Especially nicely colored female Red Cherry Shrimp with eggs.

 

A group of very nicely colored red cherry shrimp.

 

Male Red Cherry Shrimp.

 

 

 

A young adult female Red Cherry Shrimp that has not fully colored out yet. The same shrimp can be as red as some of the shrimp above in just a few weeks or months.

 

Common Name:

Red Cherry Shrimp

Scientific Name:

Neocaridina denticulata sinensis  "red"

Size:

up to 3 cm

Temperature:

wide range, but best kept at 70F-80F

Water Parameters:

Can live under conditions that are soft and slightly acidic (ph 6.6-7.0) to very hard and alkaline (ph 7.0-8.4 and above). Very adaptable shrimp.

Food:

Biofilm, fish food (flake, pellets etc)

Origin:

Taiwan (this red variety does not occur naturally anywhere, but originally bred in Taiwan. Wild form occurs in Southern China and Taiwan)

Larval Development Type:

Completely Suppressed: Larvae assume a benthic lifestyle after hatching, i.e. they are miniature versions of the adults. There is no planktonic larval stage.

The red cherry shrimp is a red color variation of the dwarf shrimp Neocaridina denticulata sinensis, which hails from southern China, Taiwan and northern Vietnam and which has even been widely introduced into Hawaii.  The red variety of the shrimp was originally bred in Taiwan. The red color variation of N. denticulata sinensis does not occur in the wild.

The red coloration of this shrimp depends on several factors such as mood, water conditions and food.  Hence, when these shrimp first arrive in new aquaria after shipping, they have very little red on their bodies and most animals are extremely pale.  The red coloration returns with time and when the shrimp finally settle in, they maintain their red coloration at all times.  Young animals also need quite some time to become fully colored out.  Females who are carrying eggs are especially deep red, whereas males tend to be much paler than females (see picture of male above). However, females start carrying eggs before they are fully colored up (see picture above).

These animals also display a wide range of temperature tolerance.  My shrimp were kept at temperatures between 50F  and 86F and were eating even at the 50F mark.  Others report that they have kept these shrimp in garden ponds in frost free environments where the Red Cherries were able to withstand temperatures in the 30sF.  Breeding, however, seems to only take place at temperatures of 68F and above.
