What Bloody Mary Shrimp look like
The Bloody Mary Shrimp (Neocaridina davidi var. Bloody Mary) exhibits a diminutive size, typically reaching a maximum adult length of 1 to 1.5 inches (2.5 to 3.8 cm). This species is characterized by its deep, translucent crimson body, which allows for a unique visibility of internal tissues and organs, contributing to its jewel-like appearance. Unlike the opaque red of Cherry shrimp, the Bloody Mary displays a more vibrant and glowing hue, resulting from the internal coloration. The shrimp's exoskeleton is smooth and devoid of significant ornamentation, although it features a well-defined carapace and elongated abdomen. The appendages, including the antennae and walking legs, are slender and proportionate, aiding in its agile movements. Notably, this species lacks pronounced sexual dimorphism, although females may exhibit a slightly larger size and a more rounded abdomen when carrying eggs. Defensive adaptations include the ability to blend into aquatic vegetation due to its coloration and a rapid escape response when threatened.
Behavior & temperament
Bloody Mary Shrimp are generally peaceful and exhibit a social nature, often found in small groups within their habitat. They are primarily benthic dwellers, foraging along the substrate for food, but can also be observed in the mid-water column during feeding times. This species is not an obligate schooler but benefits from the presence of conspecifics, which can help reduce stress and promote natural behaviors. Breeding occurs through a form of external fertilization, where females carry fertilized eggs under their pleopods until they hatch into miniature versions of adults. Their temperament is typically non-aggressive, making them suitable for community tanks, although they may exhibit territorial behaviors during breeding.
Diet & feeding
In the wild, Bloody Mary Shrimp are omnivorous scavengers, feeding on algae, detritus, and biofilm. In captivity, they require a varied diet that includes high-quality shrimp pellets, blanched vegetables, and occasional protein sources such as finely crushed fish flakes or live foods like daphnia.
