Info
Fusigobius duospilus shows two large black spots on first dorsal fin, anterior spot often vertically elongate at tip of a thin black vertical line extending from base of fin, second spot between fifth and sixth dorsal spines; a faint black spot above anterior margin of pectoral base; caudal peduncle with round to triangular spot; a thin vertical brown bar or oval blotch below eye.
This goby inhabits sandy floors of holes and depressions of clear seaward reefs, the benthicspecies occurs singly or in groups, and is secretive.
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!
