Freshwater shrimp

Applies to most species in this group. Habitat: Streams and ponds. Individual species can differ, so compare with the species numbers above and the linked sources.

Housing & setup

  • Cycled, planted tanks with stable water; moss gives baby shrimp grazing surfaces.

Sources 119354358357373368

Diet

  • Biofilm, algae, blanched vegetables and shrimp pellets.

Sources 119354358357373368

Health watch

  • Avoid copper-based treatments and abrupt temperature, salinity or hardness changes. Maintain stable, species-appropriate mineral content; different freshwater shrimp do not share one water-chemistry recipe.

OverviewCaridina cantonensis, the bee shrimp, is a species of small freshwater shrimp in the family Atyidae. It is native to China, Hong King and possibly Vietnam. These shrimp are scavengers, and eat small pieces of decayed vegetation and algae. Bee shrimp have a life span of about 18 months. — Wikipedia (community-edited)
ReproductionFemale Caridina cantonensis can be distinguished from males by size; the female is larger than the male, and has a deeper abdomen. The female shrimp signal readiness to mate by releasing pheromones into the water which lead the males to the female. During this time swimming activity can be quite vigorous as males search for the females. — Wikipedia (community-edited)
History and namingA phylogenetic analysis conducted by Chen, Chen, and Guo (2020) found Caridina cantonensis to be sister to C. mariae. — Wikipedia (community-edited)

Warm-season highsabout 87°F (up to 88°F in the hottest sampled areas)
Cool-season lowsabout 52°F (down to 51°F in the coldest sampled areas)

Measured at 69 wild occurrence records sampled against WorldClim 2.1 climate data (1970–2000 averages). Air conditions in the range are ecological context, not enclosure settings: microhabitats such as burrows, leaf litter or basking rocks can be cooler, warmer or more humid.
