OMG people dismiss Pacu as being bad hunters and are big for nothing. I have about 7 Pacu ranging from 12'' to 24'' and they out compete the oscars, gar, cichla, jaguars cichlids in my pond and all these other fish are adults. These fish will eat anything they get and when they get hungry EVERYTHING IS ON THE MENU. When I throw live food they can follow the live food while its air borne and reach it on time once it hits the water, my pacu have no problem with me either, they are hand tame and while gladly take a shrimp out of my hand, and if keep my hand in there long enough hell they'll go after my hand. What I'm trying to say is they are not the fish that everyone has made them to be, they demand a lot of respect. And I wouldn't expect anything less from a cousin of the Piranha.
