The fish Pterois Radiata can be referred with different names like Radiata Lionfish, Radial Firefish, Scorpion Radiata, Tailbar Lionfish, White-lined Lionfish, and Dragonfish. It features red, white and black vertical stripes over the body with large fan structure like pectoral fins and quill-like dorsal fans. It is not reef safe as it is fond of eating invertebretes and small fish. It should be kept with same size or large size fish as small size fish can end up as food.
