The Crystal Black Shrimp shares its lineage and care requirements with the famous Crystal Red Shrimp, but displays bold alternating bands of deep, lustrous black and pure white rather than red. The contrast between the two colours is visually dramatic, and top-grade specimens with high white coverage — particularly the coveted SSS-grade animals with nearly full white bodies — are among the most prized invertebrates in the hobby.
Developed alongside the Crystal Red through selective breeding programs in Japan, the Crystal Black emerged as a parallel line celebrated for its unique monochrome aesthetic. The black pigmentation varies in depth and glossiness depending on lineage, with the finest specimens showing an almost velvet-like depth to their black bands.
Like all Caridina cantonensis variants, Crystal Black Shrimp are sensitive to water chemistry and require reverse osmosis water blended with Caridina-specific mineral salts to maintain the precise soft, acidic, low-KH conditions they need. They are active grazers that pick continuously at biofilm, decaying leaves, and fine organic matter. A mature, well-planted nano aquarium with active buffering substrate, stable parameters, and a sponge filter provides the ideal environment for this exquisite shrimp. Cross-breeding Crystal Black with Crystal Red produces a range of intermediate and mosaic-patterned offspring that are prized in their own right.
