概述
怖矛齿鲶（Belodontichthys dinema）是开阔水域的大型食鱼鲶，成年所需空间远大于幼鱼暂养缸。它会跳跃，能吞下的小鱼都属于猎物，选购前需要确认长期设施和持续供饵能力。
分布与栖息地
已知分布于马来西亚、印度尼西亚的马来半岛、苏门答腊和婆罗洲，包含卡普阿斯河及上游季节性洪泛湖。生活在大河和相连湖泊，在开阔水中捕食小鱼；中南半岛旧记录多属另一个近似种。
饲养环境
180 × 60 × 60 厘米只是起点，成年需要大得多的空间。保留充分游动区，宽口径管道等可作大型藏处，水草很难承受这种体形的活动。强效过滤与规律大量换水应对残饵和排泄，缸盖要足够重且贴合，防止撞开跳出。
食性与喂食
属于专性食鱼者，缸养经验中常只接受活鱼。若饲养，应有稳定、健康且提前隔离观察的饵料鱼来源，不能默认它一定能顺利转吃颗粒或鱼肉。
习性与混养
通常单尾更合适；若考虑伙伴，只能选择强健且大到无法被吞下的鱼。
补充说明
头体侧扁、吻部上翘、胸鳍较长，可辅助辨认。以本种名从泰国或中南半岛出口的鱼，很可能是 Belodontichthys truncatus，两者分布和形态应分开核对。

Overview
An open-water fish predator, Belodontichthys dinema requires far more room as an adult than a juvenile setup suggests. Strong jumping ability and predation on any swallowable companion make both secure housing and a dependable food supply essential before purchase.
Distribution & habitat
The known range covers the Malay Peninsula, Sumatra, and Borneo in Malaysia and Indonesia. Large rivers and connected lakes, including the upper Kapuas flood-lake system, provide open-water hunting habitat. Older Indochinese records largely concern a different species.
Aquarium setup
Treat 180 by 60 by 60 cm only as a starting minimum; an adult needs considerably more space. Wide pipes can provide a few shelters without compromising open swimming room. Plants are unlikely to withstand its movements. Powerful filtration and large regular changes handle heavy waste, and a heavy close-fitting lid must resist jumping.
Diet & feeding
It is an obligate fish eater, and aquarium reports describe acceptance of live fish only. Care therefore depends on a reliable supply of healthy prey quarantined before use; conversion to pellets or fish pieces should not be assumed.
Behaviour & compatibility
Solitary care is the standard option. Any potential companion must be robust and too large to swallow.
Notes
A compressed head and body, upturned snout, and long pectorals contribute to identification. Fish exported under this name from Thailand or elsewhere in Indochina are likely Belodontichthys truncatus, so origin and form deserve separate checks.
