概述
'Puntius' snyderi 是与近似种外形很接近的小型鲤科鱼，天然体色偏绿，体侧带深色斑纹。最有用的外部识别线索是须极小、不明显，有些个体甚至看不到，不能只靠“金色鲃鱼”类商品名区分。
分布与栖息地
见于中国台湾中北部，也有中国大陆记录；大陆个体在部分旧记载中仍使用近似种名称。
偏好缓流溪流、灌溉渠和池塘的浅水岸边，水草或岸边植被茂盛的地点较常见。
饲养环境
缸底至少约 90 × 30 cm，密植和深色底床有助于显色。浮水植物、沉木根和枝条可柔化光线并增加环境结构。
过滤不必很强，保留一定水流即可，也能适应有流水的溪流式布景，不应把这一点理解为必须制造激流。
食性与喂食
自然杂食，摄取底部硅藻、其他藻类、有机碎屑、小昆虫、虫、甲壳类与其他浮游动物。缸内一般容易喂养，以活或冷冻红虫、水蚤、丰年虾搭配优质薄片或颗粒，部分干粮应含植物或藻类成分。
习性与混养
表现较和平，适合条件相近、体形相仿的温和伙伴。至少 8～10 条、雌雄混合的群体更合适，其他合适群游鱼也可增加安全感。雄鱼竞争雌鱼与群内位置时会展现较好的体色。
雌雄区分
成年雌鱼腹部更圆，通常也略大；成熟雄鱼身体下部会出现红色。
补充说明
与 'Puntius' semifasciolatus 的野生型相比，本种须微小或缺失，身体较高，主要深色竖斑约 4～5 处；近似种须较明显，身体较修长，主要斑纹约 7～9 处。
两者不能简单视为同一鱼的不同体色。属名前的引号保留了这组鱼历史上分类位置尚不明确的含义，查找记录时应保持完整名称。

Overview
'Puntius' snyderi is a small cyprinid closely resembling a related barb. Natural coloration is greenish with dark flank marks. Extremely small, inconspicuous barbels, sometimes absent, are the most useful external clue; a golden-barb style sales name cannot reliably separate these fishes.
Distribution & habitat
It occurs in central and northern Taiwan and has mainland Chinese records, some of which have retained a related species' name in older accounts.
Shallow margins of slow streams, irrigation channels, and ponds are favored, particularly where aquatic or bankside vegetation is dense.
Aquarium setup
Provide a base of at least around 90 × 30 cm. Dense planting and a dark substrate help show its coloration. Floating plants, wood, and roots soften light and add structure.
Strong filtration currents are unnecessary, though some movement is appreciated. A stream-style arrangement can work without turning the aquarium into a torrent.
Diet & feeding
It naturally forages on diatoms, algae, organic detritus, small insects, worms, crustaceans, and other plankton. Captive feeding is straightforward. Combine live or frozen bloodworms, Daphnia, and brine shrimp with quality flakes or granules, including some plant- or algae-rich preparations.
Behaviour & compatibility
It appears peaceful with similar-sized, mild companions sharing its conditions. A mixed-sex group of eight to ten or more is preferable. Other suitable schooling fishes can provide reassurance, while males show stronger color during competition for females and position.
Sexual dimorphism
Adult females have fuller bellies and generally grow slightly larger. Mature males develop red along the lower body.
Notes
Compared with wild-type 'Puntius' semifasciolatus, this fish has minute or absent barbels, a deeper body, and roughly four or five principal dark flank marks. The relative has more obvious barbels, a slimmer shape, and about seven to nine main markings.
They should not simply be treated as color variants of one fish. Quotation marks around the genus preserve the historically uncertain placement of this group and belong with the complete name when checking records.
