Etymology: Corythoichthys: Greek, korys, korythos = helmet + Greek, ichtys = fish (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Ecology
Marine; reef-associated; non-migratory (Ref. 52884); depth range 5 - 30 m (Ref. 90102). Tropical; 30°N - 18°S
Indo-Pacific: northern Red Sea and from Ulithi Atoll (Caroline Islands) eastward to the Society Islands south to Indonesia and Papua New Guinea.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 11.0 cm SL male/unsexed; (Ref. 1602)
Adults inhabit lagoon and seaward reefs. Ovoviviparous (Ref. 205). The male carries the eggs in a brood pouch which is found under the tail (Ref. 205). Solitary or paired among corals and algae patches (Ref 90102). Monogamous and always in home-ranging pairs, that is they do not defend an exclusive territory (Ref. 52884).
Life cycle and mating behavior
Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
Monogamous mating is observed as both obligate and genetic (Ref. 52884). Male carries the eggs in a brood pouch (Ref. 205).
