What is the deal with these snakehead fish in So. Fl? I am not familiar with them. They look mean and nasty. Will they bite or attack you if you are not careful? Are you supposed to kill each one you catch to try to protect the native species? Do they eat or destroy bass populations? Will they move any farther north? Sorry about the many questions, but do not know much about this non native species. I am guessing they were introduced by some one dumping out a home aquarium? Thanks for any info.
