Species: Bloody Mary Shrimp (Neocaridina davidi)
Bloody Mary Shrimp are a striking, high-grade freshwater shrimp known for their deep, translucent red coloration that appears almost glowing under aquarium lighting. Unlike Fire Red varieties, their color comes from within the body rather than a solid outer shell, giving them a unique, rich appearance. Hardy and easy to care for, they are an excellent choice for both beginners and advanced shrimp keepers.
Bloody Mary Shrimp are a selectively bred variant of Neocaridina davidi, prized for their dark red, wine-like coloration and slightly translucent body. This gives them a glossy, almost luminous look compared to other red shrimp varieties. They are active scavengers, constantly grazing on biofilm, algae, and leftover food, making them both beautiful and beneficial to the aquarium ecosystem. They thrive best in planted tanks with plenty of natural surfaces to explore.

Bloody Mary Shrimp are peaceful and thrive in colonies, where they feel secure and display natural behaviors. They spend most of their time grazing on plants, substrate, and décor. Best kept with small, non-aggressive tank mates or in shrimp-only setups. Avoid larger or predatory fish, as their coloration can make them more visible and vulnerable.
Bloody Mary Shrimp breed readily in stable freshwater aquariums. Offspring may vary slightly in coloration, and selective breeding can help maintain the deep red line. Their color often appears most vibrant under proper lighting and against darker substrates. Like all shrimp, they are sensitive to copper, ammonia, and sudden changes in water parameters, so stable conditions are key to long-term success.
