Overview
What to know before you buy.
These incredibly small, fully aquatic crabs are peaceful and shy, often resembling tiny spiders. They are filter feeders that sift detritus from the water with their hairy legs and claws. Best kept in a species-only nano tank or with peaceful dwarf shrimp, as they are defenseless against fish.
Key traits
Care guide
Keeping Thai Micro Crab 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 22–28°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
Filter feeder. 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
Thai Micro Crab can catch slow or sleeping fish and will eat smaller invertebrates. Keep it with fast, robust fish.
Breeding
Thai Micro Crab breeds readily in a stable, predator-free tank.
