Care

Diet

Green Rili Shrimp are detritivores that graze constantly on biofilm, algae, and decaying plant matter. Supplement with high-quality shrimp pellets (Shirakura, Mosura), blanched vegetables (zucchini, spinach, carrot), and occasional protein sources like dried seaweed or bloodworms to ensure optimal nutrition and coloration.

Behavior

These shrimp are active grazers that spend most of their time foraging on substrate and plants. They are social and thrive in groups, exhibiting natural molting cycles every 4-6 weeks where they shed their exoskeleton to grow. Colony dynamics are peaceful with minimal aggression, though males may compete for females during breeding season.

Breeding

Green Rili Shrimp breed readily in standard freshwater conditions without requiring special acidic water, making them excellent for beginners. Females produce 20-30 shrimplets per cycle, which are born fully-formed and independent. High survival rates occur in established tanks with adequate biofilm and hiding spaces.
