Etymology: Gobiodon: Latin, gobius = gudgeon + Greek, odous = teeth (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; depth range 0 - 70 m (Ref. 86942), usually 0 - 2 m (Ref. 89972). Tropical; 38°N - 33°S, 94°E - 165°W
Pacific Ocean: Philippines to the Society Islands, north to southern Japan, south to Australia (including Rowley Shoals, Western Australia) and Tonga.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 4.5 cm SL male/unsexed; (Ref. 48637)
(total): 6 - 7;
soft rays: 8 - 9. Characterized by dark brown body color and lighter brown to reddish head with five vertical blue lines; young fish with additional vertical lines on body; absence of scales; complete pelvic fin frenum and basal membrane; depth of body at level of pelvic fins 2.6-2.9 in SL (Ref. 90102).
Found in groups among branches of Acropora coral (Ref. 9710, 48637); a coral-commensal species (Ref. 72446). Feeds on small invertebrates and zooplanktons (Ref. 89972). Monogamous (Ref. 52884). The male takes care of eggs deposited on a coral branch (Ref. 32163). Has the ability to change sex in both directions to favor reproductive success (Ref. 32163).
Life cycle and mating behavior
Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
The male takes care of eggs deposited on a coral branch (Ref. 32163). Has the ability to change sex in both directions to favor reproductive success (Ref. 32163). Monogamous mating is observed as both obligate and social (Ref. 52884).
