Add to cart Crystal Black Shrimp (Caridina cf. cantonensis) $9.99 Crystal Black Shrimp are a selectively bred form of Caridina which have been developed from wild specimens showing subtle black and white coloration. They are enormously popular due to their striking, high contrast coloration and can be a bit more delicate than some of the more common Neocaridina species, so are best kept by hobbyists with some experience keeping shrimp already. Crystal Black Shrimp prefer soft, lower pH water and do best at slightly lower temperatures. These shrimp are sensitive to water quality so regular water changes and adequate filtration are important to keep them healthy and thriving.
