These tiny crabs are fully aquatic, meaning they can always stay immersed in water and can therefore be kept in any aquarium.
Thai Micro Crabs are also known as "false spider crabs," and their scientific name is Limnopilos naiyanetr. 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, making them extremely difficult to find in pet stores or even online. 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.
These crabs resemble spiders in their appearance because of their unusually long legs relative to their bodies. They are usually a silvery color with light brown or beige legs.
NOTE: These crabs are EXTREMELY small (hence the "micro" adjective in their name), so we recommend them for experienced nano-aquarists and shrimp hobbyists ONLY.
Thai Micro Crabs don't grow any larger than 1/2 inch in diameter (including their leg-span), 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.
RECOMMENDED TANK PARAMETERS:
- pH level range: 6.5 - 8.0
Temperature range: 72° - 82° F (22° - 28° C)
- 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, green cabomba, and hairgrass). They tend to make frequent escape attempts, so it is best to keep them in an aquarium with a cover.
