Around 340,[2] see text Caridina is a genus of freshwater atyid shrimp.

They are widely found in tropical or subtropical water in Asia, Oceania and Africa.

There is evidence for hybridization between sympatric taxa, requiring care when interpreting molecular phylogenetic analyses that do not use a large number of specimens.

[3] As of March 2022, the Integrated Taxonomic Information System lists the genus Caridina as having 340 species.

[4] These include the following species:[5][6][7][8][9][10] A number of phylogenetic studies have questioned the monophyly of Caridina.
