Descripción de la especie

Rili Shrimp is the piebald pattern morph of Neocaridina davidi created in Japan and Taiwan by selecting cherry shrimp with transparent mid-sections until the color broke into clean patches — the name comes from the Japanese painting technique 'rili-zu', a mottled ink style. A classic red rili wears solid cherry red on the head and tail with a glass-clear band between, so the internal organs show as a dark line along the back; blue, orange and yellow rilis follow the same broken pattern. Beneath the fancy coat it is the indestructible N. davidi: 2-2.5 cm, 18-26 °C, broad water chemistry tolerance, and a relentless appetite for algae. In the aquarium rilis are among the most entertaining neocaridinas — the transparent window makes their feeding and egg fanning visible in a way solid-color shrimp never allow. They breed freely in freshwater, though rili patterning throws a range of grades from almost-clear to nearly-solid, and dedicated breeders select the crisp high-contrast patches each generation. Keep one pattern per tank and they will color up within months.

Compañeros recomendados

• Other Neocaridina davidi morphs — Interbreed; rili pattern degrades fastest in mixed tanks
• Small rasboras and tetras — Adults safe; dense moss for shrimplets
• Otocinclus catfish — Peaceful algae partner
• Freshwater snails — No conflicts

Evitar con

• Copper-based medications — Lethal to all invertebrates
• Other color/pattern N. davidi — Mixing erodes the crisp piebald pattern
• Predatory fish — Shrimp are prey

Cría y notas

Dimorfismo sexual

Females are larger and deeper-bodied, the transparent window making the green egg mass easy to watch; males slimmer with sharper red patches.

Método de cría

Breeds freely in freshwater like the species. Clutches of 20-30 eggs hatch after ~3 weeks as miniature adults; expect a spread of rili grades in each batch, and select high-contrast juveniles if you want show-quality lines.
