概述
秘鲁兵鲶（Hoplisoma loretoense）标准体长约 5 厘米，长背鳍棘是醒目外观。它温和且喜同种群体，清洁细底床和充氧比把它当清洁鱼更重要。
分布与栖息地
原生秘鲁的上亚马逊地区。
饲养环境
可参考约 45 × 38 × 30 厘米，细沙配平滑岩石、沉木、密植区和浮水遮蔽。保持适度水流与水面扰动，避免底滤板并维持底床洁净，以防触须受损。
食性与喂食
可喂下沉干粮，配红虫、丰年虾和碎蚯蚓等小型活冷冻食物。确保群体获得食物，不仅依靠上层鱼漏食。
习性与混养
至少六尾同养，通常会更自信活跃。可与合适温和小鱼和其他温和鲶鱼混养，避开很大或好斗伙伴。
雌雄区分
雌鱼往往比雄鱼大，抱卵时从上方看身体宽圆。
繁殖
可按常见鼠鱼方法繁殖，一雌两雄，用海绵过滤和细叶植物，参考水温 24 °C、酸碱度约 7。抱卵后偏凉水换约 50%～70%，并增氧加强水流。产卵时有丁字姿势，雌鱼分批把卵黏在玻璃等处。成鱼可能吃卵，应产后分离，孵化水用原缸水并充氧，移除霉卵。卵常三至四天孵化，卵黄吸收后喂微虫或初孵丰年虾，薄沙底似有助育苗。
补充说明
偶尔上浮吞气是辅助呼吸行为，明显增加时需结合水质检查。胸鳍硬棘易挂网并可刺伤皮肤，搬动时应避免拉扯或握压。

Overview
A long dorsal spine is a striking feature of Hoplisoma loretoense, a cory catfish reaching about 5 cm standard length. Its peaceful social habits call for a group, a clean fine substrate, and good oxygenation.
Distribution & habitat
It is recorded from the upper Amazon region of Peru.
Aquarium setup
A suggested tank is about 45 by 38 by 30 cm. Use fine sand, smooth stones, wood, plants, and floating shade. Maintain flow and surface movement, avoid undergravel filtration, and keep the substrate clean to protect the barbels.
Diet & feeding
Offer sinking prepared foods with varied small live or frozen items. Make sure the group receives food directly rather than depending on scraps from fishes above.
Behaviour & compatibility
Keep at least six for confidence and activity. Peaceful small fishes and catfishes of suitable size are better companions than large or aggressive species.
Sexual dimorphism
Females tend to be larger, with a rounded, broader outline most evident from above when gravid.
Breeding
Use about two males per female with sponge filtration and fine plants around 24 °C and pH 7. A 50–70% cooler-water change with extra aeration can encourage gravid females to spawn. T-shaped pairing precedes successive eggs being attached to glass or other surfaces. Separate eggs from adults afterward and incubate in aerated breeding-tank water, removing fungal eggs. Hatching usually takes three to four days; small live foods follow yolk absorption. A thin sand layer appears useful for rearing.
Notes
Occasional surface gulps provide supplementary respiration, while an unusual increase warrants checking water quality. Pectoral spines can snag netting or puncture skin, so avoid pulling an entangled fish or gripping it directly.
