概述
撤拉波鱼（Rasbora sarawakensis）是婆罗洲的小型温和群游鱼，名称虽指向砂拉越，分布并不限于该州。贸易中的出现情况不明确，照料重点是缓流、遮荫和足够同伴。
分布与栖息地
见于马来西亚砂拉越及邻近印度尼西亚西加里曼丹，包括数个河流系统。多生活在岸边植被稠密的缓流林溪，林冠遮荫，底部厚淤泥中混有枝条和落叶；水较清，仅带浅茶色。
饲养环境
小群可从 60 × 38 × 30 厘米缸起步。可借鉴小型波鱼采用深色底砂、较多水草、浮水植物和沉木来柔化光线。过滤不需特别强，过急的水流可能让它吃力，留出安静活动区。
食性与喂食
可能主要摄食小型水生、陆生无脊椎动物。可尝试适口干粮，并每天搭配小份水蚤、红虫等活饵或冷冻饵料。
习性与混养
至少 8～10 条群养，减少紧张并鼓励雄鱼展示。适合温和且环境需求接近的伙伴，混养安排也应照顾小体型和缓流水域习性。
雌雄区分
成熟雌鱼预计腹部更圆，也可能略大，这些判断仍需结合实际个体观察。
繁殖
被描述为散卵且不护卵，但家养繁殖情况不确定。可尝试近缘小型波鱼的方法：另设弱光浅缸、隔卵底和成熟水，一两对调养后入缸，分次补较凉水；约两天后移走亲鱼，使用海绵过滤。属内常见约 18～48 小时孵化，平游再需一两天，只作参考。先备微型食物，待能吞咽时再转丰年虾幼体、微虫。

Overview
A small peaceful Bornean fish, Rasbora sarawakensis occurs beyond the Malaysian state reflected in its name. Aquarium availability is uncertain. A sheltered, gently circulating group setup fits its forest-stream setting.
Distribution & habitat
Its range includes Sarawak and neighboring West Kalimantan. Slow forest streams with dense bankside vegetation are typical. Shaded water is relatively clear but lightly tinted, above silty beds containing fallen leaves and branches.
Aquarium setup
A small group can be housed from 60 by 38 by 30 cm. Planting, a dark base and overhead shade are reasonable choices based on related small rasboras. Keep the filter flow gentle and retain sheltered swimming space; forceful current may be difficult for this fish.
Diet & feeding
Small invertebrates are the probable wild food. Suitable prepared feeds should be accepted, with regular live or frozen supplements.
Behaviour & compatibility
Keep eight to ten or more to encourage confidence and male displays. Choose peaceful companions with compatible size and environmental needs, including modest water movement.
Sexual dimorphism
Mature females are expected to be fuller-bellied and perhaps larger; these are provisional sexing clues.
Breeding
Captive breeding is uncertain, though the fish is described as an egg scatterer without care. A trial adapted from relatives can use a dim shallow tank, mature water and an egg barrier. Add conditioned pairs and cooler water in small increments, then remove adults after a couple of days. Use sponge filtration. Genus-level development times are only guidance; start fry on microscopic foods before progressing to larger prey.
