Mayan cichlids and other fish are nuisance species because of people. Displacement of natural native habitats and populations are caused by people introducing non-native species or even species that are native to the country but not that particular locality, driving endemic species to extinction such as the Nile Perch being introduced into Lake Victoria in Africa or the Jaguar cichlid being introduced into native waters in Central America.
Some species down there in FLA have been introduced accidentally through fish hatcheries as well.
So before you go bashing a perfectly innocent fish of doing what it's been programmed to do I suggest you consider your captive fish releasing locals first.

As for the ID mix-up, I would seriously doubt Mr. Bragalots true RT's. The best way to find an actual RT is to arm yourself with the knowledge on how to properly ID one. If they tell you, hey, I finally got some of those RT's in, you look them over and you think not you don't have to take them. Your best bet is to go with someone reputable online though. If you want some that badly it's worth the shipping cost. The second I get some free tankspace I'm filling it with a nice female. I love Uros personally, but I've never had a RT and a female RT's been on my wishlist for a very long time.

The Mayans are too large and agressive for Bluegills and small bass to defend their nests against. The Oscars, Peacocks, Ports and Tilapia do not attack the Bluegill nests. The Mayans also grow too big for the Peacocks to have much of an impact on their populations like they do on the Port Acara. Oddly enough, the much maligned Bowfin has been championed as a native form of control and even eradication of the Mayans but the bass fishing associations are fighting Bowfin stocking because the Bowfins take bass lures.
