XR, there are only two species to my knowledge that can survive outside of extreme south FL, extreme S. Texas, and Hawaii. Those sp are channa argus and channa asiatica (spelling?)
Anyhow just some tid bits of info. To date no channa sp. has had ill effects on the ecosystem they are present in. There are only three places with confirmed breeding populations. One - S. Fl, C. marulius - caught along side natives as well as dozens of other exotics The second is Hawaii - intentionally introduced for food - its an island, they aint going any where, And the third, Potomac River; C. argus. These fish arent spreading either. They are restricted by the falls up stream and by the Atlantic Ocean down stream. There has been no evidence to show any ill effects here either.
There is a fourth possible breeding population in the White River in Arkansas. However this is pretty new and still being researched. I have a really good buddy that is in the middle of the research for the state so I got the inside "scoop" of the net so to speak.
Oh and lets not forget fellas that channa have been imported into the U.S. for well over 50 years. Also not mention the fact that states like Arkansas had farms dedicated to the raising of sp such as C. argus for food!
