The fish looks like a tarpon or a huge shad, maybe even a huge golden shiner. But the teeth don't seem to match up with any of those fish so who knows?
At any rate, I only have one of these in my pond.
Once a year, usually around the 4th of July, I strip down, go into the water and go "mano-a-mano" with this fish. I do, however, wear a iron mesh jock strap to prevent potential disaster. It's a big, highly anticipated event and just to keep everyone happy, I usually throw the match, and we have a good laugh over it.
If you notice in FT's first picture, I'm standing just to the left, off frame, nursing my wounds after the melee last year.
