物种概述

Orange Shrimp, known in Asia as the Sunkist morph, is a bright tangerine selection of Neocaridina davidi bred from the same Taiwanese and Japanese lines that produced the red cherry. The orange grade is surprisingly recent — dedicated orange lines only stabilized in the early 2000s — and good specimens show a saturated, opaque orange over the entire body with no wild-type banding. It reaches 2-2.5 cm, grazes biofilm continuously, and shares the species' famous tolerance: 18-26 °C, pH 6.5-8.0 and moderate hardness all suit it. In the aquarium it is an active daytime cleaner that works moss, wood and leaf litter, and it breeds as readily as the red form — females carry 20-30 eggs and the young hatch as miniature adults. A group of ten or more will establish quickly; just keep colors separated, because all N. davidi morphs interbreed and mixed colonies drift back toward the wild brown form within a few generations.

原生生境

栖息地: Any stable freshwater community aquarium
水流: Gentle current
溶氧: Moderate oxygen

造景与硬件

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

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 — keep one color per tank for pure lines
Small peaceful community fish — Adults survive; provide moss for shrimplets
Otocinclus and small plecos — Peaceful algae crew with identical water needs
Freshwater snails — Complementary cleanup, no aggression
避免混养: Copper-based medications — Lethal to all invertebrates
Large-mouthed fish — Angelfish, gouramis and cichlids will eat shrimp
Different N. davidi colors — Cross-breeding produces drab wild-type offspring

繁殖与备注

雌雄差异: Females grow larger and deeper with a bright orange saddle visible before spawning; males are slimmer, smaller and noticeably paler.
繁殖方式: Breeds continuously in freshwater. The female molts, releases pheromones to attract males, then carries 20-30 orange-green eggs under her abdomen for roughly three weeks. Free-swimming larval stage absent — hatchlings are miniature adults feeding on biofilm and fine powder.
