概述
瘦身鳅（Canthophrys gongota）是一种运输和适应阶段较脆弱的钻沙鳅。成熟、洁净的鱼缸与可自在埋身的软沙是基础，不能因它常藏在沙里就忽略群体互动和正常摄食。
分布与栖息地
广布尼泊尔、印度北部与孟加拉国的恒河、布拉马普特拉河水系。多见较浅而缓流的支流和小河，底质为泥、沙或砾石，水草不一定多，部分地点岸边植物浓密。
饲养环境
底面积至少参考 90 × 30 厘米，细软沙底不可缺。硬景先固定再铺沙，保留开阔沙地，弱光与落叶可提供安全感。粗砾可能造成应激、磨伤并抑制取食。只能引入成熟稳定缸，每周换约 30%～50%；含氧充足时水流强弱不是重点。
食性与喂食
以小型动物为主，通过筛砂取得昆虫幼虫和小甲壳类。可接受下沉干粮，但应规律提供水蚤、丰年虾、红虫等合口活冷冻饵。
习性与混养
至少六尾更合适，可见丰富互动。普通混养缸未必适合；温和中上层小鱼可能帮助减轻胆怯，其他钻沙鳅则需排除好斗或强领地种。
雌雄区分
幼鱼较难分性，雄鱼并没有很多鳅类常见的胸鳍圆盘结构。较老雌鱼明显更大，体形也似更厚。
补充说明
眼下棘可在受惊或离水时竖起，捞取时防止挂网与刺伤。

Overview
A delicate sand-burrowing loach, Canthophrys gongota can be difficult to transport and settle. An established clean aquarium and soft substrate are fundamental, while its hidden lifestyle should not obscure the need for social companions and dependable feeding.
Distribution & habitat
Its range spans the Ganges and Brahmaputra systems in Nepal, northern India, and Bangladesh. Shallow slow tributaries and smaller rivers have mud, sand, or gravel beds, with aquatic plants only occasionally present and dense bankside growth at some sites.
Aquarium setup
Use at least a 90 by 30 cm base and soft fine sand. Install stable hardscape before substrate, leaving open areas for burrowing. Dim light and leaves can add security. Coarse gravel may cause stress, injury, or feeding difficulties. Stock only a mature, stable tank and make weekly changes around 30–50%. With adequate oxygen, strong current is not essential.
Diet & feeding
It extracts tiny animal prey from substrate sifted through the gills. Sinking prepared foods can be accepted, but regular small live or frozen meals remain useful, including water fleas, brine shrimp, and insect larvae.
Behaviour & compatibility
Keep at least six for social interaction. A general community is not automatically appropriate. Quiet open-water fishes may reduce timidity, while other sand loaches need checking for aggressive or territorial behavior.
Sexual dimorphism
Young fish are difficult to sex because males lack the pectoral lamina found in many other cobitids. Older females become noticeably larger and apparently deeper-bodied.
Notes
Subocular spines may erect when stressed or lifted from water, posing a risk of net entanglement or injury.
