Radiata Lionfish

Greek Name: (Pterois radiata)



The Radiata Lionfish, also known as the Clearfin Lionfish, or Tailbar Lionfish is characterized by three colors: white, red with black horizontal lines across the body, large pectoral fins shaped like fans, and long dorsal fins that resemble quills.

A 70-gallon or bigger aquarium with a lot of hiding spots is ideal. It will hide as it adjusts to its new home. The top spines are venomous which can trigger reactions similar to bee stings. To soothe itching, wash the region in warm water (100-114o F).

When the fish is first introduced to the aquarium the live saltwater feeder shrimp must be employed to attract the fish to take a bite. Its Radiata Lionfish diet consists of proteins like live shrimp (including ornamental shrimp) as well as live fish and, sometimes crustacean flesh.
