概述
Batasio tigrinus 是泰国西部的小型溪流鲿科鱼，适合有水流、溶氧充足的专门环境。它竞争力不强，不能因为体形不大就与强势鱼挤在普通混养缸中。
分布与栖息地
似乎为桂诺河流域特有，模式产地位于北碧府桑卡拉武里与通帕蓬之间。桂诺河与桂艾河汇合后属于美功河水系。其属的典型栖地是小河上游浅急水域，底部有砂砾、石块与裸岩，岸边植物及局部落叶常见。
饲养环境
用不同粒径的石块和砾石，加水磨大石、沉木枝根营造溪流布局，可种强健附生植物。保持水质洁净，不能任有机废物累积；过滤和造流共同维持溶氧与水流，每周换水 30–50%。
食性与喂食
天然食物可能为小型甲壳类、蠕虫、昆虫幼体等。可投喂红虫、水蚯蚓、丰年虾及孑孓等小型活饵或冷冻饵。部分个体会吃沉底干粮，但新进口野生鱼最初可能不接受，不应只靠一种饵料试运气。
习性与混养
避开明显更大、凶猛或抢食强的伙伴。体形适当的温和群居鲤科鱼，以及习性适合的溪流鲶鱼、吸鳅，可以考虑；其他鳅类要先确认领地性和成体大小。
繁殖
同属其他鱼已有繁殖成功经验，可在亲鱼状态良好时尝试以偏凉水作较大换水。那些案例的卵随机散落、约两天孵化，但这些并非本种已经确认的产卵及孵化记录。

Overview
From western Thailand, Batasio tigrinus is a small stream catfish for a carefully maintained, oxygen-rich flowing aquarium. Its modest competitive ability makes companion choice as important as water conditions.
Distribution & habitat
The species appears confined to the Khwae Noi basin, with its type locality between Sangkhla Buri and Thong Pha Phum in Kanchanaburi. This river joins the Khwae Yai within the Mae Klong drainage. Members of the genus occupy shallow upland runs over sand, gravel, and rock, often bordered by vegetation and leaf deposits.
Aquarium setup
Combine mixed gravel and stones with rounded boulders and branching wood to create a stream layout. Hardy plants attached to decor are suitable. Keep organic waste under control, provide ample dissolved oxygen and circulation, and replace 30–50% of the water weekly.
Diet & feeding
Its probable prey consists of small crustaceans, worms, and insect larvae. Offer appropriately small live or frozen bloodworms, Tubifex, Artemia, and mosquito larvae. Some fish accept sinking dry preparations, but freshly imported wild individuals may initially refuse them.
Behaviour & compatibility
Choose companions that will not dominate this relatively uncompetitive catfish. Peaceful shoaling cyprinids, compatible stream catfish, and suitable hillstream loaches are possibilities. Check the adult size and aggression of other loaches before combining them.
Breeding
Breeding in other members of the genus suggests trying large cooler-water changes when adults are in suitable condition. Eggs in those cases were scattered and hatched in about two days. These are comparative observations, not confirmed spawning or incubation results for this species.
