概述
天竺细丝鲶（Phalacronotus apogon）是开阔水域的大型食鱼鲶，幼鱼有时以亮蓝、金属色等商品名出售，成年却只适合公共展示设施或极大型私人缸。购鱼前应把长期活动空间放在外观吸引力之前。
分布与栖息地
广布东南亚大陆及苏门答腊、婆罗洲、爪哇等大巽他群岛，栖息主河道和大溪流的开阔水中，水体常因悬浮泥沙而浑浊。雨季会进入临时洪泛区域；大陆和岛屿群体是否完全同种仍待确认。
饲养环境
只适合非常大型的设施，不宜用普通家庭缸作长期方案。造景形式并非核心，弱光较合适；水化学变化可能带来问题，应等生物系统成熟、水质稳定后再入鱼。
食性与喂食
天然专吃鱼，主要追捕中上层开阔水中的鱼类。新到个体常只认活鱼，但多数可在认出非活饵后逐渐转换。不要长期依赖活饵鱼，也避免牛心、禽肉等陆生动物肉。
习性与混养
单养或与体形相近、温和且无法被吞下的鱼搭配较合适。足够大的缸似乎可同种群养，但不能由此降低每尾所需空间。
雌雄区分
成年雄鱼较纤细，胸鳍硬刺后缘有锯齿；雌鱼更丰满，相应边缘平滑。
繁殖
野外产卵与雨季开始及季节性洪水同步，不能把这一季节规律当作已经验证的缸内繁殖方法。

Overview
A large open-water fish predator, Phalacronotus apogon sometimes reaches shops under metallic or blue-themed juvenile labels. Adult needs restrict it to public installations or exceptionally large private aquariums. Appearance does not reflect the scale of lifetime housing.
Distribution & habitat
It is widespread across mainland Southeast Asia and the Greater Sunda Islands. Main channels and large streams provide open water, often turbid with sediment. Seasonal flooding opens additional habitat. Mainland and island populations may not all represent the same species.
Aquarium setup
Ordinary home aquariums are unsuitable for long-term care. Exact decor is secondary to adequate scale, subdued light, and stable water. Introduce it only after biological maturity because changing chemistry can cause problems.
Diet & feeding
It is an obligate fish eater, hunting open-water prey in the middle and upper levels. New imports often accept only live fish, but most can learn to recognize nonliving alternatives. Avoid a long-term feeder-fish routine and mammalian or avian meats.
Behaviour & compatibility
Solitary housing or similarly sized peaceful companions are the main options. Fish must be too large to swallow. Groups apparently can work in suitably vast aquariums, without reducing the overall space requirement.
Sexual dimorphism
Adult males are slimmer and have serration along the rear pectoral-spine edge, while females are fuller and lack it.
Breeding
Natural spawning coincides with the start of seasonal rains and flooding; an aquarium breeding procedure is not established.
