Info
This species owes its name "niger" to the males, which are very extensively covered with melanophores.
The bright yellowish-orange anal fin is particularly striking in the males.
The females can be recognised by an overall lighter appearance 9 basal, dark spots on the anal fin.
Adults inhabit rocky and coral reefs, including tide pools and mud lagoons.
The fertilised eggs are hemispherical and covered with numerous sticky filaments that anchor them in the algae at nesting sites.
The larvae are planktonic and are found mainly in shallow, near-shore waters.
Etymology:
Enneapterygius comes from the Greek, "ennea" stands for the number nine and "pterygion" means small fin, while "niger" comes from Latin and means black.
Also living in the waters around New Caledonia is the blenny Helcogramma novaecaledoniae Fricke, 1994.
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!
