Caridina cantonensis, commonly known as the bee shrimp, is a species of small freshwater shrimp popular in the aquarium hobby. Native to Taiwan and southern China, its vibrant and distinct coloration has been developed into many different ornamental varieties through selective breeding. Common varieties While the wild C. cantonensis is a muted, translucent sandy color, selective breeding has produced a stunning array of color patterns. Popular varieties include: Crystal Red and Crystal Black Shrimp: These are among the most famous varieties, featuring a red-and-white or black-and-white striped pattern. Higher grades of these shrimp have more intense, opaque white coloration and are more expensive. Golden Bee Shrimp: This variety has a white body with orangey-gold flesh that gives it a golden appearance. Blue Bolt and King Kong Shrimp: These are varieties of Taiwan Bee shrimp, appreciated for their intense blue and black coloration. Panda Shrimp: A bee shrimp variant with a black-and-white color pattern. Care requirements Caridina cantonensis is more sensitive to water conditions than some other dwarf shrimp species, such as Neocaridina, and is often recommended for intermediate to advanced aquarists. Water parameters: These shrimp thrive in soft, slightly acidic water, mimicking the mountain streams of their native habitat. Temperature: 62–76°F (16.5–24.5°C) is the ideal range. Stable temperatures are critical, as fluctuations can be fatal. pH: 5.8–7.4, depending on the specific variety. TDS: 100–200. Diet: Bee shrimp are omnivorous scavengers that feed on algae and biofilm. In an aquarium, their diet should be supplemented with high-quality shrimp pellets, blanched vegetables, and other foods. Uneaten food should be removed promptly to avoid water quality issues. Environment: A well-filtered, established tank is necessary. Many breeders prefer using sponge filters, as the gentle flow protects tiny shrimplets. Providing plenty of hiding places, such as live plants and botanicals like Indian almond leaves, will make them feel secure, especially when molting. Tankmates: Caridina cantonensis is a peaceful species. For breeding projects, they are often kept in species-only tanks to protect the young. Suitable tankmates are limited to non-aggressive species, such as snails or small, peaceful fish like pygmy corydoras. They can be kept with Neocaridina shrimp without the risk of cross-breeding. Breeding Breeding Caridina cantonensis is a key part of the hobby for many enthusiasts. Reproduction: Females are generally larger than males and carry eggs under their abdomen until they hatch. Tiny, miniature versions of the adults emerge from the eggs. Water quality: Stable water parameters are especially important for successful breeding and the survival of the young. Grading: As shrimp breeders work to produce specific color patterns, they select for certain traits. Grading systems are used to classify shrimp based on the intensity and distribution of their colors, with higher-grade shrimp being more valuable.
