Ekologi
marina; sötvatten; brackvatten bentopelagisk; amfidrom (Ref. 59012); djupintervall 0 - 5 m (Ref. 86942). Tropical; 21°C - 28°C (Ref. 12468); 35°N - 6°N
Asia and Oceania: Japan southward to the Philippines, Indonesia, New Guinea and Australia. Reported from Africa: south to Coffee Bay, South Africa (Ref. 2798) and Seychelles (Ref. 4343). Widely distributed over the West tropical Pacific, from Japan to the Philippines, Indonesia, New-Guinea, North of Australia, Vanuatu and New Caledonia (Ref. 87781). The Redigobius genus is actually being revised and especially the bikolanus group that should be splitted into several taxa, leading to a revision of the group distribution also (Ref. 87781).
