概述
Batasio travancoria 来自印度西南部，体侧暗纵带和鳃盖后不甚清晰的暗斑可辅助识别。它属于需要清洁流水的小型鲿科鱼，饲养重点是溪流式环境和避免强势邻居。
分布与栖息地
为印度喀拉拉邦南部特有，已知涉及潘巴河、奇塔尔河及卡拉达河流域。同属鱼典型生境是溪流源头、小河上游的浅急水段，砂石、大岩块与裸岩交错，岸边植物及局部水下落叶较常见。
饲养环境
以砾石、不同大小石块和水磨大石模拟溪流，沉木枝根及强健附生水草提供遮蔽。它不耐有机污染积累，要有有效过滤、充分水流与高溶氧，每周规律换水 30–50%。
食性与喂食
可能在野外摄食小型甲壳类、蠕虫及昆虫幼体。缸中主要喂小型活饵或冷冻饵，如红虫、水蚯蚓、丰年虾和孑孓。沉底成品饲料也有使用成功的情况，但新进口野生个体可能先拒绝。
习性与混养
不宜与体形悬殊或好斗的鱼同养。可选温和、体形合适的群居鲤科鱼及相容的小型溪流鲶鱼，部分吸鳅也可考虑。其他鳅类需具体评估，领地性强或长得过大的种类不合适。
繁殖
其他同属鱼的繁殖案例可作尝试参考：亲鱼状态合适时，以偏凉水作一次或多次较大换水，可能诱发繁殖。随机散卵和约两天孵化属于这些同属案例，不能视作本种已证实结果。

Overview
A dark flank stripe and a diffuse spot behind the gill cover help recognize Batasio travancoria. This southwestern Indian catfish needs clean flowing water and companions that will not overwhelm it.
Distribution & habitat
Endemic to southern Kerala, it is recorded from the Pamba, Chittar, and Kallada drainages. Typical habitats of the genus are shallow headwaters with rapid runs over sand, gravel, and boulders. Bankside vegetation and patches of submerged leaves are common features.
Aquarium setup
Use varied gravel and stones with worn boulders, roots, and sturdy attached plants. This species does not tolerate organic waste buildup well. Effective filtration and circulation should keep oxygen high, backed by weekly changes of 30–50%.
Diet & feeding
Small crustaceans, worms, and insect larvae are likely natural foods. Feed mostly small live or frozen bloodworms, Tubifex, Artemia, or mosquito larvae. Prepared sinking foods have been used successfully, although new wild imports may be reluctant to accept them.
Behaviour & compatibility
Avoid substantially larger or aggressive fishes. Peaceful shoaling cyprinids of comparable size and compatible small stream catfish are candidates, as are suitable hillstream loaches. Other loaches require individual assessment because some become territorial or too large.
Breeding
Related-species experience offers an experimental starting point: one or more large changes with cooler water may stimulate adults in breeding condition. Scattered eggs and approximately two-day incubation were observed in those relatives, not established here as species-specific results.
