概述
Synaptolaemus latofasciatus 的全身有橙至黄色与深褐至黑色相间的宽横带，花纹延伸到体侧下部。不同地点的吻形和配色有所变化，不能仅按一条鱼的花纹就判断所有种群完全一致。
分布与栖息地
已知分布包括委内瑞拉、巴西的奥里诺科河上游、Casiquiare 水道和亚马孙中下游区域，记录涉及 Negro、Madeira、Trombetas、Xingu 及 Tapajós 等水系。保留具体河流来源，有助于比较外观差异。
饲养环境
建议底面积至少约 120 × 45 cm。规划环境时应给成体留下相应空间，不宜只凭体色醒目就把它作为小缸配鱼。
食性与喂食
野外可能在水下硬质表面巡游啄食藻、无脊椎动物和有机碎屑。缸内据观察通常愿意接受多种食物，但应避免高蛋白菜单，不把偏动物性饵料当作唯一投喂方向。
补充说明
它最初被放在 Leporinus 属，后来检查模式标本，确认与曾称 Synaptolaemus cingulatus 的鱼相同，才采用现有组合名。旧名称有助于对照贸易和文献记录。
较长而近乎直立的闭口下颌、特有的门齿比例及贯穿全身的横带，是区分近似同科鱼的线索。鳍形、嘴形与来源应一起核对，不宜只依赖笼统商品名。

Overview
Synaptolaemus latofasciatus has broad alternating orange or yellow and dark brown or black bands extending across the body and below the lateral line. Snout shape and coloration vary geographically, so one specimen does not represent every population's appearance.
Distribution & habitat
Records span the upper Orinoco, Casiquiare waterway, and middle to lower Amazon region in Venezuela and Brazil. Recorded systems include the Negro, Madeira, Trombetas, Xingu, and Tapajós. Preserve river-of-origin information when comparing forms.
Aquarium setup
Provide at least about 120 × 45 cm of floor space. Plan around the adult fish rather than choosing a small aquarium simply because its striking pattern makes it attractive as an addition.
Diet & feeding
It probably browses algae, invertebrates, and detritus from submerged hard surfaces. Aquarium observations suggest broad food acceptance, but protein-rich menus should be avoided. Do not rely exclusively on rich animal foods.
Notes
Originally placed in Leporinus, it was later recognized through examination of the type specimen as the fish previously called Synaptolaemus cingulatus. The older names remain useful when comparing trade and literature records.
An elongated lower jaw appearing nearly vertical when closed, distinctive tooth proportions, and complete transverse bands aid recognition. Consider mouth structure and provenance together instead of relying on a broad trade label.
