It's very difficult to sex Lionfish, and breeding in captivity has so far been unsuccessful.

Tank compatibility

Can be kept with other members of the Scorpionfish or Rockfish family. However will attempt to eat any fish smaller than itself.


Difficult to feed. Will need lots of patience to get this fish to take frozen food. Will gladly take live ghost shrimp and will slowly learn to take silversides, krill, squid, cocktail shrimp, scallops or other fresh seafood. These are recommended to be soaked in vitamin supplements before feeding. Do not feed this fish fatty feeder fish such as guppies and goldfish, they can cause liver disease.

Feeding regime

Once or twice day.

Environment specifics

Needs a spacious tank with caves in which to hide.


Not a highly active fish, may slowly swim around the tank, perch on rocks or hide in crevices. Will hide when newly introduced to the tank.


A striking Lionfish which has thick red/brown and white vertical bands on the body and fan-like fins. It has tall quill-like dorsal and pectoral fins.

Species Note

This animal is venomous and can sting you. It's best not to put your hands in the tank with one of these fish unless you are protected. The sting is like a bee sting and is not fatal unless you have an allergic reaction.
