Benthic (Ref. 58302). Adults occur from lowland streams and rivers to relatively swift streams at elevations of 1000 m. They often burrow into the substrate with only the eyes showing; feed on filamentous algae, worms, crustaceans, various insects and insects larvae, and suspended food particles; has been long favored as food by the early Hawaiians (Ref. 44091). Larvae develop and metamorphose in the marine zooplankton and as juveniles, about 161 days old, recruit to freshwater streams, where they undergo rapid growth and morphological changes necessary for upstream migration to the adult habitat (Ref. 51037).
成魚在海拔 1000 公尺從低地的溪流與河川出現到相當急流的溪流。 他們時常掘穴進入裡面底部只有眼顯示; 吃絲狀的藻類, 蠕蟲，甲殼動物, 各種不同的昆蟲與昆蟲幼生 , 與浮游的食物粒子; 是長期受到喜愛當作食物藉由早期的夏威夷人.(參考文獻 44091) 仔魚在海洋的浮游動物發育而且變形與稚魚時, 大約 161 天之久 , 淡水溪流的新兵, 在那裡它們歷經對到成魚棲息地的溯溪迴游是必需的迅速的成長與形態學的改變.(參考文獻 51037)
Life cycle and mating behavior

Adults move downstream to their prime breeding just above the estuary; males select crevices and caves formed by rocks on the stream bed where the females will lay their eggs; males guard nests until larvae hatch a day later (Ref. 44091).大洋洲: 馬里亞納群島與夏威夷群島南至萬那度，新加勒多尼亞與斐濟。
