Orange Rili Shrimp
Neocaridina davidi 'Orange Rili'
Animalia›Arthropoda›Malacostraca›Atyidae
Variety of Red Cherry Shrimp · orange rili
📍 Southeast Asia
Orange Rili Shrimp display the characteristic Rili pattern — bright orange pigmentation on the head, carapace, and tail sections, with a clear transparent mid-section revealing the internal organs. This two-tone broken pattern is unique and visually distinctive against green plants and dark substrates. They are as easy to keep and breed as any other Neocaridina davidi colour morph and are a lively, active addition to planted nano tanks.
Care Guide
Diet
Orange Rili Shrimp are omnivores that primarily graze on biofilm and algae naturally present in established tanks. Supplement with high-quality shrimp pellets 2-3 times weekly and blanched vegetables like zucchini, spinach, and cucumber once weekly. They will also consume small amounts of decaying plant matter and leftover fish food.
Behavior
These shrimp are active foragers that spend most of their time exploring the substrate and plants in search of food. They are peaceful and social, thriving in groups of 6 or more where they exhibit natural schooling behavior. The distinctive orange and transparent Rili pattern makes them highly visible against planted backgrounds, and they are generally hardy and unafraid in established tanks.
Breeding
Orange Rili Shrimp are prolific breeders in captivity and will reproduce readily in stable conditions without special intervention. Females produce 20-30 shrimplets every 4-5 weeks; provide dense plants or moss for fry to hide and graze on biofilm. Keep this morph separate from other Neocaridina color variants to maintain the distinctive Rili pattern, as they will interbreed and dilute coloration.
Tank Mates
Similar water requirements and peaceful temperament; both are algae grazers that coexist well
Same genus but different color morph; will interbreed and produce hybrid offspring with diluted colors
Small, peaceful algae-eating fish that occupy different feeding zones and won't prey on shrimp
Tiny, peaceful fish that prefer similar warm water and planted environments; minimal predation risk
Peaceful algae grazer with no competition for food; both benefit from biofilm-rich environments
Essential plant that provides grazing surfaces, shelter for shrimplets, and biofilm growth
Common Diseases
Bacterial Infection
White spots or patches on body, cloudy appearance, lethargy, loss of appetite
Perform 25% water changes every 2-3 days; maintain pristine water quality with ammonia at 0 ppm and nitrate below 20 ppm; avoid antibiotics as they harm beneficial bacteria
Molting Issues
Difficulty shedding exoskeleton, incomplete molt, death shortly after molting
Ensure adequate calcium and minerals by using mineral-rich substrate or adding shrimp mineral supplements; maintain stable pH between 6.5-7.5 and proper hardness (6-20 dGH)
Parasitic Infection
Excessive scratching against objects, visible parasites on body, lethargy, reduced feeding
Perform frequent water changes; quarantine affected shrimp if possible; avoid copper-based treatments as they are toxic to shrimp; maintain excellent water quality
Sudden Death Syndrome
Rapid death with no visible symptoms, often after water changes or environmental stress
Acclimate shrimp slowly to new water (30+ minutes drip method); avoid sudden temperature or pH swings; use dechlorinated water and match parameters closely when doing water changes
