General info about McCoskers Flasher Wrasse

The McCosker's Flasher Wrasse is a hardy wrasse species that adapts well to established home aquariums. The vibrantly colored male McCosker's Flasher Wrasse is mostly red/orange with blue, horizontal stripes that complement its yellow stomach. The orange dorsal fin is accented with red, yellow, and blue and features a single elongated ray. A gorgeous, red band across the orange anal fin creates an impressive and bold color palette. The female coloration and overall appearance are more subdued. The females also do not feature the large dorsal and anal fins. The McCosker's Flasher Wrasse requires a medium sized or larger aquarium 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 intensify during courtship and he may flare or flash his fins to attract females. We recommend only one male per aquarium display.

Caution with McCoskers Flasher Wrasse

Wrasse are considered jumpers make sure your aquarium has a tight-fitting canopy or screen cover to prevent the Wrasse from jumping out of your aquarium. Wrasse have been known to jump through the smallest of holes in a canopy. 

Wrasses prefer to have a 2" (5cm) sandbed to allow them to burrow into the sand to sleep or when they feel like they are in danger. Some people with bare bottom tanks have also added a Tupperware with a 2" deep sand bed to accommodate the wrasse's needs. 

They are generally peaceful but may display aggression towards members of the same species.
