Crystal Red, Red Bee Shrimp
Caridina sp. "bee"

Origin
Crystal Red Shrimp (AKA CRS, Red Bee Shrimp, Scientific name Caridina sp. "bee") is a breed variant of the freshwater Bee shrimp. Normal Bee shrimp can be found in Southern China  or South East Asia. Because the breed form is more intense and vibrant in colour, it has gained popularity in Japan and is now greatly sought after by aquarium hobbyists around the world.

In 1991, Mr. Hisayasu Suzuki of Japan started breeding normal bee shrimps, which are banded with black stripes. He noticed a single red bee shrimp in a batch of about a thousand shrimps and was fascinated by it. This first red bee died but three generations later, he discovered 3 red bee shrimps among the thousands he had bred. After many cycles of selective breeding from redder offspring, he finally arrived at the true red bee. In 1996, he named it "Crystal Red Shrimp" and has been awarded a patent for this recessive red mutation of the normal bee shrimp. Since then Crystal Red Shrimp has been further refined by the founder and other breeders to produce specimens with larger white patches and intensified red.

Characteristic
Crystal Red Shrimp is a fairly small shrimp, growing to about 2.5 cm in adulthood.  However, it is very active but remains quite peaceful towards other tank mates. The average lifespan is about 1.5 to 2 years but the gender is hard to differentiate, especially during juvenile stage. Between the ages of 4.5 and 5 months with a size of at least 2.2 cm, it is ready to reproduce in tank. As Crystal Red Shrimp can crossbreed with normal Bee shrimp and Tiger shrimp which are also of the Caridina species, it is highly recommended not to keep them in the same tank.

In the Aquarium
Crystal Red Shrimp is currently the most favorite freshwater aquarium shrimp. It's unique and distinctive red and white color is unlike any freshwater shrimps. Hobbyist have even refine the species to make it more intense red and white by going through selective breeding. They even grade the shrimps according to the intensity of the white and red patterns on the shell.

Food
Probably due to its size, it is not a particularly great algae consumer; preferring soft mosses and a rich vegetable diet. Some hobbyist even go to the extreme of feeding them with boiled organic spinach. There are a lot of variety of flake/dry food made specially for the Crystal Red Shrimp, but make sure the food does not contain Copper. Copper is a heavy metal and even a small dose is enough to kill any freshwater shrimps!
