Neocaridina davidi var. Rili

Variety of Red Cherry Shrimp · rili
📍 Southeast Asia
Rili Shrimp are a selectively bred Neocaridina davidi morph characterised by a two-tone pattern — a coloured head and tail section (typically red, orange, or blue) separated by a transparent or translucent mid-body section. This 'broken' coloration pattern is unique among neocaridina morphs and makes them visually striking in planted tanks. Care and breeding requirements are identical to standard red cherry shrimp.
Care Guide
Diet
Rili Shrimp are omnivores that primarily graze on biofilm and algae in the tank, supplemented with high-quality shrimp pellets 2-3 times weekly. Offer blanched vegetables like zucchini, spinach, and cucumber weekly to ensure balanced nutrition. Avoid overfeeding pellets, as uneaten food degrades water quality quickly.
Behavior
Rili Shrimp are peaceful, active foragers that spend most of their time grazing on surfaces and substrate. They are social and thrive in groups of 6 or more, displaying natural schooling behavior and reduced stress. Males may occasionally chase females during breeding season, but aggression is minimal.
Breeding
Rili Shrimp are prolific breeders in established tanks with stable parameters; females produce 20-30 shrimplets every 4-6 weeks without male intervention. Breeding occurs readily in captivity when water quality is maintained and adequate food is available. Keep Rili Shrimp separate from other Neocaridina morphs to prevent hybridization and maintain the distinctive two-tone coloration pattern.
Tank Mates
Similar water requirements and peaceful temperament; both are algae grazers
Peaceful bottom dweller; shares biofilm-grazing niche without competition
Small, peaceful fish that won't prey on adult shrimp; compatible water parameters
Peaceful and slow-moving; unlikely to harass shrimp in planted tanks
Algae-eating companion with identical care requirements and peaceful nature
Common Diseases
Bacterial Infection
Discoloration, white spots or patches on body, lethargy, loss of appetite
Perform 25% water changes daily, maintain pristine water quality, isolate affected shrimp if possible. Avoid antibiotics in community tanks; focus on improving conditions
Molting Problems
Difficulty shedding exoskeleton, shrimp stuck in molt, death shortly after molting
Ensure adequate calcium and minerals through mineral supplements or cuttlebone. Maintain stable water parameters and avoid sudden temperature fluctuations
Parasitic Infection
Excessive scratching on surfaces, visible parasites, lethargy, reduced feeding
Quarantine affected shrimp; perform frequent water changes. Salt baths (1-2 teaspoons per gallon for 10-15 minutes) may help; avoid copper-based treatments
Fatty Liver Disease
Lethargy, reduced reproduction, discoloration, poor molt quality
Reduce pellet feeding frequency, increase vegetable offerings, ensure varied diet with quality shrimp foods. Improve water quality and tank maintenance
