Striped Gudgeon, Gobiomorphus australis (Krefft, 1864)
The Striped Gudgeon is best recognised in the wild by the five to seven dark stripes on the sides of the body, and a dark stripe running posteriorly from the eye.
The Striped Gudgeon has a small mouth that extends posteriorly to a point level with the front margin of the eye. It has two dorsal fins, the soft-rayed second dorsal fin being slightly taller than the spiny dorsal fin.
The background colour of the Striped Gudgeon varies from brown to grey dorsally fading to cream or grey ventrally. It has five to seven dark stripes on the sides of the body, and a dark stripe running posteriorly from the eye.
The pectoral fin base is crossed by a white bar, and the upper pectoral fin base has a dark spot. The two dorsal fins and caudal fin have rows of brown spots.
The species is mostly found in slow-flowing, often muddy water streams.
The Striped Gudgeon is endemic to Australia, occurring in coastal streams of southern Queensland, New South Wales and eastern Victoria.
