Saddle-back Butterflyfish (Chaetodon ephippium) Care Guide
Chaetodon ephippium is a large Indo-Pacific butterflyfish with a prominent black dorsal saddle and a trailing dorsal-fin filament in adults.
Overview
Chaetodon ephippium is a marine butterflyfish of the family Chaetodontidae described by Cuvier in 1831. It is a large species reaching about 30 cm, with a yellowish-grey body, a large black spot bordered below by a broad white band on the back, and wavy blue lines on the lower sides. Adults bear a filament extending from the soft part of the dorsal fin.
Taxonomy
- Family: Chaetodontidae
- Genus: Chaetodon
- Scientific name: Chaetodon ephippium Cuvier, 1831
Habitat
The species ranges across the Indo-Pacific from Sri Lanka and the Cocos-Keeling Islands to the Hawaiian, Marquesan and Tuamotu islands, north to southern Japan and south to New South Wales. Adults inhabit clear, coral-rich lagoons and seaward reefs at depths of 0 to 40 m.
Tank requirements
- Minimum tank volume: 500 L
- Temperature: 24-26 °C (75-79 °F)
- pH: 8.1-8.4
- Carbonate hardness: 8-12 °dKH
- Adult size: 20-30 cm (max 30 cm TL)
- Lifespan: 10-15 years
Diet
Chaetodon ephippium is omnivorous, feeding on filamentous algae, small invertebrates, coral polyps and fish eggs. Because it grazes coral polyps it is not considered reef-safe.
Compatibility
The species is peaceful and mid-water swimming, occurring singly, in pairs or in small groups, with juveniles solitary and inshore. Suitable companions include tangs, wrasses and other large peaceful fish; aggressive triggerfish and reef tanks with LPS and soft corals should be avoided.
Breeding
Chaetodon ephippium is oviparous and monogamous with distinct pairing. Captive breeding is not commonly achieved.
Conservation status
IUCN Red List: Least Concern (assessed 2009).
