概述
亚氏兵鲶（Hoplisoma axelrodi）是哥伦比亚的群居鼠鱼，体侧深色纵纹可有一至三条，外观变化较大。数种相似鱼曾共用相同商品标签，辨种不能只看有没有纵纹。
分布与栖息地
似乎为哥伦比亚梅塔河水系特有，具体采集地点仍不充分。模式地点可能在梅塔省的马纳卡西亚斯河流域，这一定位仍带推测性质。
饲养环境
用细砂铺底较合适，圆滑砾石也可，但清洁要求不应降低。适当遮蔽能提供安全感，底部应留出便于鱼群觅食的空间。
食性与喂食
杂食，接受沉底干粮与红虫、水蚯蚓等小型活饵、冷冻饵料。用多样食物维持状态，确保沉底食物真正到达鱼群，而非让它只拾取其他鱼的残饵。
习性与混养
温和且喜欢同伴，至少四至六条同种一起饲养。群体应有充分摄食机会，不能把它们当成可以替代人工维护的清洁队。
雌雄区分
雌鱼通常更大，成熟后更宽圆，怀卵时尤其容易看出差别。
繁殖
可用常见鼠鱼繁殖方法，一雌配约两雄。调养好亲鱼后，可通过较凉换水、增加供氧及水流诱导。卵常附在缸壁，细叶植物与产卵拖把也可作为附卵位置。
产后分开卵与亲鱼，转移时保持水质一致并有良好供氧。孵化一般约三至四天，卵黄消耗完再用微虫或丰年虾无节幼体开口。薄砂底似乎有助于降低幼鱼健康问题，不能据此放松水质管理。
补充说明
主纵纹位于体侧中部，若有第二、第三条纹，常破碎成斑块。编号 C003、CW021 等相似鱼的条纹位置与连续性不同；「deckeri」等商品名不能当作可靠种名。偶尔上浮吞气正常，胸鳍硬刺容易挂网及刺伤，转移时避免挤压。

Overview
The Colombian catfish Hoplisoma axelrodi varies in appearance, with one to three dark stripes along each side. Several similar fishes have shared commercial labels, making the mere presence of stripes insufficient for identification.
Distribution & habitat
It appears endemic to Colombia's Meta drainage, although precise collection information is scarce. A proposed location in the Manacacias basin remains an inference rather than a settled locality.
Aquarium setup
Use fine sand where possible. Rounded gravel is acceptable if kept meticulously clean. Shelter provides security, while open feeding areas let the group obtain sinking foods.
Diet & feeding
Offer an omnivorous range of sinking dry foods and small live or frozen items such as bloodworms and Tubifex. Feed deliberately and check access. Uneaten scraps from other fishes should not be its principal food supply.
Behaviour & compatibility
Maintain at least four to six together. These peaceful, social catfish need conspecific company and dependable feeding opportunities. They do not replace routine substrate maintenance.
Sexual dimorphism
Females tend to grow larger and become broader and rounder when mature, particularly when carrying eggs.
Breeding
Standard cory breeding methods are applicable, using roughly two males per female. After conditioning adults, cooler water changes with greater oxygenation and flow can stimulate spawning. Eggs commonly attach to glass; fine plants and spawning mops offer additional surfaces.
Separate the eggs from adults after spawning. Any transfer should preserve water conditions and oxygenation. Hatching normally takes three or four days. After yolk absorption, provide microworms or brine shrimp nauplii. Fry appear less prone to problems over a thin sand layer, but clean water remains essential.
Notes
The main stripe lies around midbody. Additional stripes, when present, commonly break into blotches. Similar fishes coded C003 and CW021 differ in stripe position or continuity, while labels such as deckeri do not establish a valid identity. Occasional air gulps are normal. Pectoral spines can snag netting and puncture skin during handling.
