Blue Bolt Shrimp - Caridina cantonensis : Complete Shrimp Profile & Care Guide

Table of contents

Introduction

Blue Bolt Shrimp (Caridina cantonensis) are a stunning addition to any aquarium. Not only are they visually appealing, but they also serve as an effective cleanup crew for the tank. Due to their striking colours and cleaning functions, they are one of the most sought-after ornamental species of freshwater invertebrates.

The cohabitation of Blue Bolt Shrimp with other Caridina variants is notably facilitated by their shared preference for a more acidic aquatic environment. Moreover, fostering interbreeding among distinct shrimp varieties can yield a diverse array of captivating hybrid offspring. While the integration of Blue Bolt Shrimp and Neocaridina species is plausible, the attainment of equilibrium conducive to the well-being of both shrimp categories poses a more intricate challenge.

In select instances, the inclusion of diminutive fish species, such as Neon Tetras, within a shrimp tank can be contemplated. However, an inherent concern lies in the potential predatorial perception of shrimp as a food source by the fish occupants. In this context, the provision of ample hiding locations assumes significance should such a cohabitating endeavour be undertaken. It is noteworthy that the vulnerability of juvenile shrimp to predation is notably heightened, warranting prudent consideration when contemplating the concurrent breeding of shrimp and the presence of fish within the same tank.

While these shrimp are not as hardy as their Neocaridina cousins, they can still thrive under the right conditions. It is important to maintain good water quality to ensure the health and longevity of these sensitive creatures. Additionally, providing them with plenty of hiding places and various surfaces to forage on will help them feel secure and comfortable in their environment. Plants like Java Moss can be an excellent addition to the tank and will be greatly appreciated by these shrimp. 

The most distinguishing feature of Blue Bolt Shrimp is the brilliant blue upper section of their dorsal shell, which gradually fades into a white body. The intensity and transparency of the blue can vary, and some individuals may have white spotting, particularly on the tail. These shrimp can also be graded based on their blue coverage and opacity, with higher grades commanding a higher price tag. Overall, Blue Bolt Shrimp are a beautiful and useful addition to any aquarium, provided that their specific needs are met.

Sexual Dimorphism

Determining the sex of Blue Bolt Shrimp can be challenging, as there are only subtle physical differences between males and females. Typically, female shrimp are larger and more rounded with a slightly larger tail, while males tend to be slimmer and smaller in size. One of the most distinctive features of a female Blue Bolt Shrimp is the saddle structure located on the upper body behind the head, which is used to store eggs before fertilization. These slight variations in physical characteristics provide helpful clues in identifying the gender of this species.

Natural Habitat

Blue Bolt Shrimp are a fascinating species that have been selectively bred to display stunning, bright blue colouration. Although these shrimp are not found in the wild, their natural counterpart, the Caridina Cantonensis, is abundant in various regions of Southern China and Northern Vietnam. In their natural habitat, Caridina Cantonensis prefers to inhabit mountain streams and creeks with clear, soft acidic water. These environments are often densely vegetated with fallen leaves and branches, creating a perfect shelter for the shrimp to thrive in.

Breeding

Blue Bolt Shrimp reach sexual maturity at approximately 3 to 4 months old. Before mating, females undergo a moulting process and release a pheromone into the surrounding water to attract males. The males will then become active and swim restlessly around the tank, searching for a mate.

The number of eggs laid by a female is proportional to her size. The eggs are carried under the female's tail and will hatch in about 4 to 5 weeks. During the incubation period, the female frequently tumbles the eggs with pleopods.

After hatching, the Blue Bolt female will release around 30 to 40 fully formed shrimplets, each measuring no more than 2 mm in length and resembling miniature replicas of the adult shrimp. The shrimplets' colour will intensify as they mature.

Diet & Feeding

Blue Bolt Shrimp are known to be scavengers and can easily find food on their own in a well-established aquarium. However, supplementing their diet with common shrimp foods such as algae wafers, along with treats like blanched vegetables and Alder Cones, can help improve their immune system and overall health. It is important to note that despite their ability to find food on their own, a well-balanced diet is crucial for Blue Bolt shrimp to thrive and breed successfully. Therefore, providing them with a variety of food options is recommended.
