It is a fish of brackish and sea waters which is found in the Indian and western Pacific Oceans.

Nuchequula gerreoides are typically silver with long spines running along their back and stomach.

[3] Nuchequula gerreoides are demersal fish, which means that they normally live close to the floor in seas or lakes.

[1] If the fish are bigger, approximately greater than 7.0 centimeters, their diet would consist of amphipods, polychaetes, and detritus.

The eggs are either released in open water or scattered beneath the surface of the sea floor.
