Blue Jelly Shrimp - Neocaridina davidi : Complete Shrimp Profile & Care Guide
Table of contents
Introduction
The Blue Jelly Shrimp (Neocaridina davidi) is a result of selective breeding efforts involving the Blue Rili Shrimp. This intentional breeding has produced a unique colouration in the Blue Jelly Shrimp, setting them apart from other species of Dwarf Shrimp. Their striking appearance makes them an excellent addition to a peaceful tropical community aquarium, where they contribute to an exceptional visual display.
Beyond their eye-catching aesthetics, Blue Jelly Shrimp possess the desirable traits of hardiness and prolific breeding commonly observed in Neocaridina shrimp. While not as widely recognized as some other Neocaridina species, these shrimp are still an excellent choice for beginners in the aquarium hobby due to their ease of care and breeding.
For optimal social dynamics, keeping a minimum of 10 Blue Jelly Shrimp in a tank is recommended, as they are highly social creatures. Increasing their numbers promotes confidence and reduces stress within the group. Blue Jelly Shrimp exhibit amiable and undemanding behaviour, posing no threat to other aquarium inhabitants. They coexist harmoniously with various species, including other freshwater shrimp, tropical fish that do not prey on shrimp, and different types of snails.
Notably, the colouration of Blue Jelly Shrimp can vary, with shades of blue and occasionally red spots appearing on the extremities, especially in offspring bred from Blue Rili Shrimp. It is worth noting that the diet of these shrimp can influence their colour, with certain foods like spinach temporarily causing a greenish hue. Consequently, individual variations, including subtle green tints, can manifest among Blue Jelly Shrimp specimens.

Sexual Dimorphism
Distinguishing between male and female Blue Jelly Shrimp is relatively straightforward, setting them apart from certain other shrimp species. Females can be identified by their larger size compared to males, and they possess a distinct saddle and a curved underbelly that is readily visible to the naked eye. Additionally, it is noteworthy that males exhibit a lesser amount of white colouration in comparison to their female counterparts. This characteristic sexual dimorphism allows for a clear differentiation between the genders of Blue Jelly Shrimp.

Natural Habitat
Blue Jelly Shrimp are the product of selective breeding, resulting in a distinct and unique variety of shrimp. Due to their selective breeding origins, Blue Jelly Shrimp do not have a natural wild habitat. Instead, they have been selectively bred and cultivated in aquariums by dedicated enthusiasts and breeders. This selective breeding has resulted in their striking blue colouration, making them a sought-after addition to freshwater aquariums.
Breeding
The breeding process of Blue Jelly shrimp is characterized by remarkable ease. These shrimp typically reach sexual maturity between 2 and 3 months of age. The females carry a clutch of yellowish eggs under their tails. By maintaining a healthy ratio of females to males, aquarists can cultivate large colonies of these shrimp. Once introduced to the aquarium, Blue Jelly shrimp exhibit prolific breeding behaviour.
A notable characteristic of the breeding cycle is the visibility of shrimplets' eyes through their translucent eggshells a few days prior to hatching. The light colouration of the eggs facilitates this observation. Each female releases an impressive quantity of approximately 30 to 50 shrimplets every 5 to 6 weeks, contributing to population growth. However, it is worth mentioning that shrimp in their early developmental stage lack distinct colouration, which can lead to challenges in their detection by aquarists.
Diet & Feeding
Blue Jelly Shrimp, like other shrimp species, exhibit a bottom-feeding behaviour and possess a versatile diet, consuming a wide range of food sources. While their preferred sustenance is a biofilm, which may be insufficient in well-maintained aquariums, it becomes necessary to supplement their diet with high-quality dried fish or shrimp food. Additionally, these shrimp will greatly appreciate the inclusion of blanched vegetable treats such as courgette, broccoli, zucchini, and cucumber, which offer both nutritional value and variety. Furthermore, the provision of dried leaves, such as Indian Almond leaves or Mulberry leaves, can be beneficial for the well-being of Blue Jelly Shrimp.
