概述
冈瑟氏中间真条鳅（Mesonoemacheilus guentheri）来自印度西高止山地，体侧有一列列带深色边缘的浅黄色圆斑。个体在水族箱中的表现差异很大，既有温和的饲养记录，也有强烈守域与攻击记录，混养不能只按“小型鳅”看待。
分布与栖息地
最早描述于印度南部泰米尔纳德邦尼尔吉里山坡的急流，后来也在更南方喀拉拉邦的豆蔻山地区发现。不同种群之间，甚至同一种群内部，颜色和斑纹也会有变化。
栖息在清澈、富氧的源头溪流和小河，岸边森林常形成遮阴。底部包括粗砂、砾石和大石，表面有藻类及其他微生物。季风期水流和浑浊度会明显增加。
饲养环境
底面积至少约 60 × 30 cm，用大小石块、砂砾和枝木搭建许多洞缝、阴影与视线阻隔，耐受植物可附着在硬景上。保持高溶氧和适当水流，不必制造猛烈激流。每周换水约三至五成，避免有机污物积累。
食性与喂食
中间真条鳅属属于杂食，主要食物是小昆虫、蠕虫、甲壳类及其他浮游动物，植物占较小部分。本种可接受适口干饲料，但应每天搭配水蚤、丰年虾、红虫等小型活饵或冷冻饵。
习性与混养
攻击性的差异原因尚不清楚，可能与种群、性别或环境有关。优先选择适应相似水环境、较强健的开阔水域鱼；浅缸里尤其不宜搭配太小或脆弱的鱼，以免无处躲避持续追逐。
避免过于安静的底栖鱼以及体形相近的条鳅，合适的喜流鱼也需观察互动。通常能容忍同类，建议至少四条，但仍须留意可能出现的强烈领域行为。
雌雄区分
雄鱼眼下有小皮瓣，成熟时胸鳍条可能增粗并出现成排小结节。雌鱼可能略大，抱卵时腹部较圆。
补充说明
辨识时可留意圆形而非分叉的体斑、较长尾柄和尾柄暗带，以及臀鳍不达尾鳍基部。贸易中常作为近似种的混入个体出现，不能把所有黄斑个体都视为同种。

Overview
Mesonoemacheilus guentheri is a Western Ghats loach with rows of pale yellow, dark-edged round spots. Aquarium reports range from peaceful behavior to pronounced territorial aggression, so compatibility needs individual assessment.
Distribution & habitat
It was described from rapids on the Nilgiri Hills in Tamil Nadu, southern India, and has subsequently been recorded farther south in Kerala's Cardamom Hills. Color and markings vary both between and within populations.
Habitats are clear, oxygenated headwater streams and small rivers, often shaded by forest. Coarse sand, gravel, and large stones form the bottom, with algae and microorganisms growing on exposed surfaces. Monsoon conditions markedly increase flow and turbidity.
Aquarium setup
Provide at least about 60 × 30 cm of floor space. Stones, sand, gravel, and branching wood should create numerous shaded crevices and interrupted sight lines. Hardy plants may be attached to the structure. Maintain high oxygen levels and useful circulation without needing torrential flow. Weekly changes of around 30–50 percent help prevent organic waste accumulation.
Diet & feeding
Members of this genus are omnivorous, eating predominantly small insects, worms, crustaceans, and other zooplankton, with a smaller plant component. Offer appropriately sized dry food alongside daily small live or frozen items such as water fleas, brine shrimp, and bloodworms.
Behaviour & compatibility
The reasons for contrasting aggression reports remain unresolved; population, sex, and environment may contribute. Robust open-water fishes with matching environmental needs are the better candidates. Avoid tiny or delicate companions, especially in shallow aquariums where persistent chasing may leave little refuge.
Very placid bottom dwellers and similarly shaped loaches are poor choices. Suitable current-loving fishes still require observation. Groups of at least four are recommended because the species normally tolerates its own kind, although extreme territorial behavior can occur.
Sexual dimorphism
Males have a small flap below the eye and may develop thickened pectoral rays bearing rows of tubercles. Females may grow slightly larger and develop a rounder abdomen when carrying eggs.
Notes
Round rather than forked spots, a relatively long caudal peduncle with a dark band, and an anal fin that does not reach the tail base help identify this loach. Mixed shipments can contain similar species.
