I'm pretty sure you'll have lionfish soon. They've spread all over the Caribbean in the last few years. They are native of the tropical Pacific from Hawaii west to the Indo Pacific and Indian oceans. It's believed they were introduced to the Atlantic through a large aquarium in the Bahamas which kept lionfish but discharged unfiltered water which likely released millions of eggs or larvae over time.
It's believed that there are no natural predators here so many fear they will take over the reefs and deplete many of the natural species here.
Yeah but HOW does such a small fish deplete a large variety of fish population?
