概述
Rhinodoras dorbygnyi 是偏夜行、初到环境常躲藏的棘鲶科鱼。对体形合适的伙伴通常温和，但会吞吃小鱼，不能把安静的白天表现理解为适合所有小鱼混养。
分布与栖息地
分布于玻利维亚、巴拉圭、乌拉圭、阿根廷、巴西的巴拉那河流域。在缓流或静水的支流、小溪和沼泽中，常藏在树根及淹水植被间。
饲养环境
成鱼参考缸体至少为 120 × 60 × 60 cm。保持柔和灯光，用陶罐、合适粗细的管道或交错沉木提供多个躲藏处。水草并非必需，但能遮光并增加安全感。
刚入缸时可能整天藏着，随适应及成长往往更大胆，成鱼也可能在开灯时巡游，不必为观察而频繁翻动掩体。
食性与喂食
杂食且通常容易开口。用优质沉底颗粒或片状底栖饲料作基础，搭配红虫、小蚯蚓等活饵与冷冻饵。新鱼有时只在熄灯后吃，应配合其作息投喂；安定后常会在喂食时主动出来。
习性与混养
伙伴必须大到不会被视为食物，同时避免强领地型鱼。可选择体形合适的温和脂鲤、鲤科鱼、丝足类、卵胎生鱼、慈鲷及其他不强占地盘的鲶鱼。
通常能容忍同种，多尾可能白天共用一处躲藏空间。偶有挤占位置，但一般不会造成身体伤害。
繁殖
尚无爱好者人工繁殖记录。

Overview
A nocturnal, initially retiring doradid, Rhinodoras dorbygnyi is generally tolerant of suitably sized companions. Small fishes remain potential prey, however, so daytime inactivity should not be mistaken for compatibility with every community fish.
Distribution & habitat
Its range includes the Paraná basin of Bolivia, Paraguay, Uruguay, Argentina, and Brazil. Slow tributaries, creeks, and swamps provide roots and flooded vegetation for daytime shelter.
Aquarium setup
Allow an adult at least 120 × 60 × 60 cm of aquarium space. Use subdued lighting and multiple refuges made from pots, appropriately sized tubing, or tangled wood. Plants are optional but provide additional shade and cover.
New arrivals may remain hidden all day. Confidence commonly increases with growth and acclimation, and adults may eventually cruise even under aquarium lighting. Frequent disturbance of their retreats is unnecessary.
Diet & feeding
An adaptable omnivore, it accepts quality sinking pellets or bottom-feeding tablets as a staple, supplemented with bloodworms, small earthworms, and other live or frozen foods. Feed after lights out if a new fish remains reluctant to emerge. Settled specimens often learn to forage at normal feeding times.
Behaviour & compatibility
Choose peaceful companions too large to be swallowed and avoid territorial pressure. Appropriately sized characins, cyprinids, gouramis, livebearers, cichlids, and nonterritorial catfishes are possible choices.
Conspecifics are usually tolerated. Several individuals may occupy the same daytime retreat, with occasional jostling that seldom causes injury.
Breeding
Reproduction has not been documented in hobby aquaria.
