General information

Rainford's Butterflyfish, scientifically known as Chaetodon rainfordi, is a small and colorful species popular among marine aquarists. It is distinguished by its olive to brownish body color with a series of white spots and a distinctive orange patch behind the eyes. This species is relatively small, reaching up to 3 inches in length, making it a suitable choice for smaller reef aquariums.

Care

Rainford's Butterflyfish requires a well-established aquarium with plenty of live rock for grazing and hiding. They are known to be somewhat delicate and can be sensitive to poor water quality, so maintaining pristine conditions is crucial. They primarily feed on algae and small invertebrates, so a varied diet including marine algae, mysis shrimp, and high-quality prepared foods is recommended.

Reproduction

In the wild, Rainford's Butterflyfish are oviparous, with pairs forming during the breeding season. They engage in a courtship dance before releasing eggs and sperm into the water column. In the home aquarium, breeding is rare, but providing a stress-free environment with plenty of hiding spaces can encourage natural behaviors.

Symbiosis

While not known for any specific symbiotic relationships, Rainford's Butterflyfish do play a role in the reef ecosystem by controlling algae growth and helping to maintain coral health.

Habitat

Native to the Western Pacific, Rainford's Butterflyfish are found in coral-rich areas of lagoons and outer reefs. They prefer shallow waters where they can easily access their food sources. Their natural range extends from the Great Barrier Reef to the Solomon Islands and Vanuatu.
