We also have a snakehead issue in south Florida in Dade and Broward county.I completely get where this is coming from as it is somewhat important to keep species from taking over the species of coral that are naturally already there. I guess as time goes on and we learn more about what can be done naturally to replace and or repair these reefs as they disappear decisions can be made and or changed. I am coming at it from the mindset that it is better to have a coral reef of some sorts for creature inhabitation and such than to have a dying one. I grew up in FL so I get the issues you are explaining with lionfish, iguanas, and even the python issue that is now plaguing FL. It is the same issue we are having here in VA/MD with the snakehead fish.
