What Thai Micro Crab look like

Limnopilos naninus is a minute hymenosomatid crab with a rounded body and very slender legs. Its translucent tan-gray coloration helps it disappear among moss, roots, and leaf litter.

Behavior & temperament

Thai Micro Crabs are shy, peaceful, and delicate. Keep them in small groups in mature, densely planted or mossy aquaria with shrimp-safe tank mates only. Avoid large fish, aggressive shrimp predators, strong uncovered intakes, and unstable new tanks.

Diet & feeding

Thai Micro Crabs filter-feed and pick at biofilm, microorganisms, powdered foods, crushed shrimp pellets, infusoria, and fine frozen foods. They need mature tanks with constant tiny food particles and should not be starved in sterile setups.

Behind the name

Limnopilos combines Greek roots for lake or marsh and hair; naninus means dwarf.

Plan your tank

Check the numbers before you buy: tank volume, a stocking plan, cycle progress, water changes, and your ongoing care routine.
