Taxonomy and Habitat
Bloody Mary shrimp belong to the species Neocaridina davidi. They are a selectively bred color morph originating from wild populations found in freshwater streams and ponds in East Asia. Their natural habitat consists of slow-moving or stagnant waters with dense vegetation, which provides protection from predators and ample surfaces for biofilm growth.
Water Parameters
These shrimp are hardy and adapt well to various water conditions. They prefer a stable pH between 6.5 and 7.5. A temperature range of 18 to 25 degrees Celsius is considered optimal. Consistent water quality is essential, so regular partial water changes and proper filtration are necessary to maintain low nitrate levels.
Feeding and Nutrition
As scavengers, Bloody Mary shrimp are not picky eaters. They graze on biofilm, algae, and decaying plant matter. To ensure optimal health and coloration, supplement their diet with high-quality shrimp pellets, blanched vegetables, or specialized mineral foods. Christmas Moss provides an excellent surface for them to forage for microscopic food particles throughout the day.
Tank Mates
Due to their small size, they should be kept with peaceful tank mates. Small, non-aggressive fish like nano species are suitable, though some may predate on shrimplets. It is safest to keep them in a species-only tank or with other invertebrates like snails to ensure the highest survival rate for the offspring.
Molting and Breeding
Shrimp grow by molting their exoskeleton. During this time, they are vulnerable and require stable water parameters. Breeding is relatively straightforward; females carry eggs under their abdomen until they hatch into miniature versions of adults. No larval stage exists, making them easy to propagate in a well-planted aquarium with plenty of moss for the young to hide.
