Crystal Red Shrimp is a color morph of the wild Orange Bee. It was first discovered by Hisayasu Suzuki who soon stabilized and patented the line in Japan in 1996. Selective inbreeding of this species over time has led to the red and white patterns seen today, but has also increased the sensitivity of the shrimp to water parameters.
Crystal Red Shrimp, as well as Crystal Black Shrimp, are graded on the following scale: C, B, A, S, SS, SSS. The “grading” indicates the amount of white to red (or black) ratio on the shrimp, but has no bearing as to quality. Quality of the shrimp is determined by the solidity of the red/black and the white–no visible gaps indicate higher “quality” shrimp.
