McCosker's Flasher Wrasse,
Paracheilinus mccoskeri, is an excellent reef safe wrasse species that will be a hit in most home aquariums. It features a beautiful apple-red body with horizontal blue striping and flaring dorsal and caudal finnage.
McCosker's Wrasse is best kept in a tank with a tightly sealed lid to prevent potential escapes and should be well stocked with live rock and have a sandy substrate. This wrasse will consume a carnivorous diet of fleshy squid, clams, shrimp, and frozen meaty preparations. As it will grow to a maximum of 3 inches, a tank of only 30 gallons is required. It is advised to keep only one McCosker's Flasher Wrasse per tank to curb against territorial aggression.
