概述
澳洲巴伐尼亚鳅（Bhavania australis）原生于印度南部西高止山脉。它是贴附急流石面的爬鳅，养护重点是稳定富氧的流水、成熟附着生物和合适的小型食物。
分布与栖息地
为印度西高止山脉特有种，记录来自喀拉拉、泰米尔纳德和卡纳塔克等邦。生活在浅、急、富氧的上游与小支流，急滩和水潭相间，底部多石砾及大卵石，水草通常不多。
饲养环境
底面积可参考 120 × 30 厘米。用砂砾及多种大小圆石提供觅食面，强过滤按需配合气石、造流，每小时循环可参考水体的 10–15 倍。较强光照支持附着生物，避免新沉木大量染水；附生植物、外露海绵可增加食物和遮蔽表面。只入成熟缸，定期部分换水，清洁时保留多数生物膜。
食性与喂食
同属会刮食生物膜及小型底栖无脊椎动物。部分下沉干粮可能接受，仍应定期供给水蚤、丰年虾、红虫等活冷冻饵，并让石面保留附着物。明显消瘦的个体需要持续、容易取得且少竞争的食物。
习性与混养
并不好斗，但适宜伙伴受流水和溶氧需求限制，相似爬鳅可能有轻微争执。建议六尾以上同养，单尾或小群时较不大胆。
补充说明
扁平头身和横向偶鳍帮助它贴住石块，活动常呈沿表面爬行或短距离跳移。国际贸易较少见，不能因外观像其他吸鳅就省去身份核对。

Overview
Native to the Western Ghats of southern India, Bhavania australis is a clinging stream loach. Mature grazing surfaces, oxygen-rich circulation, and suitable small foods are central to care. The epithet australis refers to its southern distribution.
Distribution & habitat
It is endemic to the Western Ghats, with records in Kerala, Tamil Nadu, and Karnataka. Shallow fast headwaters and tributaries contain riffles and pools over rocky beds, with aquatic plants generally sparse.
Aquarium setup
An aquarium footprint of 120 by 30 cm is the suggested reference. Build plentiful smooth rocky surfaces over sand or gravel. Strong filtration with supplementary aeration or circulation should support a turnover around 10–15 tank volumes per hour. Light encourages surface growth; avoid heavily staining new wood. Hardy plants and accessible sponge surfaces add cover and grazing. Use mature water and regular partial changes while retaining biofilm.
Diet & feeding
Genus-level accounts describe grazing biofilm and small bottom-associated invertebrates. Some sinking prepared foods may work, but regular live or frozen prey remain important. Maintain surface growth, and give emaciated fish a continuous accessible food supply without competitors.
Behaviour & compatibility
It is not aggressive, though similar loaches can have minor disputes. Environmental requirements limit companion choice. Six or more together are recommended because isolated fish and small groups are less confident.
Notes
A flattened head and body with horizontal paired fins support clinging, crawling, and short hops over rock. Similar appearance to other hillstream loaches does not remove the need to confirm identity.
