概述
大刺鳅（Mastacembelus armatus）成年体型很大，白天常躲藏，有时将身体埋入沙中。它会吃小鱼，需要适合成年体型的长期空间、充分藏身处以及严密缸盖，不能只按幼鱼大小选缸。
分布与栖息地
分布记录包括印度、泰国及印度尼西亚苏门答腊。多利用水流较缓、接近静水的环境。
饲养环境
可按至少约 120 × 60 × 60 cm、432 L 准备基础空间，并充分考虑大型成体及混养所占区域。密植水草，加入浮水遮蔽，沉木、石洞或塑料管可供白天躲藏。
铺柔软沙底供掩埋，弱光有助它更常离开藏身处。水流宜柔和，缸盖及设备缝隙必须封好，它能从很小开口逃出。轻微半咸水也曾被作为饲养选择，但不能仅凭这一建议把已有淡水环境突然加盐。
食性与喂食
偏好虾、磷虾及小型海鱼等动物性食物，活饵或冷冻饵均可利用，大个体需要与体型相应的足量食物。少数也接受植物材料，但并不常见。
习性与混养
对体型相配的同伴通常较平和，但野外会捕食鱼，混养对象必须大到无法成为猎物。不要把总体平和当作小鱼安全的保证。
雌雄区分
成熟待产雌鱼腹部更丰满，其他稳定外部特征并不明确。
繁殖
尚无明确的爱好者人工繁殖记录。
补充说明
本种是水族贸易中较常见的亚洲刺鳅之一，“刺鳅”之名来自背部排列的硬棘。鳗形外观不代表可以忽略底砂、隐蔽和逃逸问题，观察是否正常进食也比白天是否常出现更重要。
English
Overview
The large adult size of Mastacembelus armatus requires permanent housing plans beyond a juvenile aquarium. It hides during daylight, sometimes burying itself, and consumes small fishes. Sand, extensive shelter, and secure containment are central to care.
Distribution & habitat
Records include India, Thailand, and Sumatra in Indonesia. Slow or nearly still waters are associated with its maintenance requirements.
Aquarium setup
An aquarium around 120 × 60 × 60 cm and 432 L provides a stated baseline, with due allowance for large adults and any companions. Dense planting and floating shade can surround wood, rock caves, or plastic tubes used as daytime retreats.
Use soft sand for burial. Dim illumination encourages more visible activity, and circulation should remain gentle. Seal even small openings around the cover and equipment. Mildly brackish maintenance has also been suggested, but that is not a reason to abruptly add salt to an established freshwater system.
Diet & feeding
Animal foods such as shrimp, krill, and small marine fish are favored. Live or frozen offerings must provide sufficient food for a large individual rather than relying on small portions. A few specimens also accept plant material, but this is unusual.
Behaviour & compatibility
It is generally tolerant of suitably sized companions, while its natural fish predation excludes small species. A broadly peaceful disposition does not make small tankmates safe.
Sexual dimorphism
Ripe females become fuller through the abdomen; other dependable external distinctions are not established.
Breeding
Clear hobby breeding records are unavailable.
Notes
It is among the more frequently traded Asian spiny eels. The common family name refers to hardened rays along the back. An eel-like shape does not remove the need for sand, concealment, and escape prevention; regular feeding is a more useful observation than constant daytime visibility.
