Scientific Name
Hypseleotris kimberleyensis

Common Name
Barnett River gudgeon

Biology
Inhabits clear, rocky pools with moderate flow. Small groups are seen hovering in midwater adjacent to rocky crevices and submerged tree branches (Ref. 5259). Occurs in streams, typically occurring over a mixed substrate of aquatic plants and large sandstone boulders. Solitary in habit, but sometimes forms small groups (Ref. 44894). Sexual dimorphism not as pronounced as in other Hypseleotris species. Caudal fin is truncate in females and rounded in males, males usually darker colored (Ref. 2906, 44894).
