Hawaiian Lionfish

The Hawaiian Lionfish is a rare and coveted species endemic to the Hawaiian archipelago, making it one of the most geographically restricted lionfish species in the world. Pterois sphex closely resembles the more common Volitan Lionfish in overall body plan, with fan-like pectoral fins, elongated dorsal spines, and bold banding, but tends to be slightly smaller and displays coloration that leans toward warmer reddish and golden-brown tones. Its relative rarity in the aquarium trade, combined with the allure of its Hawaiian provenance, makes it a prized specimen among serious collectors.

In the wild, the Hawaiian Lionfish inhabits rocky reefs, ledges, and cave overhangs across the Hawaiian island chain, from shallow nearshore waters to depths of around 60 meters. Like other Pterois species, it is a crepuscular and nocturnal ambush predator, spending daylight hours resting in sheltered locations and emerging at dawn and dusk to hunt small fish and crustaceans. Its endemic status means that all specimens in the aquarium trade are collected from Hawaiian waters, which contributes to its higher price point and limited availability.

In aquarium care, the Hawaiian Lionfish is comparable to other medium-sized lionfish species. It requires a minimum tank of 75 gallons with ample rockwork providing caves and overhangs. Like all lionfish, its dorsal, pelvic, and anal fin spines are venomous and demand careful handling during tank maintenance. Once acclimated, this species is a hardy captive that readily accepts frozen meaty foods. Its moderate adult size of around 8 inches makes it more manageable than the larger Volitan Lionfish, while still providing impressive visual impact.
