Discover the Bloody Mary Shrimp (Neocaridina davidi)—a captivating red dwarf shrimp renowned for its deep, uniform wine-red body that doesn’t fade like pigment-based varieties. Native to selective breeding programs in Taiwan from Chocolate Sakura lines, these peaceful omnivores reach 1-1.2 inches (2.5-3 cm), with females slightly larger and more colorful. Ideal for nano or community tanks, they graze on biofilm, algae precursors, and detritus, helping maintain a clean environment without aggressive algae-eating.​

Beginner Setup Guide

Start with a 10+ gallon tank filtered for gentle flow, filled with live plants like Java moss, Anubias, or Cryptocoryne for hiding and grazing surfaces. Use dark substrate to enhance their vivid red against a natural backdrop—see their glow in this setup [image from depicting Bloody Marys in a low-maintenance planted tank]. Add leaf litter (e.g., alder cones or oak leaves) for natural biofilm, and perform 10-15% weekly water changes to mimic stable stream conditions. Avoid copper medications, as they are toxic to all shrimp.​​

Feeding Essentials

These scavengers thrive primarily on tank detritus but benefit from 2-3 weekly supplemental feedings of shrimp pellets, blanched veggies (zucchini, spinach), or astaxanthin-rich foods to boost red intensity. Feed sparingly—remove uneaten portions after 2 hours to prevent water fouling. Healthy adults live 18-24 months, with females producing 20-40 live young every 4-6 weeks after a 3-4 week gestation.​

Breeding and Compatibility

Breeding occurs effortlessly in optimal parameters; separate weaker offspring to maintain pure red lines. House with peaceful tank mates like small fish (e.g., Otocinclus), snails, or other Neocaridina—minimum group of 10 reduces stress and enhances coloration. Their wide tolerance makes them forgiving for novices.​
