概述
灰兵鲶（Hoplisoma griseum）是圭亚那的温和群居鼠鱼。它的早期产地记载曾被修正，而数种外貌相似的编号鱼来自巴西，因此辨种时保留来源信息很有帮助。
分布与栖息地
原产圭亚那，可能局限于埃塞奎博河水系的波塔罗河。最初描述使用水族标本，所谓亚马孙小溪来源后来被修正，不能把旧说法当成已经确认的分布。
饲养环境
细砂底较适合，圆滑砾石也可，但须保持清洁。给鱼群提供遮蔽物形成安全感，并确保沉底食物能进入其觅食区域。
食性与喂食
杂食，接受沉底干粮及红虫、水蚯蚓等小型活饵、冷冻饵料。搭配多样食物并主动投喂，不依靠其他鱼的残饵，也不让所谓清洁功能取代日常维护。
习性与混养
温和且群居，至少四至六条同种一起养。混养时观察鱼群能否正常获得食物，而非只看有没有追逐争斗。
雌雄区分
雌鱼通常更大，成熟后身体更宽、体高更明显。
繁殖
可采用常见鼠鱼方法，每雌配两条或更多雄鱼。亲鱼调养成熟后，通过较凉换水、增加水流和供氧刺激。卵可附在缸壁、细叶植物或沉底拖把上，拖把便于移卵。
产后分开卵与亲鱼，孵化容器保持相同水质及充足供氧。约三至四天孵化，卵黄吸收后喂微虫或丰年虾无节幼体。幼鱼需要非常好的水质，薄砂底似乎比裸底更有利于健康。
补充说明
巴西的 C040、C073、C134 等鱼外观相似，但相似不等于同种。偶尔上浮吞气属于辅助呼吸，胸鳍硬刺可挂网或刺伤皮肤，转移时避免直接挤压。

Overview
Hoplisoma griseum is a peaceful social catfish from Guyana. Its early locality information was corrected, while several visually similar numbered fishes come from Brazil. Keeping track of origin is therefore useful when assessing identity.
Distribution & habitat
It is native to Guyana and may be restricted to the Potaro within the Essequibo system. The original description used aquarium specimens with an alleged Amazon origin, subsequently corrected to the Potaro. The earlier account should not be treated as confirmed range information.
Aquarium setup
Use fine sand or carefully maintained rounded gravel. Provide shelter for security while leaving access to sinking food. Regular substrate cleaning remains necessary.
Diet & feeding
Offer varied sinking dry foods with small live or frozen supplements such as bloodworms and Tubifex. This omnivorous fish requires direct feeding. Leftovers and expectations of a clean aquarium are not an adequate maintenance plan.
Behaviour & compatibility
Keep at least four to six conspecifics. Its peaceful group behavior should be accompanied by reliable feeding opportunities, even where no overt aggression occurs.
Sexual dimorphism
Females usually become larger, broader, and deeper-bodied at maturity.
Breeding
Standard cory methods can be used with two or more males per female. Once adults are conditioned, cooler water changes and increased oxygenation and current can encourage spawning. Eggs may attach to glass, fine plants, or submerged mops, which facilitate removal.
Separate eggs and adults afterward. Maintain matching, well-oxygenated water during incubation. Hatching typically takes three or four days. Following yolk absorption, feed microworms or brine shrimp nauplii. Fry demand excellent water quality and appear less prone to problems over thin sand than over a bare floor.
Notes
Brazilian fishes coded C040, C073, and C134 look similar without necessarily representing this species. Occasional air gulps support auxiliary respiration. Stiff pectoral spines can snag nets or puncture skin, so transfers require care.
