Good fit for your tank?
Good fit for
- Mature planted aquarium setups
- Beginner shrimp keepers
- Peaceful nano aquariums
- Breeding colonies
Think carefully if
- The aquarium contains shrimp-eating fish
- The tank is newly cycled
- You want to preserve another Neocaridina colour line
- Water conditions change frequently
A Red Rili–type Neocaridina davidi line selected for a strongly pigmented red head and contrasting translucent body.
Appearance and Identification
Deep red head pigmentation with a paler or translucent central and rear body area; tail colour varies by line.
Red Head Rili is a trade pattern of Neocaridina davidi. Pattern boundaries and the amount of tail colour vary between breeders and individual shrimp.
Adult females are usually larger and deeper-bodied than males. Colour intensity alone is not a reliable sex indicator.

Use a mature, cycled aquarium with protected filter intakes, biofilm-rich surfaces, plants or mosses, and stable water chemistry.
Behaviour and Tankmates
Peaceful dwarf shrimp that spends much of its time grazing biofilm, algae, detritus, plants, and hardscape.
Best kept in a colony with other compatible Neocaridina sharing similar water requirements.
Not territorial.
Peaceful fish may still consume shrimplets. Different Neocaridina colour lines can interbreed, which may reduce colour consistency in later generations.
Water Parameters
Maintain stable, mineralized freshwater with sufficient calcium and magnesium. Mature biofilm and gradual acclimation improve survival.
Parameter caveat
Avoid rapid corrections to pH, hardness, temperature, or total dissolved solids.
Feeding
- Diet types
- Aufwuchs Grazer, Detritivore, Omnivore
- Feeding frequency
- Daily
- Preferred foods
- Mature biofilmCore natural grazing resource.
- Complete dwarf-shrimp foodFeed in small portions and remove excess.
- Leaf litterAdds grazing surface and slowly decomposing natural food.
Omnivorous biofilm grazer. Provide mature natural grazing surfaces plus small portions of complete shrimp food, algae-based foods, leaf litter, and occasional protein-rich food.
Avoid overfeeding. A mature aquarium with continuous grazing surfaces is more important than heavy feeding.
