The McCosker's Flasher Wrasse requires a 55 gallon aquarium (or larger) with a tight-fitting lid since it is a jumper. Often found along reef slopes and rubble zones, the McCosker's Flasher Wrasse will often swim near the bottom and tends to form small groups where a male swims back and forth between groups of females. The colors of an adult male intensifies during courtship and he may flare or "flash" his fins to attract females. At this time, we are only able to obtain and offer male McCosker's Flasher Wrasse. We recommend only one male per aquarium display.

The McCosker's Flasher Wrasse diet should include vitamin enriched frozen mysis shrimp, vitamin enriched frozen brine shrimp, and other meaty foods along with a high quality marine flake and marine pellet food.<
