概述
银飞凤（Semaprochilodus taeniurus）是一种需要宽敞环境的大型群游脂鲤，野外随季节在河流和洪泛区之间移动。会啃藻不等于只需靠缸内残余维生，食物中的植物部分和同种数量安排都需要认真考虑。
分布与栖息地
来自巴西亚马孙中部流域。在河道迁徙、产卵，主要到洪泛平原取食，也利用季节性湖泊与森林溪流。
饲养环境
成年至少参考 150 × 60 × 60 厘米，六尾以上的群体需要更大规模。装饰不苛刻，河砂、沉木枝条和树根即可。可保留自然藻供啃食，但柔软叶片会被吃，较硬水草也可能被啄，因此不是草缸的理想选择。
食性与喂食
杂食而以植物性食物为主，日常给焯软菠菜、生菜、黄瓜、西葫芦、藻片等，搭配优质干饲料及少量红虫等冷冻饵。野外还筛食有机碎屑，喂养应多样且足量，不要只等待缸里长藻。
习性与混养
同种只有少数几尾时容易攻击，群养应至少六尾并配足够大的缸；不具备条件时，可在适合的中大型温和鱼缸中单尾饲养。要结合鱼体与空间选择伙伴，而非只看它有吃藻功能。
雌雄区分
不易辨认雌雄，成熟雌鱼据称腹部较圆。
繁殖
水族箱繁殖尚未记录。野外雨季初从较贫营养的黑水、清水支流迁到湍急白水河段繁殖，受精卵漂流进入营养丰富的洪泛区，幼鱼在那里生长。
成鱼返回原来淹水森林支流取食三四个月后，雨季中段还会再次迁移，经主河和其他支流活动，直至水位下降；再涨水时，在当时所在支流口繁殖。较大、较老个体似乎可能停止迁徙，但没有确定年龄界限。
补充说明
与飞凤（Semaprochilodus insignis）相比，本种体侧暗斑终生保留，而近亲的幼鱼斑会逐渐消退。其双胃之一有泥，帮助处理天然摄入的食物，不能由此推断人工缸必须人为加入泥浆。

Overview
A large schooling characin, Semaprochilodus taeniurus moves seasonally between rivers and floodplain habitats. Its grazing behavior does not make aquarium leftovers an adequate diet. Plant-rich feeding and suitable conspecific stocking are central to care.
Distribution & habitat
It is native to the central Brazilian Amazon. River channels are used for migration and spawning, while floodplains, seasonal lakes, and forest streams provide feeding habitat.
Aquarium setup
Suggested adult housing starts at 150 by 60 by 60 cm, with substantially more space for a group. River sand, roots, and branches are sufficient. Retain some algae for grazing, but expect soft plants to be eaten and tougher leaves potentially sampled.
Diet & feeding
Although omnivorous, it primarily favors plant foods. Offer generous blanched greens, cucumber, zucchini, and algae wafers, supplemented with quality dry products and small frozen foods. Natural detritus feeding does not remove the need for a varied, deliberate aquarium diet.
Behaviour & compatibility
Small conspecific groups can be aggressive internally. Keep six or more in spacious housing, or one with compatible medium-to-large, nonaggressive fish. Select companions and facilities around adult size rather than a supposed algae-control role.
Sexual dimorphism
Sexing is difficult, although mature females reportedly have a rounder abdomen.
Breeding
Aquarium reproduction is unrecorded. Early wet-season migration carries fish from relatively nutrient-poor clear and black tributaries into turbulent white-water spawning areas. Eggs then drift into productive floodplains where young fish grow.
Adults return to their former flooded-forest tributary to feed for several months before another wet-season movement among rivers and tributaries. Renewed flooding brings another spawning phase. Older, larger fish may no longer migrate, without a defined age cutoff.
Notes
Flank spots remain throughout life, unlike the juvenile markings of Semaprochilodus insignis that fade with age. Mud in one of its two stomach compartments assists food processing; this anatomical feature is not an instruction to add mud to an aquarium.
