Etymology: Corythoichthys: Greek, korys, korythos = helmet + Greek, ichtys = fish (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; depth range 2 - 30 m (Ref. 30874). Tropical; 35°N - 25°S
Indo-Pacific: Red Sea and East Africa to Tonga, south to northern Australia and New Caledonia.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 16.0 cm TL male/unsexed; (Ref. 30874)
(total): 25-31. Superior trunk and tail ridges discontinuous; lateral trunk ridges straight, ending near anal ring; inferior trunk and tail ridges continuous; body rings 15-17; tail rings 32-39.
Found among corals or sea fans in lagoon and seaward reefs (Ref. 30874). Adults in pairs or small aggregations when in the open or in safe places at night (Ref. 48635). Ovoviviparous (Ref. 205). The male carries the eggs in a brood pouch which is found under the tail (Ref. 205).
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).
