Redigobius

Redigobius is a genus of fish in the goby family, Oxudercidae, known commonly as dualspot gobies.

[1] They are native to the western Indo-Pacific region, where they occur in estuaries and freshwater habitats just above the tidal influence.

[2] Some of these gobies are abundant fish species.

The most widespread is the speckled goby (R. bikolanus),[2] which occurs throughout the western Pacific Ocean and from Australia to Africa.

[2] The Fijian endemic Lever's goby (R. leveri) is featured on the ten-dollar bill in the 2013 series of Fijian currency.
