The Warsamson River Crayfish (Cherax Warsamsonicus) emerges as a recent discovery, an exceedingly rare species found solely within the Warsamson River drainage in the western expanse of the Kepala Burung (Vogelkop) peninsula, located in West Papua, Indonesia. Distinguished by its incredibly diverse coloration, this crayfish undoubtedly ranks among the most distinctive-looking crayfish worldwide. Its captivating appearance is matched by its exceptional breeding capabilities within the confines of an aquarium, although the growth rate of its fry is notably sluggish in comparison to the more prevalent US crayfish species popular among aquarium enthusiasts. Notably, numerous instances of successful breeding have been observed within our facility.
Manifesting an actively exploratory behavior, the Warsamson River Crayfish frequently traverses the aquarium floor in pursuit of sustenance. Operating as an omnivorous scavenger, it readily consumes an array of meat-based and plant-based foods. It's important to note that while animal protein can be part of its diet, optimal coloration, health, and breeding potential are often achieved with a predominantly plant-based regimen. Staples such as peas and carrots, both rich in vegetable protein, serve as excellent dietary choices, particularly when provided in frozen form, chopped into smaller portions for juvenile consumption.
Maturing into adulthood ushers in territorial tendencies, potentially resulting in aggressive behavior towards tankmates. To foster a harmonious environment, the provision of ample hiding spots, such as rock formations, driftwood, and PVC pipes, is essential. This becomes even more critical when multiple crayfish coexist. Given its size and waste output, ensuring a minimum 30-gallon, well-filtered aquarium for an individual adult Warsamson River Crayfish is imperative. For groups of comparable size, a larger tank of at least 55 gallons is recommended. While generally hardy, regular water changes are pivotal for maintaining optimal health.
Regarding tankmates, exercise caution. Bottom-dwelling invertebrates and fish should not be housed with larger crayfish, given their opportunistic feeding habits. Conversely, fast-swimming fish occupying mid- and upper-levels can coexist with the Warsamson River Crayfish, provided mindful feeding practices are in place.
In alignment with our commitment to quality, the Warsamson River Crayfish showcases exceptionally high-quality coloration, surpassing alternatives on the market. It's important to note that a temporary shift in color and heightened hiding tendencies post-molting, especially during shipping, are normal occurrences. Within two weeks or less, the vibrant coloration will resurface, indicating a healthy transition.
