Pseudocheilinus evanidus, often referred to as the Yellowtail Wrasse, is a striking addition to any marine aquarium. Known for its vibrant colours and active behaviour, this species is a favourite among marine fish enthusiasts.
Temperament and Compatibility: Generally peaceful, Pseudocheilinus evanidus can coexist with a variety of tank mates but may show territorial behaviour towards conspecifics or similar wrasse species. It is best housed singly or in a well-established community with non-aggressive fish.
Diet: This wrasse is carnivorous and thrives on a varied diet including meaty foods such as mysis shrimp, brine shrimp, finely chopped seafood, and specialised marine fish pellets. Feeding multiple times daily in small amounts is recommended to maintain optimal health.
Tank Requirements: A minimum tank size of 75 litres (20 gallons) is advised to provide ample swimming space and hiding spots. The aquarium should be well-decorated with live rock to offer shelter and mimic natural habitat.
Water Parameters and Environment: Maintain stable marine conditions with temperature between 24-27°C, salinity at 1.023-1.025 SG, and pH 8.1-8.4. Moderate water flow and lighting are suitable, replicating reef or rocky coastal environments.
Reef Compatibility: With caution. While generally reef safe, Pseudocheilinus evanidus may prey on small invertebrates such as shrimp or small crabs. Monitor closely if housed in reef tanks.
Overall, Pseudocheilinus evanidus is an excellent choice for hobbyists seeking a colourful, active wrasse that adds interest and movement to a marine aquarium.
