Cox's gudgeon (Gobiomorphus coxii)

The Cox's gudgeon (Gobiomorphus coxii) is a freshwater fish of the family Eleotridae. Native range: Oceania, restricted to the southeast coast of Australia.

Biology

Populations appear more abundant in southern rivers, in flowing areas, including rapids. Adults are not found in lower reaches but individuals range upstream into areas of altitudes up to 700 m. Rarely found near to the sea. Individuals have been observed climbing dam walls using their pectorals, out of direct water flow. Adults feed on aquatic insects and mosquitofish. Juveniles generally found closer to the sea. During upstream migration these fish are capable of climbing waterfalls and steep dams. The female lays eggs on rocky surfaces and the male guards and fans the nest until hatching several days later.
