Invasive armored catfish report

Here is what DFW says about Piranhas https://www.wildlife.ca.gov/Conservation/Invasives/Species/Characidae . To be honest, this list makes me sick that people let their damn animals go https://www.wildlife.ca.gov/Conservation/Invasives/Species . 

Does anybody remember the Pacu being caught in the Delta in 2015? http://www.sfgate.com/bayarea/article/Mysterious-piranha-like-fish-caught-in-Delta-6450977.php

Just to get a better idea of how bad it's been and more to the point how bad it will get

Worse case Florida were snakeheads rule
But just to be fair we polluted the west cost with those beautiful
Stripers

They've been catching piranha in Lake of the Ozarks for years. national Geographic even did a study and found they live year round by finding a natural sring feed and going dormant during the winter when the water gets too cold.

A quote from that article:

"A study released by biologists with the University of Florida and North Texas University concluded piranhas could only live in Missouri during the summer months. They would never be able to breed, or over winter here.

In fact there are only three places where piranhas are believed to be able to sustain a population in the U.S. They include the southern portions of Florida, Texas, and California."

All bad,those things are very hardy and omnivorous.they will turn the eco system upside down.ive seen them live in numerous aquariums where everything else died but those things.

You know It is as old as the 

those  pleco are every Hardy fish, I've had many of them in my aquariums almost impossible to kill. even took out some of my ciclids.

Do any "native" species like catfish or even striped bass or other predatory fish go after them?

I used to have a Flowerhorn in my aquarium and he would kill any pleco that in put in the tank.
