概述
罗宾氏兵鲶（Brochis robineae）是温和群居的甲鲶，花纹醒目。人工繁殖可以实现，但诱发产卵并非最容易，需耐心调理群体与环境。
分布与栖息地
原生巴西内格罗河上游，见于主河道及其支流。
饲养环境
可参考约 60 × 38 × 30 厘米，铺细沙，配平滑岩石、沉木、密植和浮水遮蔽。维持适度水流、水面扰动与充氧，避免底滤板并保持底床洁净，污底可能损伤触须。
食性与喂食
接受多种下沉干粮，也可搭配红虫、丰年虾与切碎蚯蚓等活冷冻食物，保持多样。
习性与混养
至少六尾共同饲养通常更活跃且自信。可配合适温和小鱼及温和鲶鱼，避开很大或好斗的伙伴。
雌雄区分
从上方观察抱卵雌鱼，身体会更圆宽。
繁殖
可一雌两雄，海绵过滤配细叶植物，水温约 24 °C、酸碱度约 7。用多样饵料调理，雌鱼抱卵后试偏凉水换 50%～70% 并加强充氧与水流。产卵时可见典型丁字姿势，雌鱼分批把卵黏在玻璃等表面。成鱼可能吃卵，应分开亲鱼或移卵，用原缸水充氧孵化并及时除霉卵。通常三至四天孵化，卵黄吸收后可喂微虫及丰年虾无节幼体，薄沙底似有利于育苗。

Overview
A strikingly patterned, peaceful cory catfish, Brochis robineae can reproduce in aquaria but is not among the easiest to stimulate into spawning. Group condition and patient environmental management matter.
Distribution & habitat
It occurs in the upper Negro in Brazil, both in the main river and its tributaries.
Aquarium setup
A suggested tank is about 60 by 38 by 30 cm. Use fine sand with smooth stones, wood, planting, and floating cover. Flow and surface movement support oxygenation. Keep the substrate clean and avoid undergravel filtration to protect the barbels.
Diet & feeding
Sinking prepared foods can be combined with small live or frozen items such as brine shrimp and chopped earthworms. Vary the diet to maintain condition.
Behaviour & compatibility
Keep at least six to encourage confidence and activity. Choose peaceful companions of suitable size rather than large or aggressive fishes.
Sexual dimorphism
Gravid females show a fuller, broader outline when viewed from above.
Breeding
Use about two males per female, sponge filtration, and fine plants around 24 °C and pH 7. After dietary conditioning, a 50–70% cooler-water change with increased flow and aeration can help trigger spawning. A T-shaped pairing posture precedes batches of eggs being attached to glass or other surfaces. Separate eggs from adults to reduce predation. Incubate in aerated water from the spawning tank and remove fungal eggs. Hatching normally takes three to four days; small live foods follow yolk absorption. A thin sand layer appears useful for rearing.
