General Description: The Yellowfin Flasher Wrasse is native to the Indo-Pacific, Indian Ocean and Australia. Like all flasher wrasses in the genus Paracheilinus, the Yellowfin flasher wrasse is an attractive, relatively hardy, active and peaceful fish suited for reef aquaria. Male Yellowfin flasher wrasses are brightly colored, having an overall red to orange body with faint-colored horizontal stripes that run the length of it. The orange dorsal fin has two elongated red rays, and the anal fin is bright yellow in which this species gets its name. Female or immature male Yellowfin flasher wrasses have more muted colors and no elaborate dorsal fins. Yellowfin flasher wrasses do best when kept in groups because they are a natural shoaling fish, and this also encourages the male Yellowfin flasher wrasse to showcase their best coloration. Keep one male per aquarium with two or more females. The male Yellowfin flasher wrasse closely resembles both male McCosker’s Flasher Wrasse (Paracheilinus mccoskeri) and male Carpenter’s Flasher Wrasse (Paracheilinus carpenteri), however there are differences in ray number among all three species (McCosker’s = 1; Carpenter’s = 3 or 4) and both latter species do not have the yellow anal fin. Yellowfin flasher wrasses can reach a size of approximately 3″. Note: This species is infrequently available compared to other similar Paracheilinus sp.
Diet Requirements: Yellowfin flasher wrasses are carnivores, actively hunting tiny crustaceans (e.g., copepods) 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 flasher 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 Yellowfin flasher wrasse as it would feed in the wild. Yellowfin flasher wrasses may also accept high quality flake or pellet foods, which is great for nutritional gaps and variety.
Care Requirements: An established, minimum 30 gallon aquarium is required for a single Yellowfin flasher wrasse. However, a 55 gallon aquarium is preferred and an even larger tank is recommended for a group. A tight fitting lid is a must because these wrasses are known to jump out of aquariums. Yellowfin flasher wrasses enjoy a variety of rock work and crevices to swim through and around while they hunt. Such live rock arrangements can also help to make it feel secure and encourage more outgoing behavior. The Yellowfin flasher wrasse is not tolerable of nitrite or ammonia spikes, and an established tank also offers microinvertebrates and crustaceans that naturally accumulate over time as the aquarium ages for it to prey on. Given their peaceful and timid nature, a Yellowfin flasher wrasse can be easily bullied and therefore should not be kept with overly aggressive species, especially those that can outcompete it in food resources. It is best to add a single, or group, of Yellowfin flasher wrasses before larger or more active fish in order to allow them to acclimate to the environment and begin feeding. If you’re interested in a group, add all individuals simultaneously for the best success, or females altogether first before adding a male. Recommended water conditions, 72-78° F, KH 8-12, pH 8.1-8.4, salinity 1.020-1.025.
