概述
银复齿脂鲤（Distichodus affinis）是一种活跃的非洲脂鲤，成长后鳍转鲜红，有些个体腹侧带粉色光泽。它会吃掉多数柔嫩绿植，因此比起精细草缸，更适合以沉木和光滑岩石为主的较大型群落。
分布与栖息地
见于刚果共和国及刚果民主共和国，在刚果河下游和中游利用多种生境。
饲养环境
至少约 120 × 30 × 30 cm。沙或砾石可作底床，沉木与光滑石块提供结构，并保留泳道和适量水流。
多数水草会被取食。若仍想尝试，可选水榕或蕨类等相对坚韧植物，但不是每尾鱼都会完全放过它们。
食性与喂食
本种杂食，能接受多数食物，植物性成分应占相当比例。可用红虫、水蚤等小型活饵或冷冻饵，配去皮豌豆、螺旋藻薄片及烫软菠菜，形成均衡菜单。
习性与混养
通常不具攻击性，但要按成鱼体形选择伙伴。可评估相容的较大型脂鲤、中型鲶鱼和温和慈鲷，同种也能群养。动作迟缓或长鳍鱼可能被轻咬，加入新缸友后需观察。
繁殖
野外有成大群在开阔水域产卵的记录，家庭繁殖过程则缺少详细资料。商业人工生产的说法带有不确定性，不能据此给出稳定可复制的方法。
补充说明
可靠的雌雄外部区别尚未知。红鳍、粉色腹侧等差异可能涉及外形相近的其他种，并非已证实的固定色型；辨认不宜只依色泽。

Overview
An active African characin, Distichodus affinis develops red fins with maturity, sometimes with a pinkish underside. Its tendency to consume greenery favors a larger wood-and-rock community over a delicate planted aquascape.
Distribution & habitat
It occurs in the Republic of the Congo and the Democratic Republic of the Congo, using varied environments across the lower and middle Congo basin.
Aquarium setup
Provide at least approximately 120 × 30 × 30 cm. Sand or gravel, smooth rocks, and wood can form the layout while preserving swimming room and some current.
Most soft vegetation is eaten. Tougher plants such as anubias and aquatic ferns may fare better, without guaranteeing protection from every individual.
Diet & feeding
This omnivore accepts many foods and needs a substantial vegetable component. Combine small live or frozen foods such as bloodworms and water fleas with shelled peas, algae-based flakes, and softened spinach.
Behaviour & compatibility
Usually nonaggressive, it still requires companions chosen for its adult size. Compatible larger characins, medium catfishes, and peaceful cichlids are possibilities. Conspecific groups can be maintained. Slow or long-finned neighbors may suffer nipping, so monitor new combinations.
Breeding
Wild fish spawn in large aggregations in open water, while a detailed home-aquarium procedure is lacking. Commercial production is reported tentatively and does not supply a reproducible method.
Notes
Reliable external sexing remains unknown. Variations such as a pink underside might involve similar species rather than established color forms. Color alone should not settle identification.
