Neocaridina davidi (formerly Neocaridina heteropoda) are small freshwater atyid shrimp that are an interesting addition to the aquarium. Providing they are housed with plenty of cover such as plants in order for them to avoid predatory fish, they will thrive in an aquarium. These shrimp are both hardy and useful, as they will eat any left over food and graze on algae.

Avoid any treatments containing copper.
