Included is 5 Thai Micro Crabs (Limnopilos naiyanetr, aka "false spider crabs). These are tiny, fully aquatic crabs that so far have only been found in one specific river in Thailand. They are a very new and rare addition to the aquarium hobby. This is one of the very few types of crab that can live fully immersed in water at all times, so they are able to be kept in any freshwater aquarium. Due to their small size, these crabs pose little or no threat to most fish or other aquarium inhabitants; however, aggressive fish or animals may come after the micro crabs. They tend to do very well in tanks with dwarf shrimp.

Thai Micro Crabs are translucent, which can make them difficult to see. They don't grow any larger than 1/2 inch in diameter, making them great for small tanks and nano tanks. They often act shy when first introduced to a new tank, but eventually will be found clinging to plants and decor and perching atop driftwood. They prefer to have plenty of hiding places, such as caves and plant cover. The way they eat is similar to Singapore Flower Shrimp or Bamboo Shrimp - they filter particles out of the water using tiny hairs on their claws.

- PH level range: 6.5 to 8.0
- Temperature range: 72 to 82 degrees Fahrenheit
- Water type: Soft to hard
- Recommended Aquatic Arts tank mates: Non-aggressive fish (such as Danios or Guppies), dwarf shrimp (such as Red Cherry Shrimp, Blue Velvet Shrimp, Amano Shrimp, etc.). Cichlids, crayfish, and other invertebrates and fish can be aggressive towards these crabs and should not be kept in the same tank.
- Additional notes: Thai Micro Crabs need hiding places such as caves or plant cover (such as java moss, anubias barteri, green cabomba, etc.). They tend to make frequent escape attempts, so it is best to keep them in an aquarium with a cover.


  • These are fully aquatic crabs, meaning they can always stay immersed in water and can therefore be kept in an aquarium!

  • Thai Micro Crabs resemble spiders in appearance because of their unusually long legs. They are usually a silvery color with light brown or beige legs.

  • Thai Micro Crabs are very rare in the aquarium hobby and difficult to find in pet stores or online, so these would make a highly unique addition to any home aquarium!

  • All Aquatic Arts (formerly InvertObsession) brand plants and animals come with a 100% live arrival guarantee, plus free email support directly from the owners!
