概述
新平鳍鳅（Neohomaloptera johorensis）体形小，体色带橙红至褐色，原生于酸性黑水沼泽。虽然外形容易使人联想到急流爬鳅，它的布缸重点却是柔和水流、软酸水、遮蔽和成熟食物表面。
分布与栖息地
已知来自马来半岛柔佛、雪兰莪及霹雳等地，印度尼西亚西加里曼丹卡普阿斯流域也有鉴定为本种的记录。苏门答腊巴塘哈里流域的相似鱼体色和鼻须不同，不能直接算作同种。栖地多为泥炭沼泽林中的静缓黑水，植被密、树根和落叶丰富，水中矿物质很少。
饲养环境
底面积可参考 45 × 30 厘米。软砂、根枝、落叶和耐受植物提供隐蔽，小型水泵、过滤出水或气石维持溶氧即可，无需湍流。只入水质稳定的成熟缸，避免污染；进水口要防小鱼被吸入，缸盖也须贴合。
食性与喂食
天然会刮食生物膜、小型甲壳类和昆虫幼虫等无脊椎动物。提供适口水蚤、丰年虾、微虫等，部分下沉干粮可能接受，同时让石面保有附着生物。瘦弱鱼需要少竞争、持续且容易取得的食物。
习性与混养
性情温和，适合能共用黑水条件的细小温和鱼，体形和抢食能力都要相称。四尾以上一起饲养较合适；对其他鱼的卵和极小鱼苗仍可能构成风险。
雌雄区分
成熟雌鱼预计略大、更丰满，体形只宜作初步线索。

Overview
A tiny orange-red to brown loach, Neohomaloptera johorensis belongs in a soft, acidic blackwater setting. Its appearance should not lead to a torrent-style aquarium: gentle circulation, cover, and established feeding surfaces are more appropriate.
Distribution & habitat
Records include several parts of Peninsular Malaysia and specimens identified from the Kapuas drainage in western Borneo. Similar fish from the Batang Hari basin differ in color and nasal barbels and should not automatically be included. Peat-swamp habitats contain still blackwater, dense vegetation, submerged roots, and decaying leaves, with very low mineral content.
Aquarium setup
Use a suggested footprint of at least 45 by 30 cm with soft sand, wood, leaves, and suitable plants. A filter outlet, small pump, or air stone can supply oxygenation without creating turbulent conditions. Mature stable water is essential. Protect intakes against the small fish and fit the cover securely.
Diet & feeding
Natural feeding includes biofilm and tiny invertebrates such as crustaceans and insect larvae. Offer appropriately small live or frozen prey and established grazing surfaces; sinking prepared foods may also be accepted. Thin individuals need sustained easy access to food without competition.
Behaviour & compatibility
Choose very small, peaceful companions suited to blackwater and comparable feeding competition. A group of four or more is recommended. Peaceful behavior toward adults does not exclude a possible risk to eggs or very small fry.
Sexual dimorphism
Mature females are expected to be slightly larger and fuller-bodied, so body shape is a tentative clue.
