The diamond tail flasher wrasse, Paracheilinus attenuatus, is one of the rarest and most highly sought after flasher wrasses. The species was long synonymized with P. mccoskeri but John Randall described and split off the species from specimens collected in the Sychelles. This gorgeous bright-bellied flasher wrasse was recently imported from Kenya where it’s glory was not lost on it’s importers. At least one of these mystery African flasher wrasses has made it’s way to Old Town Aquarium, a hot spot for rare reef fish like the Tigerpyge and more. This extremely rare Paracheilinus attenuatus is on display now, he is eating and displaying and one lucky collector will soon snap up this beauty at a collector’s price as this fish is one of a handful ever imported into the US. Big thanks to Old Town Aquarium for sharing their pictures with us, we hope our chicago-land readers will let us know if they happen to stop by and visit the diamond tail flasher this weekend. Lots more pics after the break.
