would the piranha fish do well there ?

Piranhas are pussycats compared to some of the catfish in the amazon basin. We’re talking real nightmare fish.

"would the piranha fish do well there ?"

Seriously? Well, an individual specimen might actually be able to survive, assuming the water doesn't get to cold. But, I'll bet that the Rio Grande's ecology doesn't lend itself to spawning Piranhas. So, any long-term introduction would be unlikely.

But, it's a good thought.
