Blue Bolt Shrimp (Caridina cantonensis)

Blue Bolt Shrimps are a type of Taiwan Bee Shrimp. They are very good looking and are a fantastic cleanup crew for the tank. The combination of spectacular colours and cleaning functions makes them one of the most preferred ornamental species of freshwater invertebrates.

Blue Bolt Shrimp aren't as hardy as their Neocaridina cousins and can be sensitive to poor water conditions.

Like all Shrimp, Blue Bolts need plenty of hiding places in the aquarium to feel secure. They also like to have different kinds of surfaces to forage on. Plants like Java Moss will be much appreciated and are not difficult to grow and keep.

Blue Bolts are characterised by a brilliant blue upper section of the dorsal shell that gradually turns into a white body. The colouration of the dorsal shell can range from intense deep blue to light sky colour with varying transparency. You may also find these Shrimp with white spotting, especially on the tail.

Although Blue bolt shrimp do not have a complicated system of gradation, it still exists. Generally speaking, the more blue coverage with the more excellent opacity, the higher the grade is, and the bigger the price tag for the Shrimp.

Feeding Blue bolt shrimp is easy. Like all Shrimp, they are scavengers, and They will eat just about any food they manage to find in the tank. Therefore, in a well-established aquarium, they will often find enough supply of food from algae, decayed vegetation and biofilm by themselves.

However, this does not mean there is no need to feed them at all if you want them to thrive as well as breed. It would be ideal if you supplemented the Blue Bolts diet with common shrimp foods. Algae wafers are a favourite.

To add some variety to their diet, and improve their immune system, provide them with some Alder Cones or Indian Almond Leaves. They will greatly accept the odd treat of blanched vegetables such as lettuce, broccoli and spinach also.

Sexual Dimorphism

It is somewhat tricky to differentiate male from female Blue Bolts. Females tend to be bigger and more rounded with slightly larger tails and present a saddle structure on the upper body, behind the head, where eggs are stored before fertilisation. In contrast, males are slimmer and a little smaller than females.
