Paracheilinus carpenteri
A small wrasse of outer reef slopes in the western Pacific. Red males with blue lines court females by 'flashing' — darting while spreading their large fins. A reef-safe choice for coral tanks.
Paracheilinus carpenteri, Carpenter's or the redfin flasher wrasse, occurs in the western Pacific from the Philippines north to Taiwan and Iriomote Island and south to northern Bali and Flores, and has recently been recorded from Tonga (FishBase). In the Indian Ocean it is replaced by P. mccoskeri. It reaches 8 cm TL and forms schools over coral or rubble at the base of steep outer reef slopes, pairing during breeding. Males court females by 'flashing' — quick dashes through the water with fins flared and colours intensified — which makes it popular with aquarists. It is named after marine biologist Kent Carpenter, who collected the type specimens. It is regarded as one of the easier wrasses, adapting quickly to a carnivorous diet, and is considered reef-safe as it does not harass invertebrates or nip coral polyps. It is sold in Japanese marine shops and also occurs in the Ryukyu Islands.
