Blue Diamond Rili Shrimp (Neocaridina shrimp)

Origins of the Blue Diamond Rili Shrimp

Breeders originally bred Rili shrimp in Taiwan in 2010, and since then they have been universally taken on by aquarium keepers. They are an attractive newer addition to the freshwater Shrimp hobby.

They live in streams and ponds, usually with plenty of plants and often with rocks and wood as a natural substrate.


Rili shrimp are mainly algae and biofilm eaters. They will happily eat any food intended for aquarium use, but some will prefer algae wafers, frozen food and blanched vegetables.

Sexing the Blue Diamond Rili Shrimp

The male is smaller than the female. The male's tail, not being needed to carry eggs, is narrower, and the female is larger and displays a more vibrant colouration.

Breeding the Blue Diamond Rili Shrimp

If there are males and females in your aquarium, Blue Rili Shrimp will most definitely breed and will be able to do so once reached sexual maturity, which is around 4–6 months old.

The female will carry a clutch of yellowish eggs under her tail until they hatch in about 30 days. The newly born Shrimp will look like miniature adult shrimp and will eat the same thing as the adults. If breeding these Shrimp, it is essential to keep them in an aquarium with a sponge filter. This added precaution helps maximise the survival of young Shrimp.
