Common name: Black butterflyfish

General information

The Reticulated Butterflyfish, Chaetodon reticulatus, is a striking species known for its intricate reticulated pattern. This fish is a member of the family Chaetodontidae and is appreciated for its beauty and unique markings. It is not as common in the aquarium trade as some other butterflyfish due to its specific dietary requirements.

Care

Chaetodon reticulatus can be a challenging species to keep in home aquariums. They require a varied diet consisting mainly of coral polyps, small invertebrates, and algae. It is essential to provide a well-established tank with plenty of live rock for grazing and hiding. Due to their specialized feeding habits, they are not recommended for beginners.

Reproduction

In the wild, Reticulated Butterflyfish form monogamous pairs during the breeding season. They are pelagic spawners, releasing eggs and sperm into the water column where fertilization occurs. The larvae are planktonic, drifting with the currents until they develop into juveniles. Breeding them in captivity is quite rare and challenging.

Habitat

This species is found in the Indo-Pacific region, from the Red Sea and East Africa to the Hawaiian Islands, and from southern Japan to New Caledonia. They inhabit coral-rich areas of lagoon and seaward reefs, typically at depths of 1 to 30 meters. They are often observed in pairs or small groups, swimming close to the reef structure.
