McCosker's Flasher Wrasse (Paracheilinus mccoskeri)

The McCosker's Flasher Wrasse is an attractive reef-safe wrasse sure to be the star of your aquarium. This hardy wrasse species adapts well to established home aquariums, making it a beautiful and active addition. The vibrantly colored male McCosker's Flasher Wrasse is predominantly 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 is more subdued. The females also do not feature the large dorsal and anal fins.

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. 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.
