物种概述

Snowball Shrimp is the milky-white morph of Neocaridina zhangjiajiensis, a close relative of the cherry shrimp named after the sandstone scenery of Zhangjiajie in China's Hunan province, where the wild stock was first collected from cool, well-oxygenated hill streams. Taiwan breeders selected the palest wild individuals until the snowball line bred true — an opaque porcelain white that glows against dark aquasoil and green moss, one of the brightest-looking shrimp in the hobby. It grows slightly larger and stockier than N. davidi at up to 2.5-3 cm, and keeps the family's famous hardiness: 18-26 °C, pH 6.5-7.8, moderate hardness, and an easy-going appetite for algae, biofilm and standard shrimp foods. In the aquarium it is as active and visible as a red cherry and breeds with the same ease in pure freshwater — females carry a conspicuous snow-white clutch visible through the transparent underside. Because it is a different species from the davidi color morphs it will not hybridize with them, so it can share a tank with cherries without diluting either line.

性格食性与混养

群游性
Groups of 10 or more
食性
Algae and biofilm grazer; color foods are unnecessary
推荐混养
  • Neocaridina davidi color morphs — Different species — no hybrid risk, colors stay pure
  • Small peaceful community fish — Adults safe; moss for shrimplets
  • Otocinclus catfish — Gentle algae crew companion
  • Freshwater snails — Peaceful cleanup partners
避免混养
  • Copper-based medications — Lethal to all invertebrates
  • Large predatory fish — Shrimp are prey
  • High-temperature tanks above 27 °C — Shortens lifespan and fades the white

繁殖与备注

雌雄差异
Females are noticeably larger and stockier with a deeper, rounded abdomen; males are slim and almost glassy white.
繁殖方式
Breeds readily in pure freshwater. Females carry 20-30 creamy-white eggs for about three weeks; the white clutch shows clearly through the transparent swimmerets — a favorite sight in a mature tank. Hatchlings are miniature adults.

常见问题

雪球虾能和樱桃虾杂交吗?

不能——它们是不同物种(N. zhangjiajiensis 与 N. davidi)。两者能愉快共处,但不会杂交,所以两个品系都保持纯正。这让它成为混色虾缸里最安全的混养选择。

我的雪球为什么发黄?

一条黄色肠线通常只是透出的食物——正常,甚至是有用的健康信号。如果整个身体变黄,检查硝酸盐与温度;长期压力或高硝酸盐会让白色发闷。

雪球虾难养吗?

不难——与樱桃虾一样宽容,适应同样的宽水质区间,淡水繁殖同样高产。一个养熟的缸加基本的投喂纪律就是全部所需。

雪球虾能长多大?

比樱桃略大:营养良好的母虾 2.5–3 cm,身体明显更深;公虾保持纤细,约 2 cm。

什么底床最能衬托雪球虾?

深色——黑色水草泥、深色砾石或黑褐色细砂。浅底床上的白虾近乎隐形;深色底床上它们会发光。
