Balistes vetula, the queen triggerfish or old wife, is a reef dwelling triggerfish found in the Atlantic Ocean. It is occasionally caught as a gamefish, and sometimes kept in very large marine aquaria.
Etymology[edit]
This fish is called cochino in Cuba,[1] and this is the probable origin of the name Bahía de Cochinos, which is known as the Bay of Pigs in English.
Description[edit]
The queen triggerfish reaches 60 cm (24 in), though most only are about half that length.[2] It is typically blue, purple, turquoise and green with a yellowish throat, and light blue lines on the fins and head.[3] It can change colour somewhat to match its surroundings, or if subjected to stress.[3]
Distribution[edit]
In the western Atlantic, it ranges from Canada to southern Brazil, and in the eastern Atlantic it is found at Ascension, Cape Verde, Azores and south to Angola.[2] It is reasonably common in Florida, the Bahamas and the Caribbean.[3]
Ecology[edit]
The queen triggerfish is typically found at coral and rocky reefs in depths of 3–30 m (9.8–98.4 ft), but it can occur as deep as 275 m (902 ft) and sometimes over areas with sand or seagrass.[2]
It preys on a variety of invertebrates, notably sea urchins.[3]
In the aquarium[edit]
As one of the largest and most aggressive of the triggerfish, this fish is rarely a good choice as a resident in a marine aquarium. It is however a hardy fish for those who can provide it with a proper environment. Because it grows so large and so quickly the minimum aquarium for this fish is a 500-gallon aquarium. Although some sources argue it can be kept in as little a tank as 125 gallons, when it achieves its adult size of two feet it is very unlikely to thrive, and will likely lead to premature death.[citation needed]
Its diet consists of invertebrates. In aquariums shrimp, squid, clams, octopus, scallops, and crab are all good choices of food.
