概述
利氏叉尾鲶（Wallago leerii）是只适合极大型公共展示设施的捕食鲶，幼鱼虽可能进入贸易，成体并不是普通家养对象。它有巨大的口和向后弯的牙，不能把暂时没有吞掉的伙伴当作长期安全搭配。
分布与栖息地
记录来自越南、老挝、柬埔寨、泰国、马来西亚、印度尼西亚北部和新加坡，包括湄公河等水系。主要生活在河流中，随季节长距离移动，雨季进入淹水森林，部分群体繁殖时转入小支流。
饲养环境
设施需以极大型成鱼空间为前提。造景容易被移动或破坏，简洁或裸底布局较现实，巨量有机废物需高效大型过滤处理。它曾在野外跨过短距离陆地寻找新水域，边界和重型密合缸盖都要可靠。
食性与喂食
野外胃内容物含小鱼和淡水虾，饲养也应以适口动物性食物为主。新到个体有时只认活鱼，多数可逐渐训练接受非活饵。幼鱼可每天喂，生长减慢后每周一餐通常足够；避免牛心、禽肉等陆生动物肉。
习性与混养
不宜与其他鱼搭配，较大的伙伴可能只是暂时未被捕食，随着它长大风险会增加。
雌雄区分
可通过生殖突比较性别，雄鱼的生殖突明显更细。
补充说明
同类商品名和幼鱼体形不能代替物种核对，购买前必须按成年巨型鱼的需求判断设施是否真正适合。

Overview
A huge predatory catfish, Wallago leerii belongs only in the largest public-scale facilities. Juvenile trade availability does not make it a normal home-aquarium subject. An enormous mouth and backward-pointing teeth leave companions at risk even if they initially avoid being swallowed.
Distribution & habitat
Records include Vietnam, Laos, Cambodia, Thailand, Malaysia, northern Indonesia, and Singapore, with the Mekong among its river systems. It moves substantial seasonal distances, using flooded forest during the rains and, in some populations, smaller tributaries for spawning.
Aquarium setup
Housing must be planned at a truly enormous scale. A sparse or bare arrangement is more practical than vulnerable decor, and heavy organic waste requires massive filtration. Reported short overland movements make secure boundaries and a heavy close-fitting cover especially important.
Diet & feeding
Wild stomach contents include small fish and freshwater prawns. A meaty aquarium diet is appropriate. Some newcomers initially accept only live fish, but most can learn nonliving alternatives. Juveniles may feed daily, tapering toward weekly meals as growth slows. Avoid mammalian and avian meats.
Behaviour & compatibility
Other fish are unsuitable companions. A larger neighbor may merely avoid predation temporarily as the catfish continues growing.
Sexual dimorphism
The genital papilla is noticeably narrower in males and can help distinguish the sexes.
Notes
Broad trade labels and a small juvenile body should not replace identification and assessment of adult facilities.
