概述
平氏兵鲶(Brochis pinheiroi)是少见的温和甲鲶,花纹与一些常见鼠鱼相似,但缺少相似鱼的橙色胸鳍棘。它偏好较温暖的水,仍需良好充氧与洁净底床。
分布与栖息地
原生巴西朗多尼亚州。
饲养环境
可参考约 60 × 38 × 30 厘米,水温约 25~28 °C。细沙配平滑石、沉木和植物遮蔽,适当水流和水面扰动维持充氧。不要使用底滤板,脏底可能造成触须损伤。
食性与喂食
下沉干粮可搭配红虫、丰年虾和碎蚯蚓等小型活冷冻饵,保持多样投喂。
习性与混养
至少六尾同养通常更自信活跃,可与体型适合的温和小鱼和其他温和鲶鱼搭配,避开大型或好斗伙伴。
雌雄区分
成熟雌鱼从上方看体躯较圆宽,抱卵时更明显。
繁殖
可试近缘鼠鱼流程,一雌两雄、海绵过滤、细叶植物,参考水温 26 °C、酸碱度 6.5~7。调理至雌鱼抱卵后,用偏凉水换 50%~70% 并增氧。若产下附着卵,分开亲鱼与卵,用原缸水保持孵化充氧并除霉卵。三至四天孵化、卵黄吸收后吃微虫或丰年虾无节幼体及薄沙育苗,都应视为近缘方法参考而非该种已确定时程。
补充说明
与 斯特巴氏兵鲶(Hoplisoma sterbai) 花纹相近,但本种没有其橙色胸鳍棘,选购时应连同其他外观一起辨认。

Overview
Uncommon in the hobby, Brochis pinheiroi resembles some familiar patterned cory catfishes but lacks the orange pectoral spines of its close look-alike. Warm water, ample oxygen, and a clean substrate are important for its care.
Distribution & habitat
It is recorded from Rondônia in Brazil.
Aquarium setup
A suggested tank measures about 60 by 38 by 30 cm, at 25–28 °C. Combine fine sand with smooth rocks, wood, and plant cover. Maintain flow and surface movement, avoid undergravel filtration, and prevent waste accumulation that could damage the barbels.
Diet & feeding
Use sinking prepared foods with varied small live or frozen supplements, including brine shrimp and chopped earthworms.
Behaviour & compatibility
Keep at least six for confidence and activity. Peaceful small fishes and catfishes of compatible size are suitable candidates; avoid large or aggressive species.
Sexual dimorphism
Females show a fuller, broader outline when viewed from above, especially when gravid.
Breeding
A trial based on related corys can use two males per female, sponge filtration, and fine plants around 26 °C and pH 6.5–7. When females are gravid, attempt a 50–70% cooler-water change and increased aeration. If adhesive eggs are obtained, separate them from adults, incubate in aerated breeding-tank water, and remove fungal eggs. A three-to-four-day hatch, small live foods after yolk absorption, and thin-sand rearing are borrowed reference points, not proven timings for this species.
Notes
The absence of the orange pectoral spines seen in Hoplisoma sterbai helps distinguish the otherwise similar pattern.
