The Antennata Lionfish, also known as the Ragged-finned Firefish or Spotfin Lionfish, has red, white, and black vertical stripes along the body; large, fan-like pectoral fins; and tall, quill-like dorsal fins.

A 30 gallon or larger aquarium with numerous hiding places is suitable. It will hide while acclimating to its new environment. The spines on the dorsal, pelvic, and anal fins are venomous, causing reactions similar to a bee sting, only stronger.

The diet consists of meaty foods such as live shrimp (including ornamental shrimp), live fish, and sometimes, crustacean flesh.
