Cherax pulcher is a species of crayfish from West Papua in Indonesia. It is popular as a freshwater aquarium species across Asia, Europe, and North America.
Males of the species measure 75–98 millimetres (3.0–3.9 in) in length, while females measure 83–90 millimetres (3.3–3.5 in) long. The body is slightly oval in shape. The species has notably large eyes.
The species is brightly colored, with a pink cephalothorax that fades into greenish-grey on the sides. The rostrum is a greenish-blue, and the pleon is dark blue or black, with pinkish-grey or cream coloration on the margins (in some individuals the pleon is greenish-grey with pink speckles). The tail fan is cream-colored or pink around the outside margin. The legs are blue, and the chelae are blue with varying intensities, with cream-colored or white margins.
So far the species has only been found in Hoa Creek near the village of Teminabuan in West Papua, Indonesia. The creek is clear, fast flowing in some places, with a sandy and rocky bottom. source
