Curator's Note
Wrasses are known to jump from aquaria. Be sure to have some sort of covering with no large open holes from which your wrasse can escape.
General Description
As a group, the reef-compatable flasher wrasses are a favorite fish for reef aquaria, and the McCoskers’s flasher wrasse (a close relation to the Carpenter's flasher wrasse, Paracheilinus carpenteri) is no exception. Bright coloration, showy finnage and ease of adjusting to captivity are all major plusses for this peaceful, shoaling fish.
Husbandry Concerns
In terms of husbandry, the McCosker's flasher wrasse is similar to most flasher wrasses. It should be kept in an aquarium of at least 30 gallons (larger if you intend to keep a group) with plenty of live rock and a tight fitting lid or eggcrate covering (flasher wrasses are jumpers). Most wrasses appreciate a sandy substrate. If you are going to keep a small group (which is recommended), add the females first; otherwise add them all at the same time. McCosker's flasher wrasses are easily bullied, so be sure to keep them with peaceful tankmates that will not outcompete them for food.
Diet
The McCosker's flasher wrasse should readily accept a captive diet of varied foods including meaty bits of marine flesh such as raw table shrimp, squid, clam, and mussel. We recommend either freezing, briefly steaming or quickly microwaving all raw table marine flesh to minimize the chances of infecting your livestock with parasites.

Supplement raw meaty marine flesh with some type of herbivorous food such as a flake food formulated for herbivores (e.g. Sea Veggies Flakes) or seaweed strips (like Sea Veggies or nori). Nearly all flasher wrasses will readily take commercially prepared pellet foods, frozen foods, and food mixes like Blue Zoo Mix.

Flasher wrasses have a high metabolism and should be fed several small meals a day rather than two large meals. Alternatively use a refugium as part of the system’s filtration. This will provide a constant food supply of small live foods (e.g. copepods).

Mark's Species Tips

Expect male filamented flasher wrasses to display their colors and finnage (“flashing”) to other males and available females. To insure the male does not lose its color, keep one male with two or more females, or keep two males of different species of flasher wrasses in the same sufficiently large aquarium.

To learn more about flasher wrasses, see the article on genus Paracheilinus in the resources section of the Blue Zoo website.

Flasher wrasses are a great substitute for harder to keep anthias.
