Species

Many, see text

Caridina is a genus of fresh-water atyid shrimps. They are widely found in tropical or subtropical water currents in East Asia. 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.

Use by humans

As food

Caridina species are all edible, and especially C. multidentata is exported.

Three crystal red shrimps feeding on algae

In the aquarium

Due to their algae-eating habits and non-aggressive manner, Caridina are also widely sought after in planted/natural aquariums.

In the aquarium trade, a black-and-white banded variety related to C. cantonensis is called the "diamond shrimp" or "bee shrimp", while a red-and-white banded breed of these shrimps is traded as "crystal red shrimp" or "red bee shrimp".

The wild forms usually have less distinct banding, and are simple traded as "wild bee shrimp" or "orange bee shrimp". Wild Caridina are not usually distinguished to species in the commercial trade, nor are they graded according to the crispness of their pattern.

Selected species

New species are regularly being described. There is evidence for hybridization between sympatric taxa, requiring care when interpreting molecular phylogenetic analyses that do not use a large number of specimens.[1]
