Blue-banded Stiphodon Goby

Stiphodon atropurpureus is among the most sought-after nano gobies in the specialist freshwater hobby. Mature males are breathtaking: a warm amber-orange base is overlaid with two to three electric-blue lateral stripes that flash under bright lighting. Females are drab brown by comparison but share the same compact, dorsoventrally flattened body ideal for clinging to current-swept rock faces. Found in clear, fast-flowing lowland to upland streams of Papua New Guinea and eastern Indonesia, this amphidromous species requires marine larval development, making captive breeding impractical. In the aquarium the focus should be on replicating its natural habitat: strong flow, smooth stones rich in periphyton, and pristine water quality. Males defend territories but rarely harm each other or other species.
