Cherry Shrimp (Neocaridina davidi) lifespan in home aquariums is 1-2 years on average. Factors that extend lifespan: stable water parameters (no daily swings), high-quality varied diet, peaceful tankmates, adequate tank size (minimum 5 gallons), and quarantine of new tankmates. Factors that shorten lifespan: water-quality crashes (ammonia spikes), aggressive tankmates, overcrowding, single-food diet, and chronic disease that goes untreated. Cherry Shrimp kept in mature established tanks (6+ months old) live closer to the upper end of the range; recently-set-up tanks see higher mortality. Captive-bred specimens typically outlive wild-caught counterparts because they were raised on aquarium parameters from juveniles.
