What are their natural enemies where they come from?
It’s not quite clear what the natural enemies are of the lionfish in the places where they are indigenous.More than likely there will not be one particular enemy. When a species is native and embedded in the local ecosystem there are usually various checks and balances that regulate its numbers. These checks and balances might range from a particular fungus or bacteria that attacks its eggs, predation of the larvae when they float in the ocean currents, predation on juvenile or small adult specimens, or a parasite that infects adult fish. So even if some of the larger predators in the Caribbean (almost all gone because of overfishing) learn to prey on lionfish, this will likely not be enough to control their numbers. The only thing that is likely to have an impact on lionfish numbers is if we humans become their enemies and start preying on them.
