概述
饰妆条鳅（Nemacheilus ornatus）的体侧黑色纵纹上，分布着向上下伸展的暗斑，前方第一块暗斑外有浅色环。它是温和而较隐蔽的小鳅，适合富氧、有遮蔽的群体饲养环境。
分布与栖息地
已知仅见于泰国南部素叻他尼府的达比河流域。虽然这条河发源于邻近府域，不能据此把本种分布扩展到整个源头区域。
据描述，它生活在清澈、流速中等的浅滩，底部有小卵石。
饲养环境
底面积约 60 × 30 cm 起步，以砂、细砾及不同大小的圆石搭建溪流式底床，枝木形成洞缝、阴影与视线屏障。耐受水草可以固定在硬景上。
保持高溶氧和适当水流即可，无须猛烈激流。它不耐有机污物积累，每周换水约三至五成应成为固定维护。
食性与喂食
同属鱼总体为动物性食物占主导的杂食者，小昆虫、蠕虫、甲壳类和其他浮游动物占较多，少量植物还可能经猎物胃内容物进入食物链。缸内宜用适口干粮搭配每日水蚤、丰年虾、红虫等小型活饵或冷冻饵。
习性与混养
至少四条同养较合适。适应相似环境的温和开阔水域鱼群有助于它安心露面，合适的喜流鳅和底栖鲤科鱼也可考虑。与外形相近的强势条鳅混养风险较高，只有较大空间才值得谨慎尝试。
雌雄区分
雄鱼眼下有皮瓣，前四条胸鳍支条增粗并有数排小结节，繁殖状态时可能更明显。雌鱼可能略大、更粗壮。
补充说明
体侧通常有九至十六块纵向暗斑横跨黑色侧带，背部另有不规则暗纹。前方眼状斑应与其他斑纹一起观察，不能只靠单个斑点认种。

Overview
Nemacheilus ornatus has a dark flank stripe crossed by vertical blotches, with a pale ring around the first blotch. This peaceful, retiring loach suits a well-oxygenated aquarium with ample cover and companions of its own kind.
Distribution & habitat
The known range is restricted to the Tapi drainage in Surat Thani, southern Thailand. The river's headwaters extend beyond that province, but the fish has not been reported throughout the entire upstream area.
It is said to inhabit shallow riffles with clear, moderately flowing water over small pebbles.
Aquarium setup
Start with a footprint of roughly 60 × 30 cm. Sand, fine gravel, and rounded stones of varied sizes create a stream-like bottom. Branching wood should supply crevices, shade, and broken sight lines. Hardy plants can be attached to the structure.
Maintain high oxygen levels and some circulation; torrential flow is unnecessary. Avoid organic waste accumulation and make weekly changes of about 30–50 percent part of routine care.
Diet & feeding
The genus generally consumes an animal-dominated mixed diet, including small insects, worms, crustaceans, and other zooplankton. Some plant material enters through prey stomach contents. Offer suitable dry foods plus daily small live or frozen meals such as water fleas, brine shrimp, and bloodworms.
Behaviour & compatibility
Keep at least four together. Peaceful open-water fishes with matching environmental needs can encourage this loach to emerge. Suitable current-loving loaches and bottom-dwelling cyprinids are other options. Strongly territorial lookalikes are a risk and should only be considered cautiously in larger spaces.
Sexual dimorphism
Males have a flap below the eye and thickened first four branched pectoral rays bearing several rows of tubercles, potentially more prominent in breeding condition. Females may grow a little larger and heavier-bodied.
Notes
Nine to sixteen vertical blotches typically cross the lateral stripe, and the dorsal stripe is irregular. Evaluate the anterior eyespot with the entire marking pattern rather than using it alone for identification.
