ONYX SHRIMP (Neocaridina denticulata Var) Taiwan S grade

Red Onyx Shrimp (most commonly classified under the modern scientific name Neocaridina davidi, though historically associated with Neocaridina denticulata or Neocaridina heteropoda) is a striking, relatively new color morph highly prized in the freshwater aquarium hobby

Color Profile: Features a deep, rich maroon to chocolate-brown overlay

• Lighting Shifts: Appears almost completely black under low light, but reveals a glistening wine-red hue under high-quality aquarium lighting. [1, 2]
• Line Stability: Because it is a newer color strain, they require selective culling, as some offspring may still throw lighter chocolate or red shades
• These dwarf shrimp are beginner-friendly, exceptionally hardy, and adapt easily to conditioned tap water. [1, 2]

• pH Range: 6.8–7.5
• General Hardness (dGH): 6–15
• Carbonate Hardness (dKH): 0–10
• Total Dissolved Solids (TDS): 180–400

• Substrate: Use a dark substrate to dramatically maximize their color contrast and make their dark red tones pop.
• Environment: Provide plenty of live mosses, plants, and driftwood to host natural biofilm, which is their primary food source.
• Diet: Feed a balanced diet of high-quality shrimp pellets, algae wafers, and blanched vegetables.
• Safety Warning: Always ensure your aquarium is completely copper-free, as copper-based medications and heavy metals are highly toxic to all invertebrates
