Common name: Four-eyed butteflyfish

General information

The Foureye Butterflyfish, scientifically known as Chaetodon capistratus, is a distinctive and easily recognizable species in the family Chaetodontidae. This fish is named for the false eye spot near the rear of the dorsal fin, which can confuse predators and give the butterflyfish a better chance to escape. The true eye is camouflaged with a dark stripe that runs across the face.

Foureye Butterflyfish are typically found in pairs or small groups and are known for their peaceful demeanor. They are a popular choice among aquarists due to their striking appearance and interesting behavior.

Care

In the aquarium, Chaetodon capistratus requires a well-established tank with plenty of live rock for grazing and hiding. They can reach up to about 6 inches in length and should be provided with ample space to swim. A varied diet of meaty foods and marine algae is essential for their health, and they may also accept high-quality commercial foods formulated for marine fish.

Reproduction

In the wild, Foureye Butterflyfish form monogamous pairs during the breeding season. They are broadcast spawners, releasing eggs and sperm into the water column where fertilization occurs. Raising the larvae in captivity is challenging and not commonly attempted by hobbyists.

Habitat

Chaetodon capistratus is found in the Western Atlantic, from Massachusetts, USA, to southern Brazil, including the Gulf of Mexico and the Caribbean. They inhabit coral reefs, rocky shores, and seagrass beds, typically at depths ranging from 2 to 20 meters. They prefer areas with abundant coral growth and are often seen near sea fans and brain corals.
