Neocaridina davidi is a freshwater shrimp from asian areas which are commonly kept in aquaria. The natural coloration of the shrimp is green-brown. There are a wide range of colors such as red, yellow, orange, green, blue, violet, black, etc., however, the red morph is more frequently sold. The density of coloration on adult shrimp, dependent on breeding, determines their sale price and "quality" (grading).  They prefer clean water, with a pH of 6.5-8, and a temperature of 57–84 °F. They are most comfortable at 72 °F.  N. davidi shrimp are omnivores that may live 1–2 years. These shrimp have previously been classified as Neocaridina heteropoda and Neocaridina denticulata sinensis, however are now known as Neocaridina davidi which is based on the oldest known published description of the species.
