The princess damselfish (Pomacentrus vaiuli) is a colourful damsel with blue-lined scales, a yellow tint and a dark, blue-ringed eyespot on its dorsal fin. Its colours vary from mostly blue to purple-grey and yellow.

It reaches around 10 cm and lives on reef slopes and outer reefs, usually close to coral and rocks. It feeds on algae and small invertebrates and defends a small territory.

The princess damselfish is found in the western Pacific, including the Philippines, where it is common on coral reefs.
