North as the Carolina's possibly even further North
I was told by someone that there Lionfish in the water off of AC.
They are definitely here, and breeding. I remember reading (I think NY Times) a story about some guy in NY who caught a bunch of baby Lions and was trying to sell them to LFS.
It's a reminder for all of us not to release our pet fish into the ocean. Although legend has it a hurricane in FL released the lionfish - but i'm betting someone let their "pet" go.
