Yes, people have realeased this fish in the back into the wild, for years more years than most of us have been alive. However the atlantic ocean would get to cold for these fish to really survive and thrive, but in recent years the atlantic has been heating up for longer period of time and higher heat. This generally accounts for many more intence hurricanes in the altantic, I know this because I live in S. Florida and have spent much more time in recent year watching the weather. There has been research and even a paper writen not on a migration but and exspansion on suitable enviroment for this fish and many others that are not dangerous to the atlantic because of the warming of the atlantic ocean. The release of any aqurium fish back into any eco system is a bad thing and does occur, but you can not put the blame fully on the shoulder of the hobbiest. If the enviroment the fish is release into can not substain that year round, most fish die off. Lets look at S. Florida in our canals and lakes. You can find all most any tropical fish you could want buy, are they there because of hobbiest yes, but a lot more fish are released by fish farms just in the day of bussiness. Now factor in a simple slow moving tropical storm not even a hurricane, that causes heavey rains. There hold pen will over flow releasing hundreds od fish into the eco system. As a hobbiest I must except part of the blame even though I never released a fish back into the wild, but because it our responciblity to inform other the reasons why not to do this. I am not willing to take all the blame when I know the carelessness of bussiness world.
