Why did my Rummy-Nose Tetras lose their red nose color?

Temporary fading after transport or water changes is normal stress and resolves within 24 hours. Persistent paleness warns of elevated ammonia/nitrite or unstable pH.

概述

红鼻剪刀（Hemigrammus rhodostomus）是群游性最整齐的灯科鱼，同时也是极佳的“水质监测鱼”：水质优良时头部鲜红，一旦水质波动或受惊红鼻便迅速褪色。

饲养

建议在80升以上长缸中群养10–15条以上，新鱼入缸务必采用滴流过水法。

投喂

小型灯鱼微颗粒、薄片、冻剑水蚤、水蚤及丰年虾。

繁殖

在极软弱酸水与昏暗光线下将卵散播于茂密的爪哇莫斯丛中。
