Pond Boss Forums MANAGING AN EXISTING POND Evaluating and adjusting fish populations Pacu

We were at a nice sized pet/pet supply store yesterday and spent some time in the fish section. I was looking at the tropicals and noting the "Max Size" dimensions (5 inch, 6 inch, 10 inch, etc.). Then I got to some Pacu that look like little brothers to the one Rad's friend is holding above and it says "21 inches." That would be quite a fish! No wonder they get turned loose after growing too large for people's aquariums.
