種の概要

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.

原生環境

生息地: Any stable freshwater community aquarium
水流: Gentle current
溶存酸素: Moderate oxygen

レイアウトと設備

底床: Fine inert gravel or shrimp-safe sand
流木・石組: Java moss and driftwood for grazing
水草: Dense moss and fine-leaf plants

性格・餌・混泳

群泳性: Groups of 10 or more
餌: Algae and biofilm grazer; color foods keep hues intense
おすすめの混泳相手: 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
混泳しないほうがいい相手: 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

繁殖と注意点

雌雄の違い: Females are larger and deeper-bodied with a visible yellow saddle; males are smaller, slimmer and paler lemon.
繁殖方法: 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.
