Range and Identity
Hypseleotris guentheri is recorded from Indonesia and New Guinea toward island groups including the Carolines, Fiji and Samoa. These named localities establish a regional distribution, not continuous presence on every island. The scientific name helps distinguish it from other fishes called rainbow in common usage.
Habitat and Behavior
Clear flowing streams near the coast provide habitat. Estuarine and mangrove records also occur, including wet-season observations. A coastal stream can contain a salinity gradient, so measured conditions are more useful than assuming that every point in the channel is entirely fresh or fully marine.
Food and Life History
The upper reference is 7.5 centimeters standard length, excluding the tail fin. The available summary does not establish a detailed diet, maximum mass or universal breeding calendar. A life-history pattern from another Hypseleotris is not substituted solely because the fishes share a genus.
Field Note
Include season and salinity when those details are known. They help interpret the connection between a clear coastal stream record and observations nearer an estuary or mangrove.
