概述
鲁氏银板鱼（Metynnis lippincottianus）身体带斑点，有时与其他银板鱼共用商品名。它需要同种群体、开阔游动空间和丰富植物性食物，水草被啃是布景时必须考虑的特点。
分布与栖息地
确切范围仍不完全清楚，确认见于巴西亚马孙河中下游，至少上溯至马瑙斯，也见于巴西和法属圭亚那边界的奥亚波克河。亚马孙河口以南部分沿海水系记录似乎可信，其他较远流域的记录则可能涉及近似种。
自然环境包括植被茂密的支流，也会利用较急的水流地带。
饲养环境
成年群体至少需约 150 × 38 cm 底面积，缸长和宽度优先于高度。至少五条一起养，弱光及躲避区能帮助易紧张的鱼安定下来，同时提供适当水流。
活水草会被积极啃食，耐啃种类也可能要反复补种，可用柔软安全的仿真植物提供遮蔽。
食性与喂食
喂食应包含大量蔬菜，如黄瓜、西葫芦、豌豆、绿叶菜，配合藻片、螺旋藻或植物配方薄片。也会接受其他水族饲料，红虫和丰年虾可作为多样化补充。
习性与混养
通常适合与较大的温和鱼同养，特别小的鱼可能被摄食。银板类多使用中上层空间，较大、温和的底栖鲶鱼可作为不同水层的候选。
雌雄区分
雄鱼臀鳍较长，可能泛红。
补充说明
与没有明显体斑的常见银板鱼不同，本种带有斑点，但斑点通常不如斑点银板鱼（Metynnis maculatus）明显。相同的“斑点银板”贸易名称可能指不同种，应结合产地与外形确认。

Overview
Metynnis lippincottianus is a spotted silver dollar sometimes sold under names shared by other species. Conspecific company, open swimming space, and substantial vegetable feeding are important. Plant damage must be considered when planning decoration.
Distribution & habitat
The full range remains uncertain. Confirmed records include the middle and lower Amazon at least as far upstream as Manaus and the Oyapock on the Brazil–French Guiana border. Some coastal drainages south of the Amazon mouth appear to hold it, while reports from more distant systems may concern relatives.
Natural settings include densely vegetated tributaries and areas of relatively rapid water.
Aquarium setup
An adult group needs a footprint around 150 × 38 cm or more, prioritizing length and width over height. Keep at least five and provide dim light, sheltered areas, and a reasonable current.
Living plants are readily consumed. Even tough varieties may require repeated replacement, making soft, suitable artificial planting a possible source of cover.
Diet & feeding
Include generous amounts of vegetables such as cucumber, zucchini, peas, and greens, together with algae tablets, spirulina products, or vegetable flakes. Other aquarium foods are accepted too, with worms and brine shrimp adding variety.
Behaviour & compatibility
Larger peaceful fishes are generally suitable companions, whereas very small ones may be consumed. Silver dollars commonly use the middle and upper aquarium, leaving larger placid bottom-dwelling catfishes as possible candidates for the lower space.
Sexual dimorphism
Males have a more extended anal fin that may show a red tint.
Notes
Unlike commonly encountered unspotted silver dollars, this species has body spots, usually less conspicuous than those of Metynnis maculatus. The spotted silver dollar label can cover different species, so locality and appearance should both inform identification.
