物种概述

Chocolate Shrimp is the rich brown morph of Neocaridina davidi that Taiwan breeders stabilized in the early 2000s from darker wild-type individuals — the same foundation stock that later produced blue dream, black rose and other dark lines, which is why chocolate tanks occasionally surprise their owner with blue or black offspring. The best chocolates are a deep, warm, fully opaque brown, darker toward the back and tail, reading almost like tiny chestnuts moving over the substrate. As always with this species the care is simple: 2-2.5 cm of shrimp at 18-26 °C, pH anywhere from 6.5 to 8.0, moderate hardness, and a tank matured enough to grow the biofilm it grazes all day. It is an excellent choice for aquarists who find the bright cherry colors gaudy — the chocolate tone suits natural, wood-heavy biotope scapes. Breeding is the standard N. davidi routine: a three-week egg carry in freshwater, miniature hatchlings, no special feeding beyond fine powder in a mature system. Keep it away from other colors and it stays true.

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 dark Neocaridina lines — Blues and blacks descend from chocolate — expect sport offspring
Small peaceful community fish — Adults safe; moss for babies
Otocinclus catfish — Calm tankmate with identical needs
Freshwater snails — Peaceful scavenger companions
避免混养: Bright N. davidi colors — Crosses muddy both lines
Copper-based medications — Lethal to all invertebrates
Large-mouthed fish — Active shrimp hunters

繁殖与备注

雌雄差异: Females are deeper-bodied with a darker saddle; males smaller, slimmer and lighter brown.
繁殖方式: Standard N. davidi freshwater breeding — the female molts, mates, then fans 20-30 eggs for about three weeks. Because chocolate is a foundation dark line, some offspring emerge blue or black; breeders either cull or separate them.
