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 to 9.8 mm (C. cantonensis) to 1.2–7.4 mm (C. serrata) in carapace length.

Taxonomy and species

File:Caridina-dennerli.jpg, one of several species restricted to the Indonesian island of Sulawesi]]

File:Caridina-cf-cantonensis-red-bee.jpg 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.{{cite journal |author=Kristina von Rintelen, Thomas von Rintelen & Matthias Glaubrecht |year=2007 |title=Molecular phylogeny and diversification of freshwater shrimps (Decapoda, Atyidae, Caridina) from ancient Lake Poso (Sulawesi, Indonesia) – the importance of being colourful |journal=Molecular Phylogenetics and Evolution |volume=45 |issue=3 |pages=1033–1041 |doi=10.1016/j.ympev.2007.07.002 |pmid=17702608 |url=http://download.naturkundemuseum-berlin.de/thomas.rintelen/Rintelen%20et%20al%202007%203.pdf }}

Threats and Conservation

As of March 2023, the IUCN Red List lists 56 Caridina species as threatened, with 18 listed as critically endangered, 5 listed as endangered, and 33 listed as vulnerable.{{cite web
