概述
神兵鲶（Hoplisoma atropersonatum）是温和群居的鼠鱼，头部暗斑和体侧斑点使它容易与其他斑点型鼠鱼混淆。购买及繁殖时应关注完整体形、吻长与斑点分布，不要只看商品标签。
分布与栖息地
已知分布于厄瓜多尔和秘鲁的蒂格雷河、纳奈河水系。纳奈河完全位于秘鲁洛雷托地区，蒂格雷河则向北延伸进入厄瓜多尔。
饲养环境
细砂是较好的底床选择，圆滑砾石也可使用，但要保持清洁。布置适当遮蔽物提供安全感，避免底部积污影响长期状态。
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。食谱要丰富，投喂时确保鱼群吃到足够食物，不能只依靠混养伙伴的残饵。
习性与混养
性情温和，至少四至六条同种共同饲养。群居需求不等于清洁功能，底床仍需日常维护。
雌雄区分
雌鱼通常更大，成熟后体形明显较宽、较圆，怀卵时尤其突出。
繁殖
可用鼠鱼常见的方法繁殖，雄鱼略多较好，例如一雌配两雄。亲鱼充分调养后，用较凉的换水配合增加供氧和水流刺激产卵。卵通常粘在缸壁，也可提供细叶植物或产卵拖把。
产后分开亲鱼与卵，转移卵时维持相同水质和良好供氧。约三至四天孵化，卵黄消耗后可喂微虫或丰年虾无节幼体。薄砂底似乎比裸缸更有助于幼鱼健康，仍需保持水质。
补充说明
编号 C097 的相似鱼吻较长，斑点更清楚、间距更大，不能因同样带斑就混为一类。偶尔上浮吞气属于辅助呼吸，胸鳍硬刺可挂网或刺伤皮肤，转移时应小心操作。

Overview
Hoplisoma atropersonatum is a peaceful social catfish whose dark head markings and spotted body can resemble other cory-type fishes. Identification should consider the whole outline, snout length, and arrangement of spots rather than a sales label alone.
Distribution & habitat
It is recorded from the Tigre and Nanay drainages in Ecuador and Peru. The Nanay lies entirely within Peru's Loreto region, while the Tigre extends north into Ecuador.
Aquarium setup
Fine sand is preferable. Smooth rounded gravel is an alternative when kept thoroughly clean. Provide cover for security and prevent waste from accumulating around the bottom.
Diet & feeding
Use varied sinking dry foods with small live and frozen items, including bloodworms and Tubifex. This omnivorous feeder needs its own food supply; scraps left by companions are not sufficient.
Behaviour & compatibility
Keep at least four to six conspecifics together. Its peaceful, gregarious nature supports group maintenance, but keeping catfish does not remove the need to clean the substrate.
Sexual dimorphism
Females generally grow larger and become wider and rounder at maturity, most conspicuously when carrying eggs.
Breeding
Common cory breeding methods can be used, with approximately two males per female. Once adults are conditioned, cooler water changes and increased oxygenation and flow can stimulate spawning. Glass is a usual egg-deposition surface; offer fine plants or mops as alternatives.
Separate the adults and eggs afterward. Transferred eggs require matching water and good oxygenation. Incubation typically takes three or four days. Once yolk reserves are exhausted, fry can take microworms or brine shrimp nauplii. A thin sand layer appears to reduce health problems compared with a bare base, while water quality remains essential.
Notes
The similar fish coded C097 has a longer snout and clearer, more widely spaced spots. Occasional surface gulps provide auxiliary breathing. Stiff pectoral spines may catch in netting or puncture skin, so handle transfers carefully.
