Thai Micro Spider Crab

Thai Micro Crabs are the World's smallest crabs and fully aquatic and the most peaceful aquatic species that can be introduced into the nano tank or small aquarium. In the wilds of Thailand, micro crabs spend most of their time crawling along floating plant roots. The Thai micro crab is also called the micro spider crab. Tiny hairs cover their body and catch floating debris that becomes their food source. These little guys will never hurt anybody and have no defenses and get along fine with rasboras, snails, and shrimp.
