Important data
Product description & details
The Red Crystal Shrimp, Caridina logemanni, is a popular form of beekeeping. The wild form of Caridina logemanni comes from China and occurs in small mountain streams that have very soft, cool and oxygen-rich water. The transparent body of the Red Crystal is covered in bright red pigments, which often form vertical stripes. It is assigned to grades B to C (K0, K2), so it has no uniform red bands and only a few white color pigments. The Red Bee, which is marked with uniform red and white bands, was bred from it through years of selection.
Care in the aquarium
Caridina logemanni one of the more demanding shrimp species, which depends primarily on soft water and water values that are as stable as possible. Keeping this beautiful shrimp is possible in aquariums with a capacity of 10 liters or more, but since the water values fluctuate significantly less with more volume, we recommend an aquarium that holds 20 liters or more. The Red Crystal needs clean, oxygen-rich, soft and lime-free water (GH 3-8, CH 0-3), which is why it is best kept on re-mineralized osmosis water. The Bee Shrimp Mineral GH+ is suitable as a mineral salt. We recommend active soil as substrate, such as Ebi Gold Shrimp Soil, which sets and maintains the correct water parameters. It is also important that the temperature of the water does not exceed 25°C for long periods of time, even in summer. In order for this sociable dwarf shrimp to feel safe, it should be kept in a group of at least 10 animals and in a well-planted aquarium. The plants, but also wood, stone structures or shrimp tubes offer it protection and places of retreat. Ideally, the Red Crystal is kept in a pure shrimp aquarium, possibly with snails. It is possible to socialize with small fish that do not chase it, but loss of shrimplets is to be expected.
Feeding
As a classic leftover recycler, the Red Crystal feeds on biofilm and algae growth as well as detritus (dead plant material, carrion, leftover food). In the aquarium it can be fed with special types of shrimp food, leaves, algae powder and occasionally frozen food. Ideally, there are always brown autumn leaves in the aquarium, which represent optimal permanent food for the animals.
Sexual characteristics and breeding
Sex determination is usually not possible in young animals, but only in sexually mature animals. Juveniles and males have a narrower underside of the abdomen, while sexually mature females have a wider underside that covers the swimming legs like a “skirt”. This widening of the abdomen serves to protect the eggs, which the female carries and cares between her swimming legs until they hatch. As with most dwarf shrimp, female Red Crystal adults are slightly larger than males. Caridina logemanni reproduces in fresh water and can be bred in an aquarium without any problems as long as the water parameters are right. After a gestation period of around 3 to 4 weeks, the female releases around 10-30 fully developed shrimplets, which initially feed on microorganisms present in the aquarium and can be fed with dust food.
