概述
印记兵鲶（Hoplisoma metae）体后斜暗带在尾鳍基部结束，不延入尾鳍，也不在尾柄分叉，体侧没有额外暗斑。它温和群居，适合洁净底床与有遮蔽的布局。
分布与栖息地
哥伦比亚东部梅塔河上游特有，记录涉及胡梅阿、奥科阿、瓜蒂基亚等支流。梅塔河下游似缺少本种，也未记录于委内瑞拉；模式地点对应胡梅阿河上的巴里贡港。
饲养环境
长期底面积宜至少约 80 × 30 厘米。细沙较好，洁净圆滑砾石也可，并提供足够遮蔽。
食性与喂食
杂食，可给下沉干粮与小型活冷冻饵，保持多样和直接投喂。不要依赖其他鱼残饵。
习性与混养
至少四至六尾成群，性情温和。
雌雄区分
雌鱼通常长得更大，成熟后身体更圆宽，抱卵时尤其明显。
繁殖
可一雌两雄，抱卵后试偏凉水换约 50%～70%，同时增氧、增加水流。卵一般黏在玻璃，也可放细叶植物或产卵拖把。产后分离亲鱼与卵，用原缸水充氧孵育，观察并处理霉卵。通常三至四天孵化，卵黄吸收后喂微虫或初孵丰年虾；幼鱼需好水质，薄沙底似有益。
补充说明
背带形态有助与梅氏兵鲶等相似鱼区分，但选购仍应保留产地信息。偶尔上浮吞气可辅助呼吸；胸鳍棘能刺伤，基部腺体分泌物可能有轻微毒性，应谨慎搬动。

Overview
The rear oblique stripe of Hoplisoma metae stops at the tail-fin base, without splitting at the peduncle or extending onto the fin. No additional dark body markings are present. This peaceful social catfish benefits from shelter and a clean substrate.
Distribution & habitat
It is endemic to the upper Meta system in eastern Colombia, with records from tributaries including the Humea, Ocoa, and Guatiquía. It appears absent from the lower Meta and has not been recorded in Venezuela. The type locality corresponds to Puerto Barrigon on the Humea.
Aquarium setup
Provide at least an 80 by 30 cm footprint for long-term care, with fine sand or clean rounded gravel and suitable cover.
Diet & feeding
Feed varied sinking foods and small live or frozen supplements directly. This omnivore needs more than community leftovers.
Behaviour & compatibility
Maintain at least four to six together to support its peaceful social habits.
Sexual dimorphism
Mature females are generally larger and broader, especially when gravid.
Breeding
Use two males per female. Cooler-water changes of 50–70% with increased flow and aeration can encourage gravid females. Glass is the usual egg site, with fine plants and spawning mops as alternatives. Separate eggs from adults and incubate in aerated breeding-tank water, watching for fungus. Hatching generally takes three to four days; offer small live foods after yolk absorption. Excellent water quality and a thin sand layer favor rearing.
Notes
Stripe structure helps separate it from similarly marked species such as H. melini. Retain locality details when available. Occasional air gulps supplement respiration. Pectoral spines can puncture skin, and gland secretions may be mildly toxic, so handle carefully.
