General Description: The Red-Lined Wrasse, also known as the Fiji Christmas Wrasse, is found throughout the Indo-Pacific with exceptional specimens coming from locations such as Fiji. Like all wrasses in the genus Halichoeres, the Red-lined wrasse absolutely requires a moderately-sized to fine sandy substrate in order to be able to bury themselves at night for protection or if felt threatened during daylight. In fact, it is very common for your newly introduced wrasse to immediately bury themselves once released into the aquarium. Red-lined wrasses are one of the most docile of all Halichoeres wrasses. Male Red-lined wrasses have an overall dark green body with many vibrant red stripes in their face in which their common name is derived from. Female or juvenile Red-lined wrasse colors and patterns are more muted; juvenile Red-lined wrasses will also have a pair of ocelli [two black spots that act as “false eyes”] within their dorsal fin in which their species epithet comes from biocellatus – the pair of spots will disappear with maturity. Red-lined wrasses are sought after for not only their active and colorful presence in a reef aquarium, but for their incredible natural ability to control and eliminate nuisance red Planaria flatworms and pyramidellid snails that sometimes hitch hike on corals or live rock. This behavior is exhibited across most Halichoeres wrasses. Red-lined wrasses can reach a size of approximately 4″. Note: Our preferred location to stock Red-lined Wrasse from is Fiji.
Diet Requirements: Red-lined wrasses are carnivores, actively hunting tiny crustaceans (e.g., copepods, featherdusters) throughout the day. A diet consisting of various meaty preparations such as brine shrimp, mysis shrimp, and other mixed frozen foods that contain algae, such as spirulina, will maintain optimal health and coloration. We highly encourage soaking frozen foods in vitamin and fatty acid supplements, as these wrasses have very high metabolisms. Multiple, small feedings per day rather than one large feeding can also help and in turn create more of a natural environment for a Red-lined wrasse as it would feed in the wild. Red-lined wrasses will also accept high quality flake or pellet foods, which is great for nutritional gaps and variety.
Care Requirements: An established, minimum 75 gallon aquarium with a 3″ sandbed at the very least is needed for a Red-lined wrasse. A tight fitting lid is a must because these wrasses are known to jump out of aquariums. Red-lined wrasses enjoy a variety of rock work and crevices to swim through and around while they hunt, but some open swimming space should also be provided for this species. Such live rock arrangements can also help to make it feel secure and encourage more outgoing behavior. Given their peaceful nature, a Red-lined wrasse should not be kept with overly aggressive species, especially those that can outcompete it in food resources. It is best to add a Red-lined wrasse before larger or more active fish in order to allow it to acclimate to the environment. Red-lined wrasses are compatible with other peaceful wrasses, including different species in Halichoeres, though it is best to add them all at once for the best chance at success.
