概述
黑带翘嘴脂鲤（Copella callolepis）是小型、偏上层活动的鱼，贸易中常被认成其他丝鳍脂鲤。虽然中文名带有“黑带”，本种实际缺少 Copella nattereri 那种明显的体侧暗带，鉴别应结合尾鳍标记和斑点颜色。
分布与栖息地
近期可靠记录来自巴西亚马孙河中部地区，早期模式地只写作亚马孙。由于长期与 Copella meinkeni 和 Copella nattereri 混淆，完整分布尚未厘清。
饲养环境
长期饲养的水面面积至少约 60 × 30 cm。密植缸或水陆缸较合适，浮水植物、沉木根枝及遮阴有助于营造柔和光照。它大部分时间在上层活动，应保留可用的水面区域。
干落叶可增加掩蔽，分解后形成的微生物还能补充鱼苗食物。保持溶氧，水面轻微扰动即可；它容易受水化学变化影响，应等过滤成熟、水质稳定后引入。
食性与喂食
天然食性可能以微小无脊椎动物和动物浮游生物为主。缸内可接受适口干粮，每日搭配丰年虾无节幼体、小型水蚤、白线虫等活饵或冷冻饵。小蟋蟀和果蝇也可投喂，先让昆虫摄入鱼粮或植物性食物，再喂鱼更合适。
习性与混养
性情温和，但不宜随意混入各种鱼组成的综合缸。可考虑体型相近的小型脂鲤、较小的底层鲶鱼及不捕食小鱼的矮小慈鲷，并核对环境需求。
建议雌雄混合至少 8～10 条，温和群游鱼也可增加安全感。雄鱼会相互展示以吸引雌鱼，在适当群体中能表现更好的体色和行为。
雌雄区分
雄鱼更大，鳍更延长、颜色更鲜艳；雌鱼通常较圆润，抱卵时尤其明显。
补充说明
本种曾被当作 Copella nattereri 的异名，后来恢复独立身份。与 Copella meinkeni 相比，本种尾鳍下叶有黑色三角形标记，体侧斑点为蓝黑至暗褐红色，而后者的斑点较鲜红；本种通常还有五六列斑点。商品标签可能沿用旧鉴定，不能据名称判断鱼的真实身份。

Overview
A small upper-level fish, Copella callolepis is regularly confused with other members of its genus in trade. It lacks the conspicuous flank stripe of Copella nattereri, while tail markings and spot color help separate it from other similar fishes.
Distribution & habitat
Recent confirmed records come from the central Brazilian Amazon. The original locality was recorded simply as Amazon, and a long history of confusion with Copella meinkeni and Copella nattereri leaves the full range unresolved.
Aquarium setup
Allow surface dimensions of at least about 60 × 30 cm for long-term care. Dense planting or a paludarium, floating vegetation, and shaded roots or branches create suitable subdued conditions. Much of its time is spent in the upper water, so retain usable surface space.
Dry leaves provide cover and support microorganisms that can supplement fry food. Maintain oxygen with gentle surface agitation. Avoid newly established systems, since changes in water chemistry can be problematic.
Diet & feeding
Tiny invertebrates and other zooplankton probably form the natural diet. Captive fish accept appropriate-sized preparations but should also receive daily small live or frozen foods such as Artemia nauplii, small water fleas, and grindal worms. Small crickets and fruit flies are suitable after being fed fish flakes or vegetable matter themselves.
Behaviour & compatibility
Although peaceful, it is not suitable for indiscriminate community housing. Consider similarly sized small characins, smaller bottom-dwelling catfishes, or diminutive nonpredatory cichlids where requirements match.
Keep at least eight to ten in a mixed-sex group. Peaceful schooling companions may improve confidence. Male competition for females brings out stronger colors and display behavior.
Sexual dimorphism
Males are larger, more colorful, and longer-finned. Females have a rounder body, particularly when carrying eggs.
Notes
Once treated as a synonym of Copella nattereri, this fish was later recognized separately. Compared with Copella meinkeni, it has a black triangular mark in the lower tail lobe and blue-black to dark brownish-red spots instead of vivid red ones, typically arranged in five or six rows. Old identifications persist in trade, so labels need checking against the fish itself.
