Natural habitat

Cherax snowden is found in tributary creeks to the Oinsok River, recognized for their shallow depths (20-60 cm), moderate flow, and clear water. The substrate typically consists of silt, stones, and larger rocks, with an absence of water plants in most parts.

Where they are found

This species is endemic to Papua New Guinea and is usually found in rivers with a strong current.

Aquarium care

Creating a suitable environment for Cherax boesemani requires a minimum tank size of 80 liters, with appropriate hiding spots using structures like PVC pipes or driftwood. Regular water changes of 15-20% weekly are crucial for maintaining water quality.

Feeding

Cherax snowden requires a varied diet, including commercial pellets, vegetables, and occasional protein sources such as fish or shrimp. Feeding should be done several times a week, ensuring leftovers are removed to prevent water quality deterioration.

Compatibility

This species is best kept alone or in groups of one male to one or two females due to their territorial nature. Housing with slow-moving fish or other crayfish species is discouraged.

Breeding

Breeding in captivity is possible with appropriate water conditions. Females carry eggs under their abdomen and give birth to fully formed juveniles. Careful preparation of the tank environment helps facilitate breeding.
