Overview
What to know before you buy.
A dwarf crayfish that stays under 5 cm and rarely troubles healthy fish, unlike its larger relatives. Provide caves and hiding places, especially around moulting.
Care guide
Keeping Blue Dwarf Mexican Crayfish healthy in a South African setup.
Tank setup
A minimum 30L aquarium suits Blue Dwarf Mexican Crayfish. 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 7–8 and 18–25°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 — sinking foods, vegetable matter. Remove uneaten food within a few hours so it doesn't foul the water.
Behaviour
Peaceful for a crayfish; territorial with own kind. It hides after moulting while the new shell hardens: leave the old shell in the tank, it eats it back for minerals.
Tankmates
Blue Dwarf Mexican Crayfish can catch slow or sleeping fish and will eat smaller invertebrates. Keep it with fast, robust fish.
Breeding
Whether Blue Dwarf Mexican Crayfish breeds at home depends on the species' larval stage; many need brackish or marine conditions to raise young.
