概述
奥亚波河兵鲶（Hoplisoma oiapoquense）与一种几乎相同花纹的长吻近缘鱼在野外共同游群，辨认不能只看花色。它温和合群，雌雄体宽差异也没有很多鼠鱼那么明显。
分布与栖息地
分布于法属圭亚那与巴西的奥亚波克河，目前采集记录来自河流上游。
饲养环境
可参考约 45 × 38 × 30 厘米，细沙配平滑石、沉木和植物遮蔽。保持充氧和适当水流、水面扰动，不用底滤板，底床清洁有助避免触须损伤。
食性与喂食
下沉干粮可搭配红虫、丰年虾和切碎蚯蚓等小型活冷冻食物，食谱应多样。
习性与混养
至少六尾成群更自信活跃，适合体型合适的温和伙伴，避开很大或好斗鱼。
雌雄区分
雌鱼通常更大，但不如许多鼠鱼那样明显宽体，因此仅凭俯视体宽较难分性别。
繁殖
可一雌两雄，用海绵过滤及细叶植物，参考水温 25 °C、酸碱度 6.5～7。抱卵后偏凉水换 50%～70% 并增氧可诱发产卵。卵分批附在玻璃等处，产后移开亲鱼或卵，用原缸水保持充氧并除霉卵。通常三至四天孵化，卵黄吸收后喂微虫或初孵丰年虾；薄沙底似有助减少幼鱼问题。
补充说明
近似的 长吻近缘鱼 吻更长，在奥亚波克河内分布也更广，两者可同群出现。后者分布更广不能用于扩大本种上游记录的范围。

Overview
Wild Hoplisoma oiapoquense can share schools with a nearly identical-looking, longer-snouted relative. Color alone is therefore an unreliable identification guide. It is peaceful and social, with less obvious sex differences in body width than many cory catfishes.
Distribution & habitat
It occurs in the Oyapock system shared by French Guiana and Brazil, with collections confined to the upper river.
Aquarium setup
A suggested tank is about 45 by 38 by 30 cm. Use fine sand with smooth stones, wood, and plant cover. Maintain oxygenation, flow, and surface movement. Avoid undergravel filtration and keep the substrate clean to protect the barbels.
Diet & feeding
Combine sinking prepared foods with varied small live or frozen items, such as brine shrimp and chopped earthworms.
Behaviour & compatibility
Keep at least six for confidence and activity. Choose peaceful companions of appropriate size rather than large or aggressive fishes.
Sexual dimorphism
Females tend to grow larger, but their bodies do not broaden as markedly as in many related species, making sexing more difficult.
Breeding
Use two males per female, sponge filtration, and fine plants around 25 °C and pH 6.5–7. A 50–70% cooler-water change and extra aeration can encourage gravid females. Eggs are attached in batches to glass or other surfaces. Separate eggs from adults and incubate in aerated breeding-tank water, removing fungal eggs. Hatching normally takes three to four days. Small live foods follow yolk absorption, and a thin sand layer appears helpful for rearing.
Notes
The look-alike Brochis condiscipulus has a longer snout and a wider Oyapock distribution. Mixed schooling occurs, but its wider range should not be attributed automatically to H. oiapoquense.
