A pale blue to light bluish-grey dartgoby, with two curved iridescent blue bands on the gill cover, usually 2-6 filaments trailing from the caudal fin, and a diagonally elongate reddish to violet spot on lower pectoral-fin base.
Thread-tail Dartgobies are very wary, and retreat into crevices and burrows when threatened.
