概述
双斑绚鲶(Ompok bimaculatus)是体形较大的鲶鱼,通常温和而胆小,但满口利齿足以捕食小伙伴。它的广泛分布可能包含多个尚未厘清的近似种,不能把各地记录的耐受性简单看成每一尾都相同。
分布与栖息地
记录从阿富汗、巴基斯坦和南亚多国延至中国及东南亚。环境包括缓慢浑浊溪流、渠道和有水流的河道,雨季会迁入洪泛区。不同地区个体形态差异明显,现有广域分布需结合物种身份理解。
饲养环境
可参考 180 × 60 × 60 厘米,提供大量游动空间和合口径宽管等躲藏处。水草未必能承受其活动。强效过滤配一定水流,严格规律换水,应对较多残饵排泄并避免水质恶化。
食性与喂食
通常接受大多数活饵、冷冻饵及干粮,较大个体可用蚯蚓、虾块、贝肉和颗粒饲料。
习性与混养
伙伴必须大到不能吞下,性情温和的中大型鱼较合适。不能因为它胆小就与小鱼混养。
雌雄区分
雄鱼胸鳍硬刺边缘有锯齿,雌鱼没有;成熟雌鱼身体更厚实。
繁殖
人工繁殖记录依赖激素催产,不能当作普通缸内自然配对产卵的成熟方法。
补充说明
偶见黄色或白化个体,但不同地理群体的种界尚不清楚,颜色变化不应替代物种核对。

English
Overview
Large but often shy, Ompok bimaculatus is peaceful only in the sense of social aggression: smaller fish are still vulnerable to its sharp teeth. Its very broad reported range may encompass more than one species, so apparent environmental tolerance may conceal population differences.
Distribution & habitat
Reported distribution extends from Afghanistan and Pakistan across South Asia to China and Southeast Asia. Habitats include slow turbid streams, canals, and flowing rivers, with wet-season movements into flooded areas. Marked differences among populations complicate interpretation of that broad range.
Aquarium setup
Use the suggested 180 by 60 by 60 cm reference with extensive open space and suitably broad shelters. Plants may be disturbed by its movements. Strong filtration, some current, and regular water changes handle substantial waste and prevent declining conditions.
Diet & feeding
Most live, frozen, and prepared foods are accepted. Larger specimens can take earthworms, suitable prawns and mussels, and pellets.
Behaviour & compatibility
Select peaceful medium or large companions beyond swallowing size. Its shy behavior does not make small fish safe.
Sexual dimorphism
Males have pectoral-spine serration absent in females, while mature females are thicker-bodied.
Breeding
Reported captive propagation relies on hormonal induction rather than an established routine for spontaneous aquarium spawning.
Notes
Yellow and albino forms occasionally appear, but unresolved geographic variation makes color a poor substitute for species identification.
