概述
格里氏兵鲶（Brochis geryi）是较少见的甲鲶，成体约 7 厘米，性情十分温和。它需要同种伙伴、洁净细底床和较高溶氧，不能只作为混养缸的清洁鱼。
分布与栖息地
原生于玻利维亚马莫雷河流域。
饲养环境
可参考约 60 × 38 × 30 厘米，细沙底配平滑岩石、沉木、密植区和浮水遮蔽。保持适度水流和水面扰动，不使用底滤板；污浊底床可能损伤触须，应特别注意清洁。
食性与喂食
可接受下沉干粮，搭配红虫、丰年虾或切碎蚯蚓等小型活冷冻食物。让饵料确实到达鱼群，不要只等上层鱼漏下残饵。
习性与混养
至少六尾较合适，有同种伙伴时通常更自信、更活跃。避开过大或好斗伙伴，可考虑体型合适的温和小鱼与其他温和鲶鱼。
雌雄区分
从上方看更容易分辨，雌鱼通常更宽圆，抱卵时尤其明显。
繁殖
可借鉴近缘鼠鱼方法尝试，不能把这一方案视作本种已验证结果：一雌配两雄，用海绵过滤和细叶遮蔽，参考水温 24 °C、酸碱度 6.5～7。抱卵明显后可试偏凉水换 50%～70% 并增氧。若获得玻璃或植物上的附着卵，可移开亲鱼或转卵至同缸水孵育，维持充氧并及时除霉卵。近缘种常在三至四天孵化，卵黄吸收后喂微虫和丰年虾无节幼体；薄沙底可作为育苗尝试。
补充说明
偶尔上浮吞气属于辅助呼吸；若频率明显增加，应结合水质检查。胸鳍棘容易挂网，也能刺伤皮肤，搬动时应避免拉扯或徒手握压。

Overview
An uncommon cory catfish reaching about 7 cm, Brochis geryi is very peaceful. Conspecific company, clean fine substrate, and well-oxygenated water are central to its care.
Distribution & habitat
It is native to the Mamoré drainage in Bolivia.
Aquarium setup
A tank around 60 by 38 by 30 cm is suggested. Use fine sand with smooth rocks, wood, planting, and floating cover. Provide flow and surface movement, and avoid undergravel filtration. Dirty substrate can damage barbels, making regular maintenance especially important.
Diet & feeding
Sinking prepared foods can be varied with small live or frozen items, including brine shrimp and chopped earthworms. Ensure the group receives food directly rather than relying on scraps drifting down from other fishes.
Behaviour & compatibility
Keep at least six; conspecific company encourages confidence and activity. Avoid large or aggressive companions and choose peaceful fishes of suitable size.
Sexual dimorphism
A view from above best shows the broader, rounder body of females, especially when gravid.
Breeding
A related-cory breeding method can be tried, but it is not an established protocol for this species. Use two males per female, sponge filtration, and fine vegetation around 24 °C and pH 6.5–7. When females are gravid, a 50–70% cooler-water change with increased oxygenation may encourage spawning. If adhesive eggs are obtained, separate them from adults, incubate in aerated water from the spawning tank, and remove fungal eggs. Related species often hatch in three to four days and take small live foods after yolk absorption. A thin sand layer is one possible rearing approach.
Notes
Occasional surface gulps are normal supplementary breathing, but a marked increase warrants a water-quality check. Pectoral spines can catch in net mesh or puncture skin, so avoid pulling an entangled fish or gripping it directly.
