1st off I'm really enjoying the web site. I agree it not smart to put pet fish in the wild.
I read of large snake dieing eating an alligator, scary to think about, either one could ate me. Here in TN we have a problem with a bait fish used for striper fishing, El why I think, being released and it is claimed to be a major eater of native fish eggs. I had some orange carp in one of our farm ponds, I have no ideal where they came from. I haven't caught any for years. not sure if it was the catfish some one put in there of snapping turtles.
