Pattern and Fins
The body ranges from tan to dark, with pale spots and darker markings along the sides. In adults, the third dorsal spine can extend into a filament. A rounded tail and small spines on the preopercular edge are additional identification features.
Reef Shelter
The range extends from the Red Sea and western Indian Ocean toward Hawaii and other central Pacific islands. Inner reef flats and turbid lagoons provide habitat. Fish retreat into reef holes or burrows, so a rubble patch can hold more cover than it first appears to offer.
Food and Size
Small benthic invertebrates are recorded prey. The species occurs alone or in small groups and spawns on the bottom. Its maximum reference is 6.5 centimeters total length, making a close view of the head and dorsal fin especially useful for identification.
Watch the Dorsal Filament
A long third dorsal spine is a useful adult clue, but younger fish may not show the same extension as mature individuals.
