Compiled by Aquairi from published sources · Published · Updated
Overview
Hoa Creek Crayfish (Cherax holthuisi 'Hoa Creek') is an Australasian freshwater crayfish of the family Parastacidae, listed in the Aquairi knowledge base as an intermediate-level species. West Papuan Cherax with peach-orange body and contrasting red claw tips. Less aggressive than larger Cherax.
Taxonomy
- Family: Parastacidae
- Genus: Cherax
- Scientific name: Cherax holthuisi 'Hoa Creek'
- Common synonyms: Hoa Creek, Holthuisi
Habitat
Cherax is a large Australasian crayfish genus (Parastacidae) with species distributed across Australia, New Guinea and adjacent islands. Many species are aquacultured for food and several brightly coloured forms have entered the ornamental trade since the 2000s. The Aquairi knowledge base records this entry from: West Papua (Indonesia).
Tank requirements
- Minimum tank volume: 80 L (21.1 US gal)
- Adult size: 8-12 cm
- Temperature: 22-28 °C (72-82 °F)
- pH: 7-8.5
- GH: 10-22 °dGH
- KH: 5-14 °dKH
- Lifespan: 3-5 years
Diet
An omnivore. Diet includes plant matter, biofilm, algae, detritus and protein in the form of carrion, small invertebrates or fish remains. In the aquarium a daily portion of sinking pellet, regular blanched vegetables and occasional frozen bloodworm or shrimp meet nutritional needs and reduce intraspecific aggression.
Compatibility
Territorial and semi-aggressive; large adults will harm tank mates and damage plants. A solo, species-only or split-by-divider setup is the only reliable arrangement. Suitable tank mates listed in the Aquairi knowledge base: Solo recommended. Should be kept away from: Fish, Shrimp, Plants.
Breeding
Reproduces in fresh water without a planktonic larval stage. After mating, the female carries the eggs glued to her pleopods for several weeks; hatched juveniles cling to the mother for additional moults before becoming independent. Stable water chemistry and abundant shelter for the brooding female are required. Cherax females typically produce moderate to large broods of comparatively large juveniles, which is one reason for the genus’ aquaculture importance.
Breeding the Hoa Creek Crayfish (Cherax holthuisi)
Overview
Cherax holthuisi is a freshwater crayfish of the family Parastacidae, formally described in 2006 by Lukhaup and Pekny from Aitinjo Lake on the Bird's Head Peninsula in West Papua, Indonesia (western New Guinea). Wild specimens are pink, orange or pale yellow; the 'Hoa Creek' line is one of the peach-orange forms popular in the aquarium hobby. Reported total length is 81-93 mm. The IUCN lists the species as Data Deficient. Like other Cherax, it breeds as a berried female that broods young directly, without a planktonic larval stage.
Sexing
Cherax are sexed by the position of the genital openings: males carry paired papillae at the base of the last pair of walking legs, while females have openings at the base of an earlier pair. Mature males tend to develop larger, heavier claws. Reliable pairing requires examining the underside of an adult animal rather than relying on colour, which varies between individuals.
Conditioning
Stable, well-oxygenated water within the species' tolerated range and a varied omnivorous diet support reproductive condition. As described for the genus, fertilised eggs first develop inside the female's body for roughly four to six weeks before being transferred to the outside of her body, where they rest on the tail.
Breeding Setup
Because adults are territorial, a roomy tank with abundant caves and hides reduces aggression during pairing and protects a moulting or berried female. Cherax mating involves the pair grappling, after which the male deposits sperm; the female then carries the developing eggs on her tail until they hatch.
Berried Female & Young
A berried female holds the eggs, and later the hatched juveniles, attached beneath her abdomen. Development is direct: the young emerge as miniature crayfish rather than free-swimming larvae and remain with the mother for a period before dispersing. Separating the female once juveniles release reduces predation by tank mates.
Common Challenges
Cannibalism of newly released and freshly moulted juveniles is the main obstacle, so plentiful cover and feeding points are important. Adults are not safe with fish, shrimp or plants, so a species-only setup is the practical approach.
