Description

The Glass Bloodfin Tetra (Prionobrama filigera) is a freshwater characin from the Amazon River basin in South America. FishBase places it in the tetra family Characidae and records a maximum length of 6 cm. It is a generally peaceful, active, open-water fish for keepers who can provide a mature filtered aquarium, a proper group and uninterrupted swimming room.

Seriously Fish describes it as an excellent choice for beginners because it is relatively unfussy about water chemistry, food and companions. That suitability still depends on meeting its group, space and water-quality needs from the start. It is not a fish for a bowl, an unfiltered aquarium or a plan based on keeping a single specimen.

玻璃红鳍脂鲤（学名：*Prionobrama filigera*）是一种原产于南美洲亚马逊河流域的淡水脂鲤科鱼类。根据 FishBase 的分类，它属于脂鲤科（Characidae），最大体长可达 6 厘米。这种鱼性格温和、生性活跃，偏好在开阔水域游动；适合那些能够提供完善过滤系统、适宜群体规模以及充足游动空间的饲养者。

“Seriously Fish”网站指出，玻璃红鳍脂鲤是初学者的绝佳选择，因为它们对水质、食物和混养对象的要求相对宽松。当然，这种“适合性”的前提是必须从一开始就满足它们在群体规模、活动空间和水质方面的需求。它们绝不适合饲养在鱼缸（碗状容器）、缺乏过滤系统的水族箱中，也不适合以单条个体的方式进行饲养。
