Overview
What to know before you buy.
The CPO, or Cambarellus patzcuarensis 'Orange', is a small and vibrant dwarf crayfish. Unlike their larger cousins, they are relatively peaceful and can be kept in community tanks with fast-moving fish. Their small size and bright orange color make them a fantastic centerpiece for a nano or small aquarium.
Key traits
Care guide
Keeping Orange Dwarf Crayfish (CPO) healthy in a South African setup.
Tank setup
Add it only to a fully cycled, mature tank: invertebrates tolerate ammonia and nitrite far worse than fish. Use a tight lid and give plenty of caves: crabs and crayfish escape and need a safe spot to moult.
Water parameters
Keep pH 6.5–8 and 18–26°C. Never use copper: most fish medications and some plant fertilisers contain it and it kills invertebrates. Drip-acclimate over at least an hour.
Feeding
Omnivore. Remove uneaten food within a few hours so it doesn't foul the water.
Behaviour
It hides after moulting while the new shell hardens: leave the old shell in the tank, it eats it back for minerals.
Tankmates
Orange Dwarf Crayfish (CPO) can catch slow or sleeping fish and will eat smaller invertebrates. Keep it with fast, robust fish.
Breeding
Orange Dwarf Crayfish (CPO) breeds readily in a stable, predator-free tank.
