概述
Polypterus palmas palmas在恐龙鱼中较活跃、相对温和，体形也较小，但仍是会吞小鱼的捕食者。
分布与栖息地
已记录分布包括加纳、刚果民主共和国、喀麦隆、利比里亚、几内亚、科特迪瓦、塞拉利昂。这一条目的已知分布横跨多个西非及中非国家。
饲养环境
成鱼参考缸体为 120 × 45 × 38 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。商品标签可能混入近缘类型（Polypterus palmas polli），不要单凭 palmas 这一标签认定身份。

Overview
Polypterus palmas palmas: Comparatively active and tolerant among bichirs, it is smaller than many relatives but still preys on small fishes.
Distribution & habitat
Recorded countries include Ghana, Democratic Republic of Congo, Cameroon, Liberia, Guinea, Ivory Coast, Sierra Leone. Records span several countries in western and central Africa.
Aquarium setup
Allow an adult approximately 120 × 45 × 38 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.Trade labels using palmas may refer to Polypterus palmas polli, so the shortened name alone does not confirm identity.
