A pacu released from a hobbyists tank doesn't make a successful colonization.
You have to a breeding population and I don't see that anywhere for pacu,
even in south Florida. I know this group is opposed to exotic release and
rightfully so but to some extent I think we over state the problem. I have looked for
a long time but I can find no case of an exotic non North American tropical
fish that has established it's self any where but a few small areas that have
warm weather year round. I think that introduced disease is far more dangerous
and should be the major reason given when we try to persuade people not to
release their aquarium fish. Almost everyone knows that tropical fish can't
survive in temperate waters but the diseases they carry sometimes can. I think we
loose some respect for our cause when we try to scare people with the idea of
aquarium fish somehow crowding out our natives. In 99% of the country this just
isn't going to happen and most people know it. Whenever you try to keep
people from doing something by giving out incorrect or exaggerated information you
loose your own credibility and that can keep you from positively influencing
people when it becomes really important that people believe you.
