科: Atyidae
绿晶虾是 Neocaridina davidi 的翠绿选育品系，源于 2000 年代末台湾育种线。成体 2–2.5 cm，18–26 °C 皮实好养，纯淡水繁殖容易；在绿莫斯与红草之间都极为上镜。
Green Jade Shrimp is the jade-green selection of Neocaridina davidi that emerged from Taiwanese breeding programs in the late 2000s, when breeders crossing yellow and wild-type lines noticed deep green sports and stabilized them into a true-breeding strain. Good green jades are a striking deep jade — almost emerald on the back, fading to a lighter mint on the underside — and unlike some color forms the green stays rich in adulthood. It is the same forgiving species underneath: 2-2.5 cm, comfortable at 18-26 °C across pH 6.5-8.0, unfussy about hardness, and constantly at work scraping algae from leaves, wood and glass. Green jade is among the best 'working' shrimp for a planted tank because its color reads beautifully against both green moss and red plants, and its transparent undertone gives it an almost metallic glow under good lighting. It breeds as easily as the red cherry — freshwater, no larval stage, monthly clutches — and tolerates the beginner mistakes that kill more delicate Caridina. Keep colors apart, avoid copper, and it will multiply for years.
饲养难度：容易。Extremely peaceful。
建议水温 18–26 °C，18–26 °C stable range；Stable 18–26 °C; very tolerant of water chemistry。
成体 2–2.5 cm 左右，因其Bottom — grazing plants and hardscape的习性，20 L 以上的缸更合适。
Algae and biofilm grazer; color foods keep hues intense。每天两小餐比一顿大餐更利于状态。
Extremely peaceful；Groups of 10 or more。理想混养对象：Other Neocaridina davidi morphs — Interbreed — single-color colonies only, Small tetras and rasboras — Safe for adults; moss shelters shrimplets, Otocinclus catfish — Peaceful, same water, same job。需避开Copper-based medications — Lethal to all invertebrates, Large predatory fish — Will eat shrimp, Plant fertilizers with trace copper — Copper accumulates and harms colonies。
产地为Selective-bred form of the East Asian Neocaridina，典型栖息地是Any stable freshwater community aquarium，对溶氧要求一般。
Breeds readily in pure freshwater. Females carry 15-25 eggs for roughly three weeks; hatchlings are fully formed and graze biofilm immediately. Monthly clutches are the norm in a mature tank.。Females are larger and deeper with a darker green saddle; males slimmer and paler mint.。
