概述
三线豹鼠（Hoplisoma trilineatum）是温和、较耐养且常见的甲鲶，常被当作豹纹兵鲶（Hoplisoma julii）出售。花纹有变异，精确产地能帮助区分，不能把头部网纹和点纹当作绝对分界。
分布与栖息地
记录于哥伦比亚、秘鲁与巴西的部分亚马逊流域，以及苏里南若干沿海水系。栖于小支流、溪流、水塘和淹水森林。
饲养环境
小群可参考约 45 × 30 × 30 厘米。沙底、根部、沉木和干落叶配较暗灯光，及时换掉腐旧叶避免污染；维护良好的水草缸也可。底床洁净是重点，不采用底滤板，防止触须感染。
食性与喂食
杂食，以下沉颗粒或片剂为基础，补水蚤、丰年虾、红虫等活冷冻食物，不只依赖残饵。
习性与混养
至少六尾成群更好，性情温和，避开很大或攻击性伙伴，选择体型适合的温和鱼。
雌雄区分
雌鱼通常略大，从上方看体躯更宽圆，抱卵时最明显。
繁殖
通常较容易繁殖。一雌两雄，海绵过滤和细叶植物，参考水温 24 °C、酸碱度 6.5。抱卵后偏凉水换约 50%～70% 并增氧，卵分批黏于玻璃等处。产后分离亲鱼与卵，用原缸水充氧孵育并除霉卵。通常三至五天孵化，卵黄吸收后喂微虫或初孵丰年虾，薄沙底似有利于幼鱼健康。
补充说明
本种头部常为网状或蠕纹，但也有点状个体；真正豹纹兵鲶常见细点，两者仍需综合辨认。偶尔吞气为辅助呼吸，明显增频应查水质。胸鳍棘易挂网并可刺伤皮肤，转移时小心。

Overview
Hardy, peaceful Hoplisoma trilineatum is frequently sold as H. julii. Variable head patterns make the distinction less simple than a spotted-versus-reticulated rule; collection locality is useful when precise identification matters.
Distribution & habitat
Its reported range includes parts of the Amazon basin in Colombia, Peru, and Brazil, along with coastal systems in Suriname. Habitats include small tributaries, creeks, pools, and flooded forest.
Aquarium setup
A tank around 45 by 30 by 30 cm can use sand, roots, wood, and leaves under subdued light. Replace decaying leaves promptly. A planted layout can also work, provided maintenance is good. Keep the substrate clean and avoid undergravel filtration to protect the barbels.
Diet & feeding
Feed sinking pellets or tablets with varied live and frozen supplements. Direct feeding is needed for this omnivore.
Behaviour & compatibility
Keep at least six with peaceful, suitably sized companions. Avoid large or aggressive fishes.
Sexual dimorphism
Females are usually slightly larger and broader from above, particularly when gravid.
Breeding
Use two males per female with sponge filtration and fine plants around 24 °C and pH 6.5. A 50–70% cooler-water change and increased aeration can stimulate gravid females. Eggs attach to glass or other surfaces. Separate adults and eggs afterward and incubate in well-oxygenated breeding-tank water, removing fungal eggs. Hatching generally takes three to five days. Offer small live foods after yolk absorption and consider thin sand for rearing.
Notes
Reticulated or wormlike head markings are typical, but spotted individuals also occur. Compare several features with H. julii rather than relying on head markings alone. Occasional surface gulps supplement respiration. Check water quality if they become unusually frequent, and handle carefully around the net-snagging pectoral spines.
