Info
Gobiopsis arenaria, a very small, light gray goby with a mottled brown head, a broad saddle over the nape of the neck, three brown saddles along the base of the dorsal fins joined in the middle of the body to form a continuous median stripe, and 5 - 6 narrow brown stripes on the underside, inhabits sand and rubble areas near reefs.
Pelvic fins are fully united, pelvic fins relatively short, caudal fin rounded.
Presence of barbs on the snout, on the tip of the chin and ventrally below the lower jaw give the small goby a rather cute appearance.
Sensory pores are present on the head of the goby.
The scales of the animal are cycloid, the nuchal scales are deeply embedded, and scales are absent on the cheeks and operculum.
The specific name is derived from the Latin "arenarius" (= sandy) and refers to its habitat in sandy pools.
Synonym: Hetereleotris arenarius Snyder, 1908
Jumping guard
A jumping guard prevents (nocturnal) fish from jumping out.
Wrasses, blennies, hawkfishs and gobies jump out of an unprotected tank in fright if their night rest is disturbed, unfortunately these jumpers are found dried up in the morning on carpets, glass edges or later behind the tank.

A small night light also helps, as it provides the fish with a means of orientation in the dark!
