概述
豹兵鲶（Brochis leopardus）是西亚马逊的斑点甲鲶，吻较长而尖，容易与花纹近似的短吻鼠鱼混淆。它温和、喜大群，搭配伙伴时也要照顾不高于约 25 °C 的饲养温度范围。
分布与栖息地
记录来自秘鲁、厄瓜多尔、玻利维亚与巴西的西亚马逊地区，包括亚瓦里、茹鲁阿、纳波及马努里皮水系。栖地有牛轭湖、潟湖、回水、泛滥平原湖和森林小溪。模式鱼来自水族贸易，所谓巴西沿海模式地点不确定，帕拉州及哥伦比亚的部分记录也仍待确认。
饲养环境
群养可参考约 60 × 38 × 30 厘米，细沙便于觅食，配平滑石块、沉木、密植区和浮水遮蔽。保持充氧和水面扰动，规律清洁底砂，不用底滤板，避免污底损伤触须。
食性与喂食
杂食，在底部找食。小型下沉颗粒或片剂可配红虫、水蚤、丰年虾等，确保足量食物到达底部，不只依赖上层鱼漏食。
习性与混养
理想为十尾或更多，同种多时通常更自信、活跃。可与体型合适的温和小鱼和其他温和鲶鱼搭配，避开大型或好斗鱼。伙伴应适应 25 °C 或更低的相宜温度。
雌雄区分
雌鱼更大且体躯圆宽，从上方看最清楚；成熟雄鱼鳍尖往往更尖。
繁殖
可借鉴近缘鼠鱼繁殖，但不能把借用的受精机制当作豹兵鲶实证。尝试一雌两雄，以活冷冻饵调理，雌鱼抱卵后做稍凉的大换水。若有卵附在玻璃或叶面，可分离亲鱼与卵，使用同缸水孵化并除去白色霉卵。幼鱼卵黄耗尽后可喂微虫、初孵丰年虾，并尝试薄沙底育苗。
补充说明
与 豹纹兵鲶（Hoplisoma julii）、三线兵鲶（Hoplisoma trilineatum） 相比，本种吻更长更尖、成体较大，相似外观不等于近缘程度相同。偶尔上浮吞气正常，频率突然升高需检查水质；胸鳍棘易挂网和刺伤，捕捞时要小心。
English
Overview
A longer pointed snout helps distinguish Brochis leopardus from similarly patterned short-snouted cory catfishes. This peaceful western-Amazon species benefits from a substantial group and companions comfortable within its relatively cool temperature range.
Distribution & habitat
Records cover western-Amazon localities in Peru, Ecuador, Bolivia, and Brazil, including the Javari, Juruá, Napo, and Manuripi systems. Habitats include oxbows, lagoons, backwaters, floodplain lakes, and forest streams. The type specimens were aquarium imports, leaving their original locality uncertain. Some coastal Pará and Colombian records remain unconfirmed.
Aquarium setup
A tank around 60 by 38 by 30 cm is suggested for a group. Use fine sand with smooth rocks, wood, dense planting, and some floating shade. Maintain oxygenation and surface movement, keep the substrate clean, and avoid undergravel filtration to protect the barbels.
Diet & feeding
This omnivore forages along the substrate. Offer small sinking pellets or tablets with live or frozen supplements, ensuring adequate food reaches the group.
Behaviour & compatibility
Ten or more is an ideal group, encouraging confidence and activity. Choose peaceful companions of appropriate size rather than large or aggressive fishes, and match their temperature needs to the species’ upper limit of about 25 °C.
Sexual dimorphism
Females are larger and rounder, best compared from above. Mature males tend to develop more pointed fin tips.
Breeding
A related-cory protocol may be tried rather than assumed proven for this species. Condition a group with about two males per female, then use a substantial slightly cooler-water change when females are gravid. If eggs are attached to glass or leaves, separate them from adults and incubate in water from the spawning tank, removing fungal eggs. Feed small live foods after yolk absorption and consider a thin sand layer for rearing. The detailed sperm-transfer mechanism demonstrated in another cory species should not be treated as established here.
Notes
Compared with Hoplisoma julii and H. trilineatum, it has a longer snout and larger adult size. Occasional surface gulps are normal, while an unusual increase can signal declining water quality. Pectoral spines can catch in netting or puncture skin.
