📖 Overview

Found in deep rubble slope areas on reefs, the first specimen collected by the 1997 ‘Twilight Zone’ Expedition (BPBM, John Earle diving with Richard Pyle) at 80 to 90m depth in the famed Blue Holes dive site in Palau. Several individuals have been collected for the aquarium trade from similar depths in Majuro. However, the particularly deep habitat is very poorly sampled and surveyed and that the species may well have a wider range. Another deep-water wrasse, Cirrhilabrus earlei was also discovered on the same dive in Palau as P. zeus, and is also collected for the aquarium trade by the same commercial collectors in Majuro, and these are mainly shipped to Japan .
