Russell Lionfish

The Russell Lionfish is a large and impressive member of the Pterois genus, closely resembling the well-known Volitan Lionfish but with subtle distinguishing features that set it apart. Pterois russelli displays the classic lionfish architecture of widely fanned pectoral fins and elongated venomous dorsal spines, with body coloration featuring alternating bands of reddish-brown, tan, and white. One distinguishing characteristic is the relatively shorter pectoral fin rays compared to the Volitan Lionfish, and subtle differences in head and body banding patterns. Growing to approximately 12 inches, it is a substantial fish that commands attention in any large marine setup.

In the wild, the Russell Lionfish ranges across the Western Pacific and Indian Ocean, inhabiting coral reefs, rocky ledges, and coastal structures from shallow waters to moderate depths. It is a crepuscular and nocturnal hunter, spending daylight hours hovering motionlessly under ledges and overhangs before emerging at dusk to pursue small fish and crustaceans. Like other Pterois species, it employs its expansive pectoral fins to corner and trap prey before striking with lightning speed.

In the aquarium, the Russell Lionfish is a hardy and rewarding species that adapts well to captive conditions. A minimum of 125 gallons is recommended to accommodate its adult size. It is safe with corals and will not damage reef structures, but any fish or invertebrate small enough to fit in its mouth is at serious risk. As with all lionfish, the venomous spines pose a genuine hazard during tank maintenance, and aquarists should always exercise caution and keep a first aid plan ready. Once weaned to frozen foods, this species typically thrives for many years in captivity.
