Dr. John Ernest (Jack) Randall (†), Hawaii
Info
Amblyeleotris downingi Randall, 1994
Found on silty sand-rubble bottom, in association with snapping shrimps Alpheus bellulus and Alpheus ochrostriatus
Sex and mating
There are no known visual differences between the sexes in this genus.
Furthermore, the sex of this species is determined after hatching and cannot be changed (gonochoric). The sex develops during spawning and is determined by the water temperature.
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!
