The White Pearl Shrimp (also called white pearl shrimp) has a whitish transparent to slightly milky shell and dark eyes. The transparency of the shrimp’s carapace increases with age. A backstroke is often only hinted at in individual animals. Due to the transparency of the shrimp’s carapace, the eggs of the females shimmer through. These are snow white and resemble pearls, which led to the shrimp name. Females reach a size of up to three centimetres. They are a little fuller and larger than the males, which reach a size of up to 2.5 centimetres. The sexes can be easily distinguished. The females have a larger belly pocket and carry the eggs under the abdomen between the swimming legs.
The robust White Pearl Shrimp is well suited for beginners as it can cope with all common water temperatures. The optimum water temperature is 16 to 28 degrees Celsius. Other ideal water values are a total hardness of five to 20 dH, a carbonate hardness of two to 16 dH and a ph-value of 6 to 8. The pool water must not contain any copper or other heavy metals, as the White Pearl shrimp could react allergically and die. As this shrimp species is peaceful and extremely social, it is recommended that the animals only be kept in groups of at least ten conspecifics.
The shrimp aquarium should have a size of at least 20 litres. The White Pearl shrimp prefers a densely planted tank with hiding places and retreats through wood, stones or leaves. Foliage leaves also keep the aquarium water slightly acidic and prevent possible fungus. A dark substrate and many delicate aquatic plants not only ensure a good appearance in the shrimp aquarium, but also provide a healthy basis for the White Pearl Shrimp. Suitable aquatic plants are moss species (e.g. java moss, flaming moss, nymph) and ferns. A light current should also be present in the shrimp tank. Care should be taken to ensure that small shrimp cannot be sucked in. The so-called Hamburg filter mats for shrimp tanks have proven to be a good filter system. These are based on a centrifugal pump behind the filter mat.
As an omnivore, the White Pearl shrimp feeds not only on shrimp food that is specially adapted to their needs. Fish food with a high plant content is also accepted. The animal spends most of its time searching the substrate for food and thus absorbs detritus (decomposed organic substances), algae growth, microorganisms (e.g. bacteria, protozoa) and biofilm. Natural food such as leaves, alder cones or nettles are also used by the White Pearl Shrimp. Popular food sources are moss balls or hamburger filter mats on which microorganisms form. The use of powdered or fine-grained food has proven to be a good choice for rearing young shrimp.
The White Pearl Shrimp is uncomplicated and is considered to have a high reproductive capacity. It is easy to breed, because this is basically done without the breeder’s intervention. The development of the eggs can be easily observed in the females because of the transparent shrimp shell. Egg production starts in the neck area and is called spawning point or egg spot. If the eggs show black spots (eyes), offspring can be expected soon. Under optimal husbandry conditions, the females have 30 to 40 young several times a year after a gestation period of four to six weeks.
The one to two millimetre large young animals are fully developed and viable after hatching. They live in a group and do not require salt water for further development. Parents do not need to be separated from the young animals, as they are very peaceful among themselves. A transfer to a rearing tank is therefore not necessary. Since not all young animals reach adulthood, overpopulation in the shrimp tank is rare. It is possible to crossbreed the White Pearl shrimp with other bumblebee, bee or tiger shrimp. Crossbreeding with other shrimp species is usually not the breeding goal, as the White Pearl shrimp would lose its typical transparent shell colour.
The White Pearl shrimp can easily be kept in a tank together with other small peaceful fish species that do not stalk the animal, snails or mussels. The White Pearl Shrimp can also be socialised with other shrimp species in a tank. However, to prevent closely related shrimp species from crossing, it should be kept in a pure species tank or with another shrimp species (e.g. Caridina species).
