Cirrhilabrus beauperryi is a compact Western Pacific fairy wrasse recorded from Papua New Guinea and the Solomon Islands, with more recent documentation from Australia's Coral Sea and Great Barrier Reef. Terminal males are largely purple, grading to blue along the lower body and shifting toward greenish or yellow-brown above, with a pale-yellow dorsal fin marked by a broad purple stripe along its base. Males further develop elongated, filamentous pelvic fins, a rounded caudal fin, and a slightly concave profile between the eyes. Initial-phase individuals are a duller purplish red and carry a small dark spot on the upper caudal peduncle, a useful mark for separating this species from the similar Cirrhilabrus punctatus. Adults reach roughly 4 inches.

Adult housing should begin at 40 gallons, though larger volumes are preferable when more than one wrasse is planned, since additional swimming room reduces territorial pressure. Build the aquascape with substantial rockwork that includes caves and crevices for shelter, and leave the water column above the reef structure open for cruising. A mature system with stable parameters and moderate reef flow suits this fish best. Unlike sand-diving wrasses, Beau's Fairy Wrasse retires into rock crevices at night and may produce a mucus cocoon rather than burying itself. A tight-fitting lid is not optional: fairy wrasses are powerful jumpers and are especially prone to leaping when startled or disturbed after dark.
