PSB GO

PSB GO is one kind of hydrosphere microorganisms. It can breathe without consuming oxygen and play an important part in self-purificaiton of water in shrimp tank.

PSB GO is differnet from other PSB products in the market. Aquarium hobbyists can make their own active microorganisms by exposing under sun-ray. It's cost-friendly and health-friendly to your shrimp tank. You can trust what you do by yourself.

Crystal Red Shrimp (also known as CRS in short) is a variety of freshwater crustacean of the genus Caridina. It is exactly the same species as Bee Shrimp; the only difference is in color. Not only has it gained popularity in Japan, it is 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" and has been awarded a patent for this recessive red mutation of the normal bee shrimp. Since then CRS has been further refined by the founder and other breeders to produce specimens with larger white patches and intensified red.

Of the shrimp species, CRS is the most sensitive to fast changes of water parameters due to a smaller gene pool. In fact, the entire world's crystal red shrimps shared common ancestry from the original 3 bee shrimps. Hence, maintaining a proper environmental condition is utmost importance for keeping and breeding – CLEAN (ammonia/nitrite free) water, soft neutral to acidic pH (between 6.2-6.8), and temperatures in the range of 22-28C.

CRS is a fairly small shrimp, growing to about 2.5 cm in adulthood. Probably due to its size, it is not a particularly great algae consumer; preferring soft mosses, flake food and vegetable matter. 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 CRS can crossbreed with normal bee shrimp as well as bumblebee shrimp and tiger shrimp, which are also of the Caridina species, it is highly recommended not to keep them in the same tank.

Discovery

In 1996, Mr. Hisayasu Suzuki of Japan discovered a red form of Caridina sp. among the usual black form offspring. He registered "crystal red shrimp" as a trademark for this autosomal recessive red mutation of the normal bee shrimp. The variety has gained wide popularity since in Japan and worldwide and has been further refined by the founder and other breeders to produce specimens with larger white patches and intensified red. In Japan they are often known as Red Bee Shrimps.

Care

They grow up 2.5 cm in size and live in temperatures up to 27°C (80.6°F), surviving best at 20–25°C (68–77°F) with a pH level of 6.5–7.2. The shrimp are quite sensitive to fast changes of the water parameters, especially when it comes to nitrogenous waste, or nitrite. Soft, slightly acidic water is the ideal breeding environment; breeding in harder alkaline water is not as successful. They reproduce between the ages of 4.5 and 5 months with a size of at least 2.2 cm. The sexes are hard to differentiate, especially on juvenile shrimp.

Crystal red shrimp maybe crossbreed with other bee shrimp as well as bumblebee shrimp and it can cross breed with tiger shrimp, which are also of the Caridina genus.

Grading

Captive-bred Crystal Red shrimps are often graded on a scale of quality denoted as C, B, A, S, SS and SSS, the latter denoting highest quality. The grading of the Crystal Red Shrimp is based on the color and distribution of the markings, and can be very subjective. Some shrimp breeders' websites have charts showing examples of the various grades.
