Caridina is a genus of freshwater atyid shrimp. They are widely found in tropical or subtropical water in Asia, Oceania and Africa. They are filter-feeders, collector-gatherers and omnivorous scavengers. They range from 0.9–9.8 mm (C. cantonensis) to 1.2–7.4 mm (C. serrata) in carapace length.
There is evidence for hybridization between sympatric taxa, requiring care when interpreting molecular phylogenetic analyses that do not use a large number of specimens. It includes the following species:
- Caridina ablepsia
