Rhyacichthyidae

The Rhyacichthyidae or loach gobies are a small family of perciform fish in two genera. The three species all inhabit rivers and streams, often with fast flow. R. aspro is widespread in Western Pacific region (China and Japan to New Guinea and the Solomons), but the two remaining species are restricted to New Caledonia and Vanuatu. Little is known about their breeding behavior, but the eggs or larvae float down into the sea where the young grow up, only to later return to the adult river and stream habitat. They are fairly small fish, no more than in standard length.

Protogobius attiti is a species of loach goby which is endemic to nine rivers in South Province, New Caledonia. It occurs in rivers with ultramafic beds. It prefers areas where there is a gravel substrate under overhanging vegetation in slower reaches of fast flowing, clear streams. The rocks and gravel in the areas in which it occurs are usually coated with detritus. When threatened it buries itself in the gravel leaving its eyes, mouth and first dorsal fin above the substrate. Its main prey is small freshwater crustaceans, especially the abundant transparent shrimp which occur in these strea
