I remember an old fisherman on the beach named Tim told me that they hang a barracuda in a tree or somewhere and if the ants stay away from it the fish is not safe to eat but if the ants go to it then it is safe. Not sure how true it is but there is plenty of other fish to eat there so no need to even take a chance. I do know that in April I will definitely be trying out lion fish for the first time. Heard so many good things about it I just have to find out for myself how good it is. Soon come
