Caridina multidentata, commonly known as the Amano shrimp, thrives in freshwater habitats. Known for their algae-eating behavior, these transparent shrimp are small, reaching up to 5 cm. They display a unique dotted pattern along their body, contributing to their popularity in aquariums for natural cleaning.

Caridina multidentata, commonly known as the Amano shrimp, is native to freshwater streams and rivers in East Asia. Its geographical distribution includes Japan, Taiwan, and parts of the Korean Peninsula.

This species typically inhabits clean, flowing freshwater environments such as streams and rivers with clear water. The habitat often features a rocky or sandy substrate and is rich in aquatic vegetation. The water temperature generally ranges from 15°C to 28°C (59°F to 82°F), and the pH level is slightly acidic to neutral, around 6.5 to 7.5.

Caridina multidentata plays a crucial role in its ecosystem as a scavenger and algae eater. It helps maintain water quality by consuming biofilm, detritus, and algae, thus contributing to the aquatic food web. The species is well-adapted to areas with moderate water flow, which facilitates its feeding and breeding activities. In its native habitat, it often coexists with other freshwater species such as small fish and invertebrates.
