黄金米虾 (Neocaridina davidi)

科: Atyidae

黄金米虾是 Neocaridina davidi 的柠檬黄选育品系，约 2005 年由台湾育种线固定成系。成体 2–2.5 cm，18–26 °C 易养，纯淡水即可繁殖；在深色底床与绿莫斯映衬下格外亮眼。

物种概述

Yellow Shrimp, often sold as Golden Shrimp, is a sunny lemon-yellow morph of Neocaridina davidi developed from yellow-gene sports that appeared in Taiwan breeder lines around 2005 and were then fixed into a stable, uniformly yellow strain. Unlike the red and orange forms, yellow individuals keep a clean color with little wild-type banding even in lower grades, because the yellow pigment masks the underlying pattern. It grows to 2-2.5 cm and shows exactly the same easy disposition as every other N. davidi morph: 18-26 °C, pH 6.5-8.0, moderate hardness, and a strong appetite for algae and biofilm. It is a lively, visible daytime grazer that stands out beautifully against dark substrate and green moss. Breeding is straightforward in freshwater — females carry a modest clutch of 15-25 eggs and the fry appear as tiny replicas of the parents. Keep a single color per tank, since all N. davidi morphs hybridize freely and mixed colonies lose their color within a few generations.

性格食性与混养

群游性
Groups of 10 or more
食性
Algae and biofilm grazer; color foods keep hues intense
推荐混养
  • Other Neocaridina davidi morphs — Interbreed — one color per tank
  • Small tetras, rasboras and danios — Ignore adults; moss protects shrimplets
  • Otocinclus catfish — Ideal calm algae-eating partner
  • Freshwater snails — Share cleanup duties peacefully
避免混养
  • Copper-based medications — Lethal to all invertebrates
  • Large predatory fish — Cichlids and big gouramis eat shrimp
  • Other N. davidi colors — Cross-breeding erodes the yellow line

繁殖与备注

雌雄差异
Females are larger and deeper-bodied with a visible yellow saddle; males are smaller, slimmer and paler lemon.
繁殖方式
Breeds readily in pure freshwater. After a molt the female releases pheromones, mates, then carries 15-25 yellow-green eggs for about three weeks. Hatchlings are miniature adults; a mature moss-filled tank yields a steady supply of juveniles.
