概述
同色兵鲶（Hoplisoma concolor）具有较均一的灰色体色、较高身体及大眼，成熟雄鱼背鳍会明显延长。它温和群居，适合以同种小群维持，而不是单独作为清洁鱼。
分布与栖息地
分布限于委内瑞拉西部奥里诺科河水系的部分区域，模式地点在帕尔瓜萨河的一条支流。
饲养环境
细砂底较合适，圆滑砾石也可，但要保持清洁。提供适当遮蔽，让鱼群有安全感，并留出方便摄食的底部空间。
食性与喂食
杂食，沉底干粮搭配红虫、水蚯蚓等小型活饵和冷冻饵料较合适。不能靠其他鱼的残饵维持，也不能把它的觅食当成无需清理底床的理由。
习性与混养
温和且喜欢同伴，至少四至六条同种一起养。混养时需保证它们能获得足够食物。
雌雄区分
成熟雄鱼背鳍延长。雌鱼通常更大，身体更宽圆，怀卵时差别尤其明显，判断时可结合两种特征。
繁殖
卵通常附在缸壁或细叶植物上。产后卵可留在原处，也可转入水质相同、供氧充分的容器。一般约三至四天孵化，卵黄吸收完后可喂微虫及丰年虾无节幼体。
薄砂底似乎比裸缸更有利于幼鱼健康。
补充说明
均一灰色、较高体形、大眼和较长背鳍硬刺应合并观察，不能仅凭某一处外观确认身份。偶尔上浮吞气属于辅助呼吸，胸鳍硬刺可挂住网具或刺伤皮肤，转移时小心操作。

Overview
Hoplisoma concolor combines a largely uniform gray appearance with a deep body and large eyes. Mature males develop an extended dorsal fin. Peaceful and social, it belongs in a conspecific group rather than as a solitary cleanup fish.
Distribution & habitat
It is restricted to parts of the Orinoco system in western Venezuela. The type locality lies in a tributary of the Parguaza.
Aquarium setup
Fine sand is preferable. Smooth gravel can be used when kept clean. Provide cover for security and leave accessible areas where the group can feed.
Diet & feeding
Supply a varied omnivorous diet of sinking prepared foods and small live or frozen items, including bloodworms and Tubifex. Deliberate feeding is necessary; scraps from companions and routine bottom foraging cannot replace proper nutrition or maintenance.
Behaviour & compatibility
Keep at least four to six together. Its peaceful, gregarious behavior still requires attention to feeding access in a shared aquarium.
Sexual dimorphism
Mature males develop a longer dorsal fin. Females are generally larger and broader, especially when carrying eggs. Consider both features when assessing sex.
Breeding
Eggs usually attach to glass or fine-leaved plants. They may remain where laid or be transferred into matching, well-oxygenated water. Incubation usually takes three or four days. After yolk absorption, fry can take microworms and brine shrimp nauplii.
A thin sand layer appears preferable to a bare base for reducing fry health problems.
Notes
The uniform gray pattern, body depth, large eyes, and long dorsal spine are most useful together. Occasional surface gulps support auxiliary breathing. Pectoral spines can catch in netting and puncture skin, so transfers require care.
