概述
Polypterus teugelsi身体相对修长，上半身有黑色网纹，腹部橙色、胸鳍漆黑。其外观很有辨识度，人工繁殖资料却很有限。
分布与栖息地
已记录分布包括喀麦隆。可能是喀麦隆克罗斯河流域的特有种。常见于遮阴、缓流的雨林溪流，岸边垂悬植被丰富。
饲养环境
成鱼参考缸体为 150 × 60 × 60 cm，底面积比单纯增加水深更重要。布置可参考其他恐龙鱼的经验：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
天然为肉食，喂养方式可参考同属种类，优先尝试虾、蚯蚓、贝和鱼等活饵或冷冻饵，干粮接受度可能较低。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
能被吞下的鱼不安全。它可能像其他恐龙鱼一样对体形足够大的伙伴相对温和，但这仍是类比判断。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。
繁殖
尚无人工繁殖记录，自然繁殖行为也了解很少。
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 teugelsi: A slender body with black upper-body reticulation, an orange abdomen, and black pectoral fins gives it a distinctive appearance. Reproductive knowledge remains limited.
Distribution & habitat
Recorded countries include Cameroon It is probably restricted to Cameroon’s Cross River drainage, inhabiting shaded, slow rainforest streams beneath lush overhanging vegetation.
Aquarium setup
Allow an adult approximately 150 × 60 × 60 cm. Floor area matters more than depth alone. Care is inferred from other bichirs: 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
It is naturally carnivorous. Feeding guidance follows other bichirs, favoring live or frozen shrimp, worms, mussels, and fish; dry preparations may be poorly accepted.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
Any companion that fits in the mouth is unsafe. Relative tolerance of larger fishes is considered likely by comparison with other bichirs, rather than firmly established. Possible companions include suitably sized bichirs, upside-down catfish, tigerfish, knifefish, larger climbing perches, and characins.Assess eventual size rather than juvenile compatibility.
Breeding
Captive reproduction is unrecorded, and little is known about breeding behavior.
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.
