The Blue Bolt shrimp is easily distinguished from other shrimp by its bright blue colour. It belongs to the Taiwan Bees family and is a high breeding form. The Blue Bolts are often dyed completely blue. However, there are also specimens that are not completely dyed.
Mostly only the head shines in an intensive blue and the rest of the body appears whitish. Often the blue colouring of the shrimp increases with age and lighter blue becomes more intense. Blue Bolt shrimp grow up to three centimetres in size.
The keeping of the Blue Bolt is relatively uncomplicated and therefore it is also quite suitable for aquarium beginners. It feels most comfortable in soft water with a slightly acidic pH value, which should be below seven. By the way, alder cones are a good acid supplier. The total hardness of the water must have a value of four to ten, the carbon hardness a value of zero to six. Otherwise you should make sure that the shrimp find sufficient hiding places in the aquarium. Many plants, stones and wood are well suited to furnish the aquarium.
The shrimp love moss (for example coral, pearl or flame moss), as it is ideal for grazing. The peaceful shrimp do not like to be alone and feel particularly comfortable in groups of about ten animals. It should be possible to fill the aquarium with at least 20 litres of water. A heater is not necessary in the aquarium. However, care must be taken that the water temperature does not exceed 25 degrees Celsius. 21 to 23 degrees Celsius are optimal. There should be a water change of 10 to 30 percent per week.
Blue Bolt shrimp are not particularly choosy when it comes to food. They belong to the omnivores and can therefore be tasted a lot. In general, they should be fed a more vegetable diet. Plant sticks, for example, are a good option. Once or twice a week the diet can be supplemented with protein food. As a permanent food you can feed brown autumn leaves. Even cucumbers are gladly eaten by the Blue Bolts. However, you should not forget to remove the remains from the aquarium after 24 hours at the latest. Fish food should not be fed. Consequences of fish food can be irregularities during moulting or a higher mortality rate.
The breeding of the small shrimps is not particularly difficult as long as a few rules are observed. One of the basic requirements for breeding Blue Bolt shrimp is clean, germ-free water. If there are ten to twenty shrimp, it can be assumed that both males and females are present. They can be distinguished by their size: the females are usually slightly larger and more massive than the males. Blue Bolt shrimp are peaceful contemporaries. A separate breeding tank is therefore not necessary. The older animals normally do not attack the young and let them grow up in peace.
If the shrimp feel comfortable in their environment, they usually reproduce themselves. After fertilisation, the mother animal carries the eggs, which are approx. 1.3 millimetres in size, under the tail fan. The fanning provides the eggs with oxygen and prevents the formation of fungi. After three to four weeks about 20 to 40 fully developed young animals hatch. They can immediately start to feed themselves and are not dependent on the parent animals. A varied diet is important, especially during the growth phase of the young animals.
Blue Bolt shrimp, like most smaller shrimp species, are peaceful animals that can be well socialised. They can be kept together with smaller fish in the same aquarium. Only when breeding, you should use a separate tank, as fish could keep the small juveniles for food. If Blue Bolts share the tank with other Caridina species, crossbreeding may occur.
