Shrimp

Cherry shrimps are small, ornamental freshwater shrimp. They have been selectively bred
from wild Neocaridina davidi, which are native to the waterways of Taiwan. These adorable shrimps were first introduced into the freshwater aquarium trade in their native Asia, starting in the 1990s. Unlike most crustaceans, cherry shrimp don't have a larval stage; they are direct developers. The young of this species emerge from the eggs as miniature (12mm) versions of the adult.

Crystal red shrimps aren’t quite as hardy as Cherry shrimp, so you may need to be
a little more intentional about cultivating and maintaining ideal water parameters.
If you can provide them with the following parameters, you will see good results.
Temperature: 20 to 25 degrees
Tank size (optimal)
(~40 liters)
pH: 6.0 to 6.8
