Gobiodon rivulatus (Rüppell 1830)

Characterized by red face with vertical blue lines; uniformly dark brown to light brown or bright green with a longitudinal thin red stripe; red stripe at the base of dorsal fins; absence of scales; complete pelvic fin frenum and basal membrane; depth of body at level of pelvic fins 2.6-3.0 in SL (Ref. 90102).

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).

Amphidromous. Refers to fishes that regularly migrate between freshwater and the sea (in both directions), but not for the purpose of breeding, as in anadromous and catadromous species. Sub-division of diadromous. Migrations should be cyclical and predictable and cover more than 100 km.Characteristic elements in amphidromy are: reproduction in fresh water, passage to sea by newly hatched larvae, a period of feeding and growing at sea usually a few months long, return to fresh water of well-grown juveniles, a further period of feeding and growing in fresh water, followed by reproduction there (Ref. 82692).

Dorsal spines (total): 7; Dorsal soft rays (total): 10 - 11; Analspines: 1; Analsoft rays: 8 - 9

Marine species usually living on coral reefs but also recorded from pools, freshwater streams or lagoon mouths (Ref. 4343). Found on tabletop Acropora corals (Ref. 1602).
