概述
红点短颌鮰脂鲤（Copeina guttata）来自亚马孙河中上游，体侧斑点是外观特色。它需要较长的鱼缸，充足遮蔽和稳定、洁净的水质比装饰风格更重要。
分布与栖息地
已知分布于巴西、秘鲁、厄瓜多尔和哥伦比亚的亚马孙河中上游水系。早期产地包括巴西亚马孙河沿线及内格罗河。
饲养环境
底面积至少约 120 × 30 cm。可用柔软细沙、沉木根枝和活体水草营造阴影，较深色的底床和丰富布置有助于表现体色。光照宜柔和，耐阴植物和少量浮水植物均可使用。
它不耐有机污染物积累，每周部分换水应成为常规。必须在生物过滤成熟、水质稳定后引入，不适合刚建立的新缸。
食性与喂食
野外可能主要在水面附近摄食昆虫，但这一食性仍属推测。缸内不难开口，可用优质薄片或颗粒搭配规律供应的红虫、水蚤、丰年虾等小型活饵或冷冻饵。部分干粮宜含植物或藻类成分，保持食谱多样有助于体况和体色。
雌雄区分
雄鱼通常颜色更鲜艳，鳍条延长也较明显。
繁殖
它似乎会将卵产在底床挖出的浅坑内，由雄鱼守护。这一描述尚有不确定性，不能当作已经详细验证的家庭繁殖流程。
补充说明
种名含“斑点”之意，与其体侧斑纹有关。本种属于脂鲤目下的短嘴脂鲤科，和常被统称为灯鱼的其他脂鲤类不能仅凭商品分类假定有相同繁殖方式。

Overview
The spotted flanks of Copeina guttata are a distinctive feature of this middle- and upper-Amazon fish. It needs a relatively long aquarium, ample cover, and consistently clean water; the exact decorative style is less important than those conditions.
Distribution & habitat
Known records span the middle and upper Amazon systems in Brazil, Peru, Ecuador, and Colombia. Early localities include sites along the Brazilian Amazon and the Rio Negro.
Aquarium setup
Allow a footprint of at least about 120 × 30 cm. Soft sand, roots and branches, and live plants can create shaded areas. Darker substrate and a well-furnished layout tend to enhance coloration. Keep lighting subdued, using shade-tolerant plants and some floating vegetation.
Organic pollutants must not accumulate. Make partial water changes part of weekly care, and introduce fish only after biological filtration and water conditions have stabilized.
Diet & feeding
Feeding on insects near the surface is suggested for wild fish rather than firmly documented. Captive individuals are readily fed, but benefit from variety. Combine quality flakes or granules with regular small live or frozen foods such as bloodworms, Daphnia, and Artemia. Include some prepared foods containing plant or algal ingredients.
Sexual dimorphism
Males generally develop stronger coloration and more extended fins.
Breeding
Eggs are apparently placed in a shallow excavated depression and guarded by the male. The account remains tentative and should not be treated as a fully established aquarium breeding procedure.
Notes
The species name refers to its spots. It belongs to Lebiasinidae within the characiform fishes; a broad tetra trade label should not be used to assume that its breeding behavior matches unrelated aquarium tetras.
