Red Rili Shrimp

Red Rili Shrimp (Neocaridina davidi "Rili")

Striking red-and-transparent dwarf shrimp, perfect for planted aquariums

🐟 Quick Facts & Appearance

• Size: 1.5–2 cm (≈0.6–0.8 in); up to ~4 cm total body length in practice
• Lifespan: 1–2 years under stable conditions
• Temperament: Peaceful, non-aggressive scavengers 
• Females are larger and show opaque red patches or “saddles,” whereas males are smaller and less colorful

🌡️ Water Parameters & Setup

• Temperature: Optimal 22–26 °C (72–79 °F); range 18–30 °C acceptable
• pH: 6.0–8.0, with ideal range 6.5–7.5
• Hardness: GH ~4–8 dGH, KH 3–15 dKH
• Tank Size: 5 gallons (≈20 L) minimum; 20 L+ recommended for water stability
• Provide a well-cycled, planted tank (Java moss, leaf litter, algae surfaces), with plenty of hiding places and soft substrate. Avoid direct lighting and include driftwood or tubes

🥣 Diet & Feeding

• Omnivorous: Feeds on biofilm, algae, detritus, and shrimp-specific foods
• Supplement with blanched vegetables, algae wafers, and shrimp flakes/granules 
• Feed sparingly, once a day; remove uneaten food to maintain quality

🧪 Water Quality & Maintenance

• Extremely sensitive to ammonia and nitrite—both must be zero
• Nitrate should remain under 25 ppm; regular small changes (10–20% weekly) help maintain stable environment

🤝 Social Dynamics & Tankmates

• Best kept in groups of 8–10 or more—breeds readily with equal male/female ratio 
• Compatible with peaceful tankmates such as Corydoras, Amano shrimp, nerite snails, and small schooling fish—ensure there's no predation or competition for food
• Avoid fish likely to eat shrimp, and don’t mix color morphs to maintain strain purity
