Here's one of several fish that I "caught" today from a private pond (that overflows into a moving creek). Obviously, somebody decided to liberate the occupants of an aquarium - and the "suckers" began to spawn in the wild.
I don't know the name for this fish. But, I think it is a jumbo-version of the aquarium algae-eaters that cling to the glass. The specimens from this pond ranged from 8" to 22".
Obviously, I don't think they represent and exotic predator that would upset a natural food-chain. But, other exotic fish could certainly do so (snakeheads, etc).
The fish's skin was a combination of gator-hide and pliable plastic (each cell was similar to a scale, but connected at all sides - with no overlap). Plus, the skin was full of very sharp bristles that pointed toward the tail. Any attempt to drag a finger along the skin toward the fish's head would result in a shredded finger.
BTW: "Catch" was probably an inappropriate term, since the "bait" was rotenone.
