McCosker's Flasher Wrasse

McCosker's Flasher Wrasse is a carnivorous zooplankton feeder that requires high-quality meaty foods multiple times daily. Offer a varied diet of frozen mysis shrimp, frozen copepods, and small frozen foods supplemented with high-quality marine flakes. Feed once daily in small portions to match their natural grazing behavior.

This wrasse is peaceful and active, spending most of its time in the mid-water column darting between rocks and corals. Males are famous for their spectacular spawning displays featuring brilliant red and blue coloration that flashes briefly during courtship rushes. They are generally non-aggressive toward other fish but may be territorial with conspecifics unless the tank is large enough.

Breeding McCosker's Flasher Wrasse in captivity is extremely rare and difficult, as they require very specific environmental triggers and pair bonding conditions rarely replicated in home aquariums. Spawning occurs in the wild during specific seasonal and lunar cycles. Home aquarists should not expect successful breeding without advanced reef-keeping experience and dedicated breeding systems.
