A lil help?
