概述
纳特兵鲶（Hoplisoma nattereri）需要约 20～23 °C 的偏凉环境，这比许多常见热带鱼低。它虽然温和易混养，伙伴温度需求仍必须一致，不能只看性情。
分布与栖息地
原生巴西沿海地区，范围由圣埃斯皮里图至巴拉那，栖于小支流、溪流、淹水森林及沙洲环境。
饲养环境
小群可参考约 45 × 30 × 30 厘米。河沙、沉木根部和干落叶配较暗光线，可让水略呈茶色；及时更换腐旧叶以免污染。也可用维护良好的水草缸，但不采用底滤板，保持底床洁净以防触须感染。是否需加热要看实际室温能否稳定在适宜范围。
食性与喂食
杂食，以优质下沉颗粒或片剂为基础，辅以水蚤、丰年虾、红虫等活冷冻食物，确保群体获得自己的食物。
习性与混养
至少六尾同养较好。避开大型、好斗或需要长期高温的鱼，可配适应凉水的温和伙伴。
雌雄区分
雌鱼往往略大，从上方看体躯宽圆，抱卵时最明显。
繁殖
可一雌两雄，以海绵过滤和细叶植物布置，参考水温 21 °C、酸碱度 6.5。雌鱼抱卵后用偏凉水换约 50%～70%，并增氧和加强水流。卵分批黏在玻璃等表面，产后移开亲鱼或卵，孵化水用原缸水并充氧、除霉卵。通常三至五天孵化，卵黄吸收后喂微虫或丰年虾无节幼体；薄沙底似有利于育苗。
补充说明
偶尔吞气为辅助呼吸，频率异常升高时需检查水质。胸鳍硬棘易挂网和刺伤，转移时应避免拉扯或徒手挤压。

Overview
The cool preference of Hoplisoma nattereri, around 20–23 °C, is a major stocking consideration. Peaceful behavior alone is insufficient for compatibility if companions need warmer water.
Distribution & habitat
It is native to Brazilian coastal regions from Espírito Santo to Paraná. Habitats include smaller tributaries, creeks, flooded forest, and sandy banks.
Aquarium setup
A small group can use a setup around 45 by 30 by 30 cm. Sand, wood, roots, and leaves under subdued light are suitable, or use a carefully maintained planted tank. Replace decaying leaves and keep the substrate clean; avoid undergravel filtration. An unheated setup is appropriate only when room conditions maintain suitable temperatures.
Diet & feeding
Use sinking pellets or tablets as the staple, with varied live and frozen supplements. Feed this omnivore directly rather than depending on leftovers.
Behaviour & compatibility
Keep at least six and choose peaceful companions comfortable in similarly cool water. Avoid large or aggressive fishes and warm-water specialists.
Sexual dimorphism
Females tend to be slightly larger and broader from above, particularly when carrying eggs.
Breeding
Use about two males per female with sponge filtration and fine plants around 21 °C and pH 6.5. A 50–70% cooler-water change with extra aeration can stimulate gravid females. Eggs are attached to glass or similar surfaces. Separate eggs and adults afterward, using aerated breeding-tank water and removing fungal eggs. Hatching usually takes three to five days. Offer small live foods after yolk absorption and consider a thin sand layer for rearing.
Notes
Occasional surface gulps supplement respiration; unusually frequent trips warrant a water-quality check. Pectoral spines may snag netting or puncture skin, so handle transfers carefully.
