Papua Maroon Pulcher Crayfish

The Papua Maroon Pulcher Crayfish is a richly colored freshwater crayfish with maroon, blue, and contrasting pale details that can vary between individuals. Its appearance and deliberate movement make it a rewarding display animal in an aquarium designed around shelter and floor space.

Animal details

• Scientific name: Cherax pulcher
• Size offered: 5–7 cm
• Adult size: Plan for approximately 12–15 cm in body length, excluding the full reach of the claws
• Origin: West Papua, Indonesia
• Water type: Freshwater
• Temperament: Territorial; quiet periods in shelter are normal

Recommended aquarium conditions

• Aquarium: 30 US gallons or larger for one adult
• Temperature: 22–26°C (72–79°F)
• pH: 6.5–7.5
• Water hardness: Maintain adequate minerals and avoid abrupt changes

Create several robust caves with entrances large enough for the animal as it grows. Support rockwork safely, leave areas for walking, and expect some rearrangement of the substrate. Cover every possible escape route, including gaps beside hoses and filter equipment.

Diet and feeding

Provide a varied diet based on sinking crustacean food and plant material. Offer suitable vegetables and leaf material, with occasional small meaty foods. Remove leftovers and ensure food reaches the crayfish rather than relying on whatever remains after fish have eaten.

Compatibility and care

A single-specimen display is the most straightforward approach. Do not assume fish, shrimp, snails, or other crayfish are safe from its claws. Freshly molted animals need privacy and can be injured by otherwise tolerable tankmates. Keep ammonia and nitrite at zero, maintain oxygenation, and carry out regular water changes. Maroon is a trade color description; markings and intensity vary with the individual and its stage of growth.
