Volitan Lion – Pterois volitans

About this fish

Volitan Lion – Pterois volitans is a saltwater lionfish (commonly sold as “red/common lionfish”) kept for its ambush-style behavior and striking appearance in a properly managed marine aquarium. In practice, it’s a predatory centerpiece fish used in reef or fish-only setups where small tankmates can be safely avoided, and it benefits from stable water quality and secure rockwork to establish a comfortable hunting position. Identification is confirmed to the species level as Pterois volitans on this listing and care guidance.

Features:

• Venomous lionfish spines are primarily for defense, so use caution around the fish during tank maintenance.
• Carnivorous predator: will feed on appropriately sized meaty foods and may eat smaller fish and crustaceans in the aquarium.
• Best kept in a larger, well-established marine aquarium with ample hiding places and open swimming space.
• Works in a reef or fish-only aquarium depending on tankmates; smaller fish are at risk and tankmate selection should be planned carefully.
• Generally considered semi-aggressive and benefits from stable conditions, good filtration, and a secure lid to prevent jumping.
• Recommended husbandry includes routine water testing and water changes, with attention to avoiding ammonia/nitrite issues.
