Bobarb, If you think the Rio Grande Perch looks like a Piranha, wait till you stock the Pacu! Lot of times Pacu are sold as Piranha. When the Pacu comes out of the water they chomp on the hook...kinda like grandpa with a ear of corn! Let us know how your stocking goes, unfortuneately you are starting to get later in the season so growth will be limited. We are all interested to see what happens in the South USA with a full growing season (goes for M/L also). The Pacu can eat about anything so will find a niche all to himself in the states...offhand a guess on my part says one could cross 2+ pounds in 6-7 months.
