概述
Cichla monoculus 是大型食鱼慈鲷，成年体长可达 80 cm，更适合具备大型设施的资深饲养者或公共水族馆。幼鱼外观小巧不代表可以长期用普通缸容纳，购买前应落实成年后的空间。
分布与栖息地
分布于哥伦比亚、法属圭亚那、秘鲁和巴西，记录包括索利蒙伊斯河、奥亚波克河及阿拉瓜里河。可在亚马孙地区多种水域环境中出现。
饲养环境
成年鱼需要约长 305 cm、高 91 cm、宽 122 cm 或更大的设施。布景宜疏朗，保留大量游泳空间，使用大型沉木及强健植物。个体大、排泄负担重，需要处理能力相称的外置过滤或底滤。
食性与喂食
自然以鱼为食。人工可提供虾肉、贻贝肉及适口鱼肉等动物性食物，按其口径和体型安排食物尺寸。
习性与混养
有领地意识，攻击性中等，任何能被视为食物的小伙伴都有被吞食的风险。与其他大型鱼或同种群体共处需要极大的空间，不能仅凭幼鱼阶段相安无事判断成鱼兼容性。
雌雄区分
雄鱼较大，成熟后头顶逐渐形成额隆。
繁殖
人工繁殖报告不多，曾有一窝约 700–800 尾鱼苗的记录。野外一年可多次繁殖，但现有信息不足以给出完整的家庭繁殖流程。
补充说明
它耐受能力较强，也能适应一定环境变化，但这些特点不能降低对成年设施和持续过滤能力的要求。
English
Overview
Cichla monoculus is a large fish-eating cichlid reaching the recorded adult size of 80 cm. It belongs in very substantial facilities, often those of public aquariums. A small juvenile should be acquired only when adult accommodation is already realistic.
Distribution & habitat
Records span Colombia, French Guiana, Peru, and Brazil, including the Solimões, Oyapock, and Araguari rivers. It occupies a variety of Amazon-region habitats.
Aquarium setup
Adult housing needs approximately 305 cm of length, 91 cm of height, and 122 cm of width or more. Keep decoration sparse enough to preserve extensive swimming space. Large wood and robust plants are appropriate, with external or sump filtration capable of handling substantial waste production.
Diet & feeding
Natural feeding is piscivorous. Suitable captive foods include shrimp flesh, mussels, and appropriately sized fish pieces. Match food size to the individual rather than relying on its small size at purchase.
Behaviour & compatibility
Territorial and moderately aggressive, it consumes tankmates small enough to be regarded as prey. Conspecific groups or combinations with other large fishes need exceptionally extensive space. Peaceful coexistence while young does not establish lasting adult compatibility.
Sexual dimorphism
Males grow larger and develop a forehead hump as they mature.
Breeding
Captive reports are limited, with broods of roughly 700–800 fry recorded. Wild fish may reproduce more than once annually. Available information does not establish a complete repeatable home-breeding procedure.
Notes
Hardiness and some adaptability do not remove the need for adult-scale accommodation and powerful, sustained filtration.
