Info
Amblygobius bynoensis,
Body pale, with dark stripe edged with pale blue from the snout, through the eye, to just past the pectoral fin, meeting some indistinct barring anteriorly on upper sides. Make burrows under solid objects; hovering close to the substrate. Adults usually in pairs
Sex and mating
There are no known visual differences between the sexes in this genus. However, once a pair has formed, the male is the larger goby.
This goby species is a bidirectional (sex can be changed in both directions) sex changer. The best chance for pairing occurs when the two gobies are already different sizes (at least 1 cm) when purchased.
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!
