While still a rare occurrence, as prey fish populations are declining, some lionfish are turning to cannibalism.  Two recent surveys of stomach contents reported that 4 of 130 lionfish in the Bahamas had consumed other lionfish and in 16 intact lionlish specimen in 157 stomachs in Mexico.  Unfortunately, this probably won't become a natural lionfish population limiting practice.
