Temminck's Fairy Wrasse (Cirrhilabrus Temminckii)
The Temminck's Fairy Wrasse (Cirrhilabrus temminckii), also known as the Threadfin Wrasse or Peacock Wrasse, is an exquisitely colored marine fish native to the Western Pacific. Males display an olive-green to blue-green body highlighted with vibrant metallic accents and elongated, filamentous pelvic fins used in dramatic courtship displays.
This active, reef-safe carnivore thrives in established aquariums with plenty of swimming room and rockwork hiding spots. A tight-fitting lid is essential to prevent jumping, while a varied diet of meaty frozen foods fed multiple times daily ensures sustained health and coloration.

Materials & care
- Diet: The Temminck's Fairy Wrasse is a dedicated Carnivore (planktivore). In the wild, it forms aggregations to feed on zooplankton in the water column. In the aquarium, it requires multiple feedings per day (2-3 times) to support its high metabolism. Offer a varied diet of high-quality, meaty frozen foods, such as mysis shrimp, brine shrimp, copepods, and fine marine pellets or flake food. Consistent, high-quality nutrition is key to maintaining its brilliant colors.
- Reef Compatibility: It is completely reef safe. This wrasse will not harm corals, soft corals, or most ornamental invertebrates, making it an ideal candidate for any peaceful reef aquarium.
- Temperament: The Temminck's Fairy Wrasse is generally peaceful towards most other community fish. However, it can be aggressive toward other male fairy wrasses, especially those that look similar. It is best kept as a single male with a harem of females, or singly in a peaceful community tank. If housed with other wrasses, it should be one of the last fish introduced to the tank.
- Sleeping Habit: This wrasse sleeps in a mucus cocoon formed within the rockwork or substrate at night and does not require a deep sand bed to burrow into.
Compatibility
Peaceful toward most community fish and safe with corals and ornamental invertebrates. Male fairy wrasses may show aggression toward other males or similar-looking species, so they are best kept singly or with a harem of females.
