Description

The minute triplefin is one of the smallest reef fishes of the Indo-West Pacific, ranging from American Samoa to the Ryukyu Islands and Australia. It grows to only about 3 cm and takes its name from the three separate dorsal fins characteristic of the triplefins. The body is greenish-yellow to reddish-yellow with numerous dark spots. It lives on shallow, surge-swept reef edges with brown and coralline algae, to about 5 metres depth, and feeds on small plankton. The hemispherical, adhesive eggs are anchored among algae. The IUCN assesses the species as Least Concern (LC).
