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 and omnivorous scavengers. They range from 0.9–9.8 mm (C. cantonensis) to 1.2–7.4 mm (C. serrata) in carapace length.

Taxonomy and species[edit]

Caridina serratirostris, a widespread freshwater species from the Indo-Pacific region
Caridina dennerli, one of several species restricted to the Indonesian island of Sulawesi
Caridina cantonensis is widely kept in aquariums and several color forms have been achieved through selective breeding

There is evidence for hybridization between sympatric taxa, requiring care when interpreting molecular phylogenetic analyses that do not use a large number of specimens.[2] The genus Caridina includes the following species:[3][4][5]
