Bee Shrimp (Crystal Red / Black)

The Bee Shrimp (Crystal Red / Black), scientifically known as Caridina cantonensis, belongs to the Invertebrates family group. Adults reach a maximum size of approximately 3 cm and have a fusiform body shape with a moderate growth rate. Classified as peaceful, this species primarily occupies the bottom and mid-level zones of the aquarium and produces a low level of biological waste.

To thrive, the Bee Shrimp (Crystal Red / Black) requires a freshwater only aquarium with a minimum volume of 19 litres and a tank length of at least 30 cm. Water temperature should be maintained between 18°C and 24°C, with a pH range of 5.5–6.8 and a general hardness of 3–6 dGH. A low water flow is preferred.

Due to its specialist needs, the Bee Shrimp (Crystal Red / Black) is best suited for fishkeepers who can provide a carefully planned setup. This species is available in 4 varieties: Crystal Red (CRS), Crystal Black (CBS), Taiwan Bee / Shadow, and Tiger Shrimp. Each may differ slightly in size, temperament, or care needs, so it is worth checking the specific requirements of the variety you plan to keep.

When setting up an aquarium for the Bee Shrimp (Crystal Red / Black), a low water flow best suits their natural preferences. Because this species occupies the bottom and mid-level zones, the aquarium layout should prioritise open swimming space in the centre of the tank for free movement and sufficient floor space with hiding spots among rocks, wood, or dense planting. Useful additions include a nutrient-rich soil substrate to support planted setups, driftwood, which can serve as both a hiding place and a dietary supplement, leaf litter or blackwater tannins to replicate their natural soft-water habitat, an established tank with natural algae growth, as they depend on it as a primary food source, and dense planting to provide cover, break sightlines, and reduce stress.

Classified as peaceful, the Bee Shrimp (Crystal Red / Black) is a schooling species that feels most secure in a sizeable group, where natural shoaling behaviour reduces stress and brings out their best colours. Selecting tankmates that favour different water layers from the bottom and mid-level zones can help reduce competition and territorial overlap.

Bee Shrimp (Crystal Red / Black) is best for a fishkeeper who wants a species that can settle into a calmer community setup and can provide a keeper who can commit to a proper group of at least 10. It makes the most sense for a hobbyist who will actually build around its needs, especially soil / nutrient rich.

The most common mistake is buying Bee Shrimp (Crystal Red / Black) for looks first and only later discovering how its adult size, behavior, or bioload changes the whole tank plan. Another frequent problem is underestimating its social needs. A token pair or trio often behaves very differently from a real group.
