This species occupies a very specific microhabitat and depth range, observed and collected exclusively from a very sheltered and coral-rich lagoon (Kwatisore South Bay) with limited water flow and water temperatures that are commonly elevated above that of the surrounding reef areas (usually 30-31° C). Depth range of occurrence is rather narrow (25-30 m depth) and it was not found either deeper or shallower than this, despite extensive searching. It was found resting and moving about on the surfaces of the extensive foliose and plating coral colonies (mostly Pachyseris and Turbinaria spp. colonies) in the lagoon. Found in association with other coral goby species, including E. atriventris, E. fallax, E. lachdeberei, and Trimma emeryi
