Ptereleotris monoptera Randall & Hoese, 1985
Lives in reef habitats ranging from shallow coastal slopes to outer reef lagoons and among boulders at the base of slopes. Occurs in pairs, and their burrows may be located in coral rock or sand. They are monogamous and feed on zooplankton. In the wild, they tend to form large, albeit diffuse, colonies.
Ptereleotris monoptera is a light blue to yellowish arrow goby with a deeper shade of blue on the belly, a broad, dark, blotch-like stripe extending from the eye to the chin, and irregular, iridescent blue markings behind the eye.
The species name “monoptera” refers to the unbroken dorsal fin.
This arrow goby is very well suited for a reef tank. It requires good hiding places, as it is very shy at first. Since all arrow gobies are excellent jumpers, the tank should be covered if possible. They live in pairs but also form loose groups in the ocean. They should only be kept with peaceful fish.
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!
