The spectacled triplefin (Ruanoho whero) is a triplefin in the genus Ruanoho. It is commonly found around New Zealand from depths of a few metres to about 30 m, most common in reef areas of broken rock. Its length is between 4 and 8 cm and its head is flattened with large eyes surrounded by a dark band giving rise to its common name. The head and fins have a pattern of fine blue lines. Its large pectoral fins are used as props when resting on the bottom where it spends most of its time.
