概述
点斑蜥形脂鲤（Iguanodectes spilurus）身体修长，背鳍与臀鳍半透明，尾鳍有明显深色斑。它没有近缘红线种的红色体侧纵纹，是本属分布较广的成员，需要稳定洁净的群养环境。
分布与栖息地
广布于亚马孙河、奥里诺科河、埃塞奎博河和托坎廷斯河水系，涉及巴西、秘鲁、玻利维亚、厄瓜多尔、哥伦比亚、委内瑞拉和圭亚那。模式产地在巴西塔帕若斯河水系的库帕里河。
推测偏好小支流、小河、牛轭湖和淹水森林，而非主河道。在奥里诺科河常见于清水、沙底且植被密集的棕榈沼泽溪流，其他地方也有流水黑水及静止洪泛湖的采集记录，因此不能只按一种水流环境概括。
饲养环境
底面积至少约 120 × 45 cm。沙底搭配沉木根枝较适合，也可使用植物缸。它对水质恶化敏感，必须在生物过滤成熟、环境稳定后再放入。
食性与喂食
天然可能杂食，以小型无脊椎动物、甲壳动物、丝藻和落果等为食。缸内即使接受干粮，也宜提供多样食物，包括红虫、蚊幼体和水蚤等活饵或冷冻饵。
习性与混养
总体温和，可与体型匹配、需求相符的脂鲤、胸斧鱼、铅笔鱼、底层鲶鱼和不捕食小鱼的慈鲷混养。
雌雄混合至少 8～10 条，并可搭配其他温和群游鱼增强安全感。雄鱼为雌鱼和群体地位竞争时会展示鲜艳体色，雌鱼多于雄鱼可减少个别鱼过度受扰。
雌雄区分
繁殖雄鱼臀鳍前部鳍条会出现小钩和瓣状结构。
补充说明
半透明背鳍和臀鳍、缺少红色体侧线以及明显尾鳍深斑，是区别本属近似种的组合线索。它有多个英文商品名，不能把不同标签自动当作不同物种。

Overview
A slender profile, translucent dorsal and anal fins, and a conspicuous dark tail mark characterize Iguanodectes spilurus. It lacks the red flank line of some relatives and is one of the genus's most widespread members. Stable, clean group housing is important.
Distribution & habitat
Its Amazon, Orinoco, Essequibo, and Tocantins range covers Brazil, Peru, Bolivia, Ecuador, Colombia, Venezuela, and Guyana. The type locality is the Cupari in Brazil's Tapajós drainage.
Smaller tributaries, rivers, oxbows, and flooded forests are presumed preferred to main channels. Orinoco records often involve clear sandy morichal habitats with dense vegetation. Elsewhere it has been collected in flowing blackwater and still floodplain lakes, so one current regime cannot represent its entire range.
Aquarium setup
Allow at least about 120 × 45 cm of floor space. Sand with roots and branches is likely appropriate, and planted layouts are another option. Poor water quality is a concern; introduce it only after biological filtration and conditions have stabilized.
Diet & feeding
The natural diet is thought to include small invertebrates, crustaceans, filamentous algae, and fallen fruit. Offer a varied captive menu, combining accepted preparations with live or frozen bloodworms, mosquito larvae, and water fleas.
Behaviour & compatibility
It is generally peaceful. Suitably sized characins, hatchetfishes, pencilfishes, bottom catfishes, and nonpredatory cichlids are possible companions where requirements match.
A mixed-sex group of at least eight to ten is preferable, with other peaceful schooling fishes providing reassurance. Males display stronger colors while competing for mates or social rank. A female-biased ratio helps distribute attention.
Sexual dimorphism
Breeding males develop small hooks and fleshy projections on the front anal-fin rays.
Notes
Use the combined translucent fins, absence of a red flank stripe, and dark tail mark when separating it from similar relatives. Several English trade names exist, without necessarily indicating different species.
