The Imperial Purple Crayfish (Cherax alyciae, formerly known as Cherax peknyi) is a remarkable color variant within the Cherax alyciae species. This unique morph showcases an unprecedented and vibrant purple coloration, making it a truly captivating freshwater crayfish. In addition to its stunning appearance, the Imperial Purple Crayfish is one of the largest crayfish species available.
Breeding the Imperial Purple Crayfish is possible in aquariums, although the fry exhibit slow growth and can display cannibalistic tendencies. Many specimens have successfully reproduced in our facility.
Being an active species, the Imperial Purple Crayfish spends a considerable amount of time exploring the aquarium floor in search of food. It is an omnivorous scavenger, readily consuming both meaty and plant-based foods. While it may occasionally consume ornamental live plants, some aquarists report that Cherax crayfish species, including this one, are less destructive to plants compared to other large crayfish species. As a skilled climber, precautions must be taken to prevent escape from the enclosure.
As the Imperial Purple Crayfish matures, it may develop territorial behavior and exhibit aggression towards other tank inhabitants. To ensure a harmonious environment, providing ample hiding places such as rockwork, driftwood, or PVC pipes is essential, particularly when housing multiple crayfish together. Due to its size and waste production, a well-filtered aquarium with a minimum capacity of 30 gallons is necessary for a single adult. Larger tanks of 55 gallons or more can accommodate multiple adults of similar size. Although reasonably hardy, regular water changes are vital for the optimal health of this species. It is important to note that other bottom-dwelling invertebrates and fish should not be kept with large crayfish. However, mid- and upper-level fast-swimming fish can be compatible, although crayfish are opportunistic feeders and may consume any prey they can catch.
We take pride in the exceptional coloration of our crayfish, including the Imperial Purple Crayfish. The color quality surpasses that of other options available on the market. It is worth mentioning that after molting, which may occur during shipping, the crayfish may temporarily change color and exhibit increased hiding behavior. If your crayfish appears faded in color and you find a molt in the bag or aquarium, there is no cause for concern. This is a normal occurrence, and the bright coloration will typically return within two weeks or less.
