You got my curiousity up...which is easy to do when it comes to fish and ponds. A little research on Pacu showed they are very temperature intolerant..72 to 83 degrees is their range, according to some net sites. Not a good range for Texas. We go straight from 50 degrees to 90 degrees, it seems. With Tilapia, at least I can get 7 to 9 months of life, Pacu wouldn't last very long here I'm afraid.
