概述
凯蒂柯氏鳅（Kottelatlimia katik）成年也极微小，却并不适合随便养在极小容器。它保留较长鳍和鼻须等幼态特征，喂食尤其要注意颗粒细度，大块食物无法吞入。
分布与栖息地
马来半岛柔佛的模式材料产地为推测，另有印度尼西亚苏门答腊巴塘哈里河记录。砂拉越相似鱼身份未确定。常见于林下缓流小溪及黑水泥炭沼泽，水软、缓冲能力低，常在落叶堆中活动。
饲养环境
底面积至少参考 45 × 30 厘米。提供软沙供埋身，粗砾会影响取食并可能磨伤；枝根、圆石间保留开阔沙地，弱光、落叶和附生植物增加遮蔽。水质要洁净稳定，只放入成熟缸。
食性与喂食
通过筛砂捕捉微小昆虫幼虫、甲壳类等。用极细下沉粮、丰年虾无节幼体、小水蚤及切碎蠕虫组成食谱，避免无法吞咽的大块饵。
习性与混养
体质纤弱，不与明显较大或争食强的鱼搭配；小型温和群游鱼、适合软酸水的小型迷鳃鱼可考虑。其他底层鳅须核对体形、性格及水质要求。可参照同属至少四尾的群养建议，卵或鱼苗仍可能被吃。
雌雄区分
成熟雄鱼第一条分枝胸鳍鳍条增粗，内缘有六至七枚细锯齿；雌鱼通常略大、较厚实。

Overview
Minute even as an adult, Kottelatlimia katik should not be assigned an arbitrarily tiny container. Long fins and nasal barbels reflect retained juvenile features. Food size is especially important: particles suitable for larger loaches may simply be impossible to swallow.
Distribution & habitat
The presumed origin of the type material is Johor in Peninsular Malaysia, with additional records from Sumatra’s Batang Hari drainage. Similar Sarawak fish remain unidentified. Shaded slow forest streams and peat-swamp waters have very low mineral content and weak buffering, with fish often using leaf piles.
Aquarium setup
Provide at least a 45 by 30 cm base with soft sand for burial. Coarse gravel can disrupt feeding or cause injury. Leave open sand between branches and smooth rocks, using subdued lighting, leaves, and attached plants for cover. Introduce it only to an established aquarium with consistently clean water.
Diet & feeding
It sifts substrate for tiny invertebrates. Supply very fine sinking food, nauplii, suitably small water fleas, and finely chopped worms. Oversized items provide little value when the fish cannot ingest them.
Behaviour & compatibility
Avoid much larger or competitive fishes. Tiny peaceful schooling species or compatible small blackwater anabantoids are possible companions. Other loaches need careful checks of adult size, behavior, and water needs. Genus-level guidance favors at least four, while eggs and fry may still be vulnerable.
Sexual dimorphism
Mature males have an enlarged first branched pectoral ray with six to seven fine serrations along its inner edge. Females are usually slightly larger and heavier-bodied.
