Black Crystal Bee Shrimp Care Guide - Setup, Feeding & Breeding

Black Crystal Bee Shrimp are small freshwater shrimp with a striking pattern of deep black and opaque white bands or patches across the body. Individual markings vary considerably, from broad blocks of black and white to more finely broken patterns, and high-grade specimens may have especially dense, snowy-white colouring.

These shrimp are peaceful, active invertebrates that spend much of their time grazing across leaves, wood, stones and other surfaces. They use their delicate walking legs and specialised mouthparts to pick at biofilm, algae and tiny edible particles, often becoming most visible when a group is exploring a new surface or gathering around food.

Their natural ancestors inhabit clear, soft, slightly acidic mountain streams and seepage habitats in southern China and nearby regions. These waters are typically cool, mineral-poor and well oxygenated, with a mixture of gravel, leaf litter, submerged wood and dense aquatic growth.

The black colour form is the result of careful selective breeding within the bee shrimp hobby. Like other ornamental Caridina, they are sensitive to sudden changes in water chemistry, but their attractive pattern, fascinating behaviour and small adult size make them a favourite for specialised planted shrimp aquariums.

Black Crystal Bee Shrimp are selectively bred aquarium shrimp from the bee shrimp lineage, which originates in southern China and Hong Kong in East Asia. The black-and-white forms seen in the hobby are captive-bred colour varieties rather than a distinct wild species.

A group should have at least a 20-litre aquarium, with a footprint of around 30 by 20 cm or larger and plenty of mature biological surface area. Use active buffering soil designed for bee shrimp, gentle filtration with a protected intake, and stable, soft, mineral-balanced water. Mosses, fine-leaved plants, driftwood, smooth stones, leaf litter and other textured decor provide grazing areas and shelter, while a mature, well-planted layout helps young shrimp survive.

Adults reach around 2.5 cm (1 inch) in length. Females are usually slightly larger and deeper-bodied than males.

Black Crystal Bee Shrimp graze naturally on biofilm, soft algae and microorganisms growing on aquarium surfaces. Supplement this with small amounts of quality shrimp granules or wafers, blanched vegetables such as spinach or courgette, and occasional protein-rich foods such as daphnia or specialised shrimp treats. Feed sparingly and remove uneaten food promptly, as excess food can quickly affect water quality in a small aquarium.

The safest companions are other peaceful dwarf shrimp, such as compatible Caridina varieties, and small, gentle snails including nerite, ramshorn and Malaysian trumpet snails. They can sometimes be kept with tiny, non-predatory fish such as chili rasboras, celestial pearl danios and otocinclus, although fish may eat newly hatched shrimplets. Avoid bettas, larger rasboras, cichlids, loaches, crayfish and other fish or invertebrates that can hunt adult shrimp or their young.

Black Crystal Bee Shrimp breed readily when settled in mature, stable aquariums. Females carry clusters of eggs beneath the abdomen, where they are fertilised and fanned until they hatch after roughly three to four weeks. The young emerge as fully formed miniature shrimp, so they need fine foods, biofilm and plenty of cover. There is no free-swimming larval stage, and the juveniles require no separate brackish-water phase.

Females are generally larger, broader through the abdomen and more rounded when carrying eggs. Males are smaller and slimmer, with a narrower abdomen; mature females may also show a visible saddle or developing eggs before spawning.
