Quick Overview of the Blue Diamond Neocaridina Shrimp
The Blue Diamond Neocaridina Shrimp (Neocaridina davidi var. “Blue Diamond”) is an elite, selectively bred dwarf shrimp strain derived from high-grade Chocolate and Carbon Rili lines. Reaching a compact adult size of 1 to 1.5 inches (2.5 to 3.8 cm), this high-grade line stands out for its exceptionally dark, opaque pigmentation—ranging from deep sapphire navy to a glittering midnight blue. Unlike lighter blue velvet or translucent sky-blue morphs, Blue Diamonds possess deep, solid coverage across their entire body, including legs and tail. Endlessly active and completely peaceful, a colony of these dwarf shrimp brings continuous motion and utility to any nano layout.

Local Care Tips for Bacolod Aquarists
Bacolod Tap Water Synergy & Molting Health: Blue Diamond Neocaridina shrimp are remarkably resilient and thrive in Bacolod’s typical neutral-to-slightly-hard, mineral-rich tap water (pH 7.0–7.8). Dissolved minerals like calcium and magnesium in local water provide essential GH/KH levels needed for healthy exoskeleton molting. Simply treat your tap water with a high-grade dechlorinator during weekly maintenance. Never use copper-based plant fertilizers or treatments, as copper is lethal to all freshwater invertebrates.
Aquascaping Strategy & High-Contrast Plant Layout: Because of their deep navy bodies, Blue Diamonds look most spectacular grazing on bright green carpets like Monte Carlo or Dwarf Hairgrass, or positioned against lighter sand substrates. Incorporate fine-leaved mosses (such as Java Moss or Christmas Moss) into your hardscape; moss provides rich surface area for micro-biofilm growth, which feeds both adults and tiny shrimplets. Frame your midground with easy epiphytes like Anubias Nano, Java Ferns, or Bucephalandra bound to local driftwood or Seiryu stones—just ensure the rhizomes of these epiphytes remain completely exposed above the soil to keep them from rotting!
Dietary Specifics & Tankmate Compatibility: Blue Diamonds are dedicated cleanup workers that graze continuously on algae, detritus, and decaying plant matter. Supplement their diet daily with high-quality sinking shrimp pellets, spirulina powder, mineral blocks, and occasional treats of blanched spinach or cucumber. They possess zero aggression and can be safely housed alongside other dwarf shrimp, Horned Nerite Snails, Otocinclus, Pygmy Corydoras, and small micro-schoolers (like Chili Rasboras or Green Axelrodi Rasboras). Keep a secure mesh screen over filter intakes to protect tiny shrimplets from getting pulled into the pump!
