The McCosker's Flasher Wrasse is a captivating wrasse species suitable for reef aquariums, and it promises to be the centerpiece of your tank. This resilient species is well-suited to thriving in established home aquariums, bringing both beauty and activity to your underwater world. The male McCosker's Flasher Wrasse boasts vibrant colors, predominantly red or orange, adorned with striking blue horizontal stripes that elegantly contrast its yellow belly. Its dorsal fin is a striking shade of orange, accented by hues of red, yellow, and blue, and features a single elongated ray. An eye-catching red band on the orange anal fin adds to the fish's impressive and bold color palette. In contrast, the females exhibit a more understated coloration and overall appearance, lacking the prominent dorsal and anal fins seen in the males.

For the well-being of the McCosker's Flasher Wrasse, it requires a spacious 55-gallon aquarium, or even larger, equipped with a secure lid to prevent it from leaping out, as this species is known for its jumping behavior. In their natural habitat, these wrasses are often found dwelling along reef slopes and in rubble zones, where they tend to swim near the bottom and form small groups. Among these groups, a male can be observed gracefully moving back and forth to court and attract the females. During this courtship, the male's colors become even more vibrant, and he may engage in fin-flashing to entice the females. It is advisable to keep only one male McCosker's Flasher Wrasse in an aquarium display to avoid territorial conflicts.

To maintain the health of the McCosker's Flasher Wrasse, it's essential to provide a well-rounded diet. This should include vitamin-enriched frozen mysis shrimp, vitamin-enriched frozen brine shrimp, and other meaty foods. Additionally, incorporating high-quality marine flake and marine pellet food into their diet will help ensure their nutritional needs are met.
