Family: Atyidae
Yellow (Golden) Shrimp — a lemon-yellow morph of Neocaridina davidi fixed from Taiwan lines around 2005. Reaches 2-2.5 cm, easy care at 18-26 °C, breeds freely in freshwater; shines against dark substrate and moss.
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.
Beginner-friendly. Extremely peaceful; groups of 10 or more.
Hold 18–26 °C and keep it stable — 18–26 °C stable range. Stable 18–26 °C; very tolerant of water chemistry.
Adults reach 2–2.5 cm; it is bottom — grazing plants and hardscape. Plan for at least 20 litres.
Algae and biofilm grazer; color foods keep hues intense. Feed two small meals a day rather than one large one.
Extremely peaceful; groups of 10 or more. Good company: 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. Keep away from 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.
Its home waters are Selective-bred form of the East Asian Neocaridina — any stable freshwater community aquarium, with gentle current.
In the aquarium: 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.. Females are larger and deeper-bodied with a visible yellow saddle; males are smaller, slimmer and paler lemon..
