The Pacific Blue Eye has a semi-transparent body that can vary in colour from
pale olive, yellow to bluish. As the common name suggests, the iris of the
Pacific Blue Eye is blue. The
operculum and belly region are silvery. There
is often a series of pearly spots along the side of the body.
The fins of males and females are different shapes. The dorsal, anal and
pelvic fins of males are extended into filaments. The fins can also differ
in colouration, particularly during breeding when the fins of the male can
become brilliantly coloured.
Males grow to 88 mm in length and females grow to 63 mm. They feed on
mosquito larvae and other insects.
The Pacific Blue Eye lives in clear, fast flowing streams and also in
mangrove regions of estuaries.
It is an Australian native species that occurs in coastal streams along the
eastern coast of Australia from northern Queensland to southern New South Wales.
