Scientific Name
Kuhlia rupestris

Common Name
Rock flagtail

Biology
Primarily a freshwater inhabitant but may penetrate adjacent marine habitats (Ref. 41640). Adults occur in estuaries and the middle reaches of rivers; usually in relatively fast-flowing, clear streams (Ref. 2847, 79840). Usually in rainforests, as well as in rocky pools below waterfalls (Ref. 44894). Adults are omnivorous, feeding on small fishes, insects, crustaceans and fruits (figs) that drop into the water. Specific breeding habits are unknown, but adults move downstream into estuaries or to the sea to spawn (Ref. 44894). Neither anterolateral groove nor venom gland is present (Ref. 57406). Good food fish (Ref. 5329).
