(Bleeker, 1855)
Ptereleotris heteroptera is a species of Perciformes in the family Microdesmidae.
These dartfish are reasonably common on lagoon and seaward reefs, where they tend to hang out in small groups over holes under rocks partially buried in sandy areas, diving into the holes at the approach of danger.
Synonyms:
Eleotris heteropterus Bleeker, 1855
Ptereleotris heteropterus (Bleeker, 1855)
Pteroeleotris heteroptera (Bleeker, 1855)
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!
