🌿 Elite Biofilm Scavenger & 100% Plant-Safe Utility
Bloody Mary Shrimps are peaceful, non-stop organic cleaners that work around the clock to maintain pristine tank conditions. They actively graze across the substrate, hardscape, and plant leaves, consuming microscopic hair algae, organic biofilms, and leftover fish flakes before they can break down and compromise your water chemistry.
They are 100% safe for even the most delicate live aquarium plants, including soft carpet mosses, liverworts, and fine-leafed high-end flora. They will never damage healthy tissue; instead, they gently clean the leaves, helping your plants photosynthesize more efficiently. They breed readily in freshwater, allowing your customers to naturally establish a thriving, deep-red colony over time.

🛠️ Lighting, Temperature & Maintenance Guide
Lighting Requirements: Highly Adaptable. They do not require specialized lighting for health. However, a high-quality full-spectrum LED light will make their deep, translucent wine-red bodies pop with unparalleled brilliance, especially when contrasted against dark aquascaping soil and bright green mosses.
Temperature Parameters: Prefers a stable temperature range of 18°C – 26°C (64°F – 78°F). While they can tolerate minor fluctuations, keeping them in a stable environment ensures optimal breeding success and long-term health.
Water Chemistry & Molting Health: Requires a pH range of 6.5 – 8.0, with a preferred gH of 6–8 and kH of 2–5. Providing adequate mineral content (TDS around 150–250) is essential to supply the necessary calcium for safe, successful molting, preventing the dangerous "white ring of death" structural failures.
Tankmates & Predation Caution: Due to their small size, they are best kept in specialized shrimp tanks or with very peaceful, tiny tankmates such as small snails, Otocinclus, or micro-rasboras. Large or aggressive fish will easily view them—especially their young fry—as a food source.
