Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; depth range 10 - 36 m (Ref. 1602). Tropical; 30°N - 24°S
Central Pacific, including Hawaiian Islands. Indian Ocean species were re-identified as Canthigaster petersii (Ref. 123151).
Population from the Philippines, Indonesia, New Guinea, Queensland, and Belau differs in coloration (formerly Canthigaster papua);
Replaced by Canthigaster margaritata in the Red Sea.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 12.1 cm TL male/unsexed; (Ref. 126022); max. published weight: 32.16 g (Ref. 126022)
Inhabit sheltered rocky reefs (Ref. 48637). Also live in intertidal reef flats, lagoon and seaward reefs. Occur over open barren areas, also among corals and under ledges (Ref. 9710). Benthopelagic (Ref. 58302). Often found in pairs, sometimes in small groups. Feed mainly on filamentous red and green algae and coralline red algae but also on corals, tunicates, mollusks, echinoderms, polychaetes, crustaceans and bryozoans. Common (Ref. 9710). Monogamous (Ref. 52884).
Life cycle and mating behavior
Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
Oviparous (Ref. 205). Displays facultative monogamy where males are constrained to mate with a single female due to resource limitation (Ref. 52884).
