Black Volitan Lionfish (Venomous)The Volitan Lionfish (Pterois volitans) should be housed in a 120+ gallon aquarium (when larger) with plenty of hiding places. While shy at first, they will become comfortable and be very active. The spines on the dorsal, pelvic, and anal fins are venomous and can cause a reaction similar to a very bad bee sting. These spines are used defensively. All Lionfish are safe with corals, but they will eat any fish, and most crustaceans they can fit into
