概述
Polypterus bichir bichir下颌向前突出，是大型下颌型恐龙鱼。
分布与栖息地
已记录分布包括埃及、肯尼亚、尼日利亚、喀麦隆、埃塞俄比亚、科特迪瓦、乍得、加纳、几内亚比绍。通常栖于湖泊浅水区，也见于河流和沼泽。
饲养环境
成鱼参考缸体为 180 × 60 × 60 cm，底面积比单纯增加水深更重要。采用柔软底砂，沉木和光滑石块围出躲藏处，水草可选用。缸盖要严密防逃，同时必须让鱼能够上浮呼吸空气，不能封死水面通道。
食性与喂食
属于肉食鱼，可提供虾、蚯蚓、贝类和鱼类等活饵或冷冻饵。多数不容易接受干粮，但有个体能吃颗粒。它偏夜行，视力较弱，主要靠嗅觉找食物，投喂时要确认食物确实送到鱼能发现的位置。
习性与混养
不能与能被吞下的鱼共养；对足够大的伙伴则相对温和。混养可从体形合适的其他恐龙鱼、倒游鲶、虎鱼、刀鱼、大型攀鲈或脂鲤中选择，仍须避免口径上的捕食风险。
雌雄区分
雄鱼臀鳍比雌鱼更厚实。
繁殖
尚无本条目的人工繁殖记录，雨季产卵及其他恐龙鱼的经验提供了一些尝试方向。偏软、微酸的水和植物或产卵拖把可作为参考，但近缘鱼的散卵流程与孵化时间不能视为本种已验证结果。
补充说明
幼鱼有外鳃，成长后会消失。新到的野生鱼可能带有病原或寄生虫，应留意初期状态。

Overview
Polypterus bichir bichir: It is a large lower-jawed bichir with a projecting lower jaw.
Distribution & habitat
Recorded countries include Egypt, Kenya, Nigeria, Cameroon, Ethiopia, Ivory Coast, Chad, Ghana and GuineaBissau. Shallow lake habitats are typical, with additional records in rivers and marshes.
Aquarium setup
Allow an adult approximately 180 × 60 × 60 cm. Floor area matters more than depth alone. Use a soft base, wood, and smooth stones to provide retreats, with plants optional. A close-fitting cover prevents escape while access to air at the water surface must remain unobstructed.
Diet & feeding
A natural carnivore, it takes meaty live or frozen items such as shrimp, earthworms, mussels, and fish. Dry foods are often rejected, although some individuals accept pellets.It is nocturnal, with weak vision and a strong reliance on smell. Check that food reaches a place where the fish can locate it.
Behaviour & compatibility
Companions that fit in its mouth are unsafe, even though larger fishes are generally treated peacefully. Possible companions include suitably sized bichirs, upside-down catfish, tigerfish, knifefish, larger climbing perches, and characins.Assess eventual size rather than juvenile compatibility.
Sexual dimorphism
The male anal fin is thicker than the female’s.
Breeding
Captive breeding is unrecorded for this form. Rainy-season spawning and experience with other bichirs suggest possible approaches involving soft, mildly acidic water and plants or mops. The relatives’ egg-scattering sequence and development times should not be treated as a demonstrated outcome here.
Notes
Young bichirs possess external gills that disappear with growth. Newly acquired wild fish may carry infections or parasites, so watch their condition carefully during acclimation.
