Actinopteri (ray-finned fishes) > Acanthuriformes
(Surgeonfishes) > Chaetodontidae
Etymology: Chaetodon: Greek, chaite = hair + Greek, odous = teeth (Ref. 45335). More on author: Bennett.
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; depth range 1 - 30 m (Ref. ), usually - m (Ref. ). Tropical; 0°C - ; - 30°S
Western Indian Ocean: East Africa (Ref. 33390) to Sri Lanka and the Maldives.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 20.0 cm TL male/unsexed; (Ref. 5372)
Hybrids with C. ephippium known. Usually solitary (Ref. 48636), but may form loose shoals of 5-6 individuals and usually found around isolated coral heads. Territorial and aggressive to other chaetodonts; omnivorous (Ref. 5503). Oviparous (Ref. 205), monogamous (Ref. 52884). Form pairs during breeding (Ref. 205).
Life cycle and mating behavior
Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
Distinct pairing (Ref. 205). Monogamous mating is observed as both obligate and social (Ref. 52884).
