Lionfish are a species of saltwater fish belonging to the scorpionfish family. They are characterized by their bright colorations, long flowing fins and venomous tentacles that form a protective fan around the fish. Lionfishes are regarded as one of the most majestic looking species of fish in the modern aquarium hobby. They are also incredibly hardy and disease resistant, and make great choices for intermediate and experienced aquarists.

Lionfish are a species of saltwater fish belonging to the scorpionfish family.

Lionfishes originate in the tropical reefs of the Indo-Pacific, South Pacific, Red Sea and the Sea of Japan.

Lionfishes are characterized by their warning colorations consisting of red, yellow, white, creamy, brown or black bands.

Saltwater lionfishDespite their ornate appearance, lionfish are actually one of the easier species of saltwater fish to keep in the aquarium. They are very hardy and incredibly disease resistant, and given the right conditions can thrive for many years in captivity. Various lionfish species vary in size from a 2 -18 inches in length, and should be housed in appropriately sized aquariums. Lionfish are a sedentary species and require aquariums with a great deal of rockwork, caves and crevices to hide in. They are also a nocturnal species and will spend most of the daytime hidden in caves or lounging amongst the rock work. Although lionfish aren’t great swimmers, they should also be provided with fairly large open swimming spaces.

Lionfishes are generally a peaceful species of fish. However, they are a predatory species and should not be housed with species of fish that are smaller in size that they are. Several lionfishes can be kept in the same aquarium provided that they have enough space for each fish to establish its own territory.

Care should be taken when handling lionfishes as the sting from their venomous tentacles, while not lethal, can be extremely painful to humans.

Lionfish are carnivores and should be fed on a meaty diet of fish, shrimp, squid and other crustaceans. When first introduced to the aquarium they can be picky eaters and should be enticed with live foods such as fiddler crabs, ghost shrimp and brine shrimp.

Although there are a few reports of lionfish spawning successfully in captivity, there is no information regarding the task of raising the fry to adulthood.
