Lionfish reach sexual maturity in less than a year and grow to over 30 cm in
less than 2 years. That is how they are able to rapidly colonize the entire
Caribbean basin. The 30 year old specimens that have been aged were from public
aquaria. Wild-caught specimens are mostly 3-years old or less.

Atlantic, available here:
