Summary:
A green coralgoby with five vertical red lines (those on cheek and gill cover do not extend above eye level), no small black spot on the upper rear of the gill cover, and 3-8 series of round or elongate red spots along the side that may join to form stripes. Juveniles have additional vertical blue lines on the body. The species lives amongst the branches of table-like Acropora corals. Coralgobies are capable of changing sex in both directions.

More Info


Distribution

Known in Australia from the northern Great Barrier Reef to One Tree Island, Queensland, and south to the Solitary Islands, New South Wales. Elsewhere the species occurs in the tropical; west Pacific. The species may be more widespread in Australia as it has been misidentified as Gobiodon histrio.
Blue-spotted Coral-gobies mostly shelter among the branches of the table-like coral, Acropora nasuta; also among A. valida, A. millepora (the coarse branched form) and sometimes A. tenuis.

Features

Dorsal fin VI + I,10-11; Anal fin I, 8-10; Pectroal fin 19-21; Caudal fin 6-7 upper or lower unsegmented rays; Vertebrae 26.

Colour

Body yellowish-green to sky-blue, with numerous reddish spots and stripes; 5-6 (usually 5) vertical reddish bars on head and pectoral-fin base, those on cheek and operculum relatively short, usually not or just reaching dorsally beyond dorsal margin of eye; body with 3-8 longitudinal series of rounded or longitudinally elongate scarlet/reddish spots, sometimes joined to form longitudinal stripes; dorsal, anal and caudal fins pale yellow with very narrow black distal margins; no black spot at dorsoposterior corner of operculum.

Remarks

Often confused with Gobiodon histrio.
