McCosker’s Flasher Wrasse: Dazzling Reef Jewel!

Add a splash of vibrant color and dynamic activity to your marine aquarium with the stunning McCosker’s Flasher Wrasse. Watch males “flash” their brilliant fins in captivating courtship displays.

Overview

The McCosker’s Flasher Wrasse (*Paracheilinus mccoskeri*) is a small, extraordinarily colorful species. Males boast a dazzling reddish-orange body adorned with electric blue horizontal stripes and a bright yellow belly. Their prominent dorsal and anal fins, accented with red and yellow, become even more vivid during their famous “flashing” displays. Females exhibit a more subdued, yet equally charming, coloration. These active wrasses are a joy to observe as they explore your rockwork, seeking small invertebrates.

Care Level

Considered an intermediate-level fish, the McCosker’s Flasher Wrasse is generally peaceful towards most tankmates but males can be assertive with other plankton-eaters or similar wrasses. For optimal display and harmony, keep a single male with multiple females in your healthy aquarium fish community. They adapt well once established, though are sensitive during initial acclimation.

Tank Essentials

A minimum tank size of 200 litres is recommended to provide ample swimming space and accommodate a thriving community. Ensure your aquarium has a secure, tight-fitting lid as these wrasses are known jumpers. Provide plenty of live rock with crevices for hiding, and a sand bed where they can retreat or construct a mucus cocoon for nightly rest.

Diet

As zooplanktivores, McCosker’s Flasher Wrasses thrive on a varied diet. Offer high-quality frozen meaty foods like vitamin-enriched mysis shrimp, brine shrimp, and finely chopped seafood. Supplement with premium marine flakes or pellets. Frequent, small feedings throughout the day are ideal to maintain their health and vibrant coloration.
