🦐 Characteristics
Bright orange coloration with a clear midsection (classic “Rili” pattern).
Peaceful, active, and great algae cleaners.
Small in size but very eye-catching in planted tanks.
Easy to breed in aquariums if water is stable.
🍽️ Food
Type: Omnivorous scavenger
Diet: Algae, biofilm, shrimp pellets, blanched veggies (spinach, zucchini, cucumber), algae wafers.
Feeding: Small amounts, 3–4 times per week (they mostly graze naturally).
🛠️ Maintenance
Tank Size: Minimum 10 gallons (for a colony).
Filtration: Gentle sponge filter (to avoid sucking shrimplets).
Decor: Planted tanks with moss, driftwood, and hiding spots.
Water Change: 20–30% weekly with dechlorinated water.
👥 Social Behavior
Minimum Group Size: At least 10+ shrimp (they feel safer and breed better).
Tank Mates: Peaceful nano fish (neon tetras, rasboras, endlers, otocinclus) & other Neocaridina shrimp.
Avoid: Aggressive or large fish (cichlids, bettas, goldfish) – they may eat shrimp.
✅ Do’s
Provide plenty of plants and moss for grazing & hiding.
Keep stable water parameters (shrimp are sensitive to swings).
Acclimate slowly when introducing to a new tank.
❌ Don’ts
Don’t keep with predator fish.
Don’t use copper-based medications (toxic to shrimp).
Don’t overfeed – uneaten food fouls the water quickly.
⭐ Quick Tips
Great for beginners in shrimp keeping.
Very hardy compared to other shrimp types.
Their unique orange + clear body pattern makes them a stunning addition to planted aquariums.
