Comments: Have also spawned on glass or rock. Tank was not covered post-metamorphosis. New water used with each spawn. First described by David Starr Jordan in 1904 as Elacatinus oceanops. Bohlke and Robins (1968) divided the genus Gobiosoma into 5 subgenera (Gobiosoma, Austrogobius, Garmannia, Tigrigobius and Elacatinus). G. oceanops is commonly called the “neon goby” and is often confused with G. evelynae (Sharknose goby).

Word origin: Gobiosoma comes from the Latin root gobi, =us meaning a kind of fish and the Greek root =soma meaning a body. The genus oceanops comes from the Greek word ocean, -omeaning the ocean and the Greek root op, =s meaning appearance. Thus Gobiosoma oceanopsis a fish body with the appearance of the ocean (the latter possibly refers to the blue coloration).
