General information

The Mirror Butterflyfish, scientifically known as Chaetodon speculum, is a lesser-known species within the butterflyfish family. It is not commonly found in the aquarium trade, primarily due to its rarity and specific habitat requirements. This species is characterized by its distinctive reflective 'mirror' patch on the sides of its body, which is thought to play a role in communication and species recognition.

Care

Mirror Butterflyfish are best suited for experienced aquarists due to their specialized dietary and environmental needs. They require a mature, well-established reef tank with plenty of live rock for grazing and hiding. Their diet should consist of a variety of foods including marine algae, small crustaceans, and other meaty foods to mimic their natural diet.

Reproduction

Little is known about the reproductive habits of the Mirror Butterflyfish in the wild or in captivity. Like many butterflyfish, they are likely to form monogamous pairs and engage in elaborate courtship displays. Breeding them in captivity is challenging and rarely successful.

Habitat

Mirror Butterflyfish are found in the Indo-Pacific region, typically in clear lagoon and seaward reefs. They prefer areas with abundant coral growth and are often observed in pairs or small groups. Their natural depth range is from shallow waters to depths where light penetration supports coral growth.
