YourFishStore Lionfish and Scorpions are hand-picked, carefully screened for size and exceptional color, quality, and health by our expert hobbyists.
Lionfish are solitary creatures and quite popular with aquarists. Be careful handling lionfish, since their dorsal spines are venomous and can feel like a strong bee sting. The size of these fish varies, but most members reach an average length of seven inches in captivity. Lions and Scorpions are hardy fish that adapt well to life in captivity. They usually prefer live foods in captivity, but some species convert to frozen foods quickly especially when young. Provide these fishes with ample hiding places and an appropriately sized aquarium for the species.
Lionfish are members of the scorpionfish family (Scorpaenidae) and, in particular, the subfamily Pteroinae. There are 5 genera and approximately 16 individual species in the taxon, with two of these genera and 11 of the species common in the saltwater hobby (Eschmeyer, 1986). The two genera available to hobbyists are Pterois and Dendrochirus; these fish are easily identified by both the adult size of the fish and the shape of their beautiful pectoral fins. In Dendriochirus lionfish, the pectoral rays do not reach the base of the caudal peduncle, and, in general, the fin rays are branched and form a solid fan shape by a connecting membrane that spans each fin ray. Pterois lionfish have elongated fins reaching well past the tail, with many fin rays individually sheathed in a long flowing membrane.
Lionfish are found in the Indo-Pacific (central and western Pacific oceans) and the Red Sea. A few of the lionfish have a wide distribution, such as the Russell's lionfish (Pteriois russelli), which are found on both reef and rocky environments in subtropical and tropical waters, while other lions have extremely limited ranges, such as the Hawaiian lionfish (Pterois sphex), which are found only in waters surrounding the Hawaiian Islands.
Requirements for aquascaping can vary between species; almost all lionfish are dawn/dusk predators and will spend much of their time during the day lounging and hiding. The Antennata and Radiata lions will hide almost exclusively during daylight hours, so caves and covered rockwork are useful, while Volitans lions prefer open waters day and night. Dwarf lions initially will hide during the day; however, once acclimated they will spend much of the day light hours in open view. Juvenile fish of all lionfish species are quite timid and spend daylight hours hiding in the rockwork. The good news is that most lionfish will acclimate to tank life and your individual lighting schedule, so after a few months of hiding and lounging, they will begin to spend much of their time out in the open.
