概述
非洲驼背鱼（Papyrocranus afer）体形大，成熟后领地性和攻击性越来越明显，适合有大型鱼经验的饲养者。幼鱼能暂时成群，不意味着成年后仍能同样相处，单独维持通常更稳妥。
分布与栖息地
分布横跨非洲西部和中部多个国家，涉及尼日尔河、克罗斯河、萨纳加河、塔诺河及普拉河等水系。通常在植被茂密的缓流河段或静缓回湾中生活。
饲养环境
成年鱼底面积至少约 210 × 90 cm。幼鱼可暂用较小缸养大，但必须预先准备最终空间。照明宜暗，布置密植区、沉木及扭曲树根形成掩护，水流保持很弱。
食性与喂食
主要为肉食性，可接受多数肉质活饵和冷冻饵，部分也吃颗粒。可搭配小鱼、虾肉、切碎贝肉、蚯蚓和肉食鱼颗粒，避免菜单长期单一。
习性与混养
攻击性是主要限制。成熟后尤其可能针对其他刀鱼，也可能攻击其他看不顺眼的大鱼。即使存在与大型伙伴相安无事的个例，也有对同类伙伴发动攻击的观察，不能将成功个案当成普遍保证。
以单条单缸为较稳妥的安排。若尝试混养，只能考虑非常强健、体形合适的伙伴及足够空间，并随时观察互动；幼时群养关系不具备成年保证。
繁殖
缸内繁殖尚无确认记录，不能按其他刀鱼的护卵经验推断本种流程。
补充说明
臀鳍与尾鳍相连，构成长而连续波动的鳍，能帮助它以独特方式移动。成年花纹可相当醒目，但观赏性并不能降低体形与攻击性带来的饲养难度。

Overview
The large Papyrocranus afer becomes increasingly territorial and aggressive as it matures. It is best suited to experienced keepers with substantial accommodation. Juvenile tolerance in a group does not predict adult compatibility, and solitary housing is generally the more dependable choice.
Distribution & habitat
It ranges widely across western and central Africa, including the Niger, Cross, Sanaga, Tano, and Prah river systems. Dense vegetation in slow river sections and sluggish backwaters is typical habitat.
Aquarium setup
An adult needs a footprint around 210 × 90 cm. Smaller quarters may serve while a juvenile grows, but final accommodation should be planned in advance. Subdued lighting, densely planted areas, wood, and tangled roots provide cover. Keep current minimal.
Diet & feeding
It is primarily carnivorous and accepts a wide range of meaty live and frozen foods. Some individuals also take pellets. Vary offerings such as appropriately sized fish, prawn, chopped mussel, earthworms, and carnivore pellets rather than relying on one item.
Behaviour & compatibility
Aggression is the principal limitation. Maturing fish may target other knifefishes and can also attack unrelated large companions. Reports of peaceful coexistence are balanced by accounts of attacks on the same kinds of tankmates, so individual success is not a general guarantee.
Keeping one in its own aquarium is the more reliable arrangement. Any shared setup requires exceptionally robust, appropriately sized companions, substantial space, and close observation. A juvenile group's apparent harmony should not be treated as an adult arrangement.
Breeding
Confirmed aquarium reproduction is unreported. Parental-care behavior of other knifefishes does not establish a reproductive procedure for this species.
Notes
Its joined anal and caudal fins form a long undulating edge that contributes to its distinctive movement. Adult patterning can be striking, but appearance does not reduce the practical demands imposed by size and aggression.
