Ptychognathus insolitus — Boxing Crab

The Boxing Crab is a small freshwater crab notable for its quirky behavior of holding anemones or algae clumps in its claws, mimicking the famous marine boxer crab. Relatively peaceful for a crab, it inhabits shallow streams and can be kept in paludariums or low-water setups. It is an interesting novelty species for nano aquarists.
