Papua Extreme Orange Crayfish

The Papua Extreme Orange Crayfish is offered for its vivid orange appearance and substantial crayfish form. It makes a striking focus for an aquarium built around its needs, with space to explore and secure retreats where it can rest and molt undisturbed.

Animal details

• Scientific name: Cherax sp. sold as Extreme Orange; this trade name does not establish a confirmed species
• Size offered: 5–7 cm
• Adult size: Larger than dwarf crayfish; confirm the current species for a reliable adult-size estimate
• Origin: Papua-region trade stock; precise species and locality are unconfirmed
• Water type: Freshwater
• Temperament: Territorial and opportunistic, particularly around food and shelters

Recommended aquarium conditions

• Aquarium: A spacious species-focused tank; 30 US gallons is a starting point, with final adult housing based on confirmed species
• Temperature: 22–26°C (72–79°F) as a general tropical Cherax target
• pH: 6.5–7.5, with suitable mineral content and stable chemistry

Use smooth caves, sturdy wood, and securely positioned rocks. Leave ample walking space, and expect plants or loose substrate to be moved. Fit a tight lid and close cable and filter gaps; an apparently quiet crayfish can still be a capable climber.

Diet and feeding

Offer sinking crayfish pellets, vegetable-based foods, and appropriate softened vegetables. Small amounts of aquatic protein can add variety, but a constant heavy diet of rich meaty food is unnecessary. Feed near a shelter and remove uneaten pieces.

Compatibility and care

A dedicated setup avoids the risk of caught fish and damaged invertebrates. Other crayfish require much more space and separate retreats, with particular attention during molting. Maintain filtration and regular partial water changes, and avoid copper-based treatments that are unsafe for crustaceans. Color alone cannot distinguish several orange Cherax forms, so ask us about the current identification when adult size or breeding compatibility matters.
