概述
拉迪氏沼银汉鱼（Marosatherina ladigesi）是体型较小、性情温和的群游鱼，雄鱼鳍形和色彩尤其醒目。清洁、偏碱且有一定硬度的水体是基础；它对水质骤变敏感，入缸时的缓慢适应比额外加盐更重要。
分布与栖息地
来自印度尼西亚苏拉威西岛，旧称西里伯斯。天然栖地为山麓和河口一带清澈、缓流的溪流。
饲养环境
参考至少 76 × 30 × 30 厘米。茂密种植配少量浮水遮光能帮助发色，但植物区之间要保留游动与雄鱼展示空间。每周部分换水保持清洁，换水和转缸都避免突然改变条件。
不耐酸性水，买入时应了解原缸水质，若差别较大就缓慢适应。可耐轻度咸淡水并不代表必须加盐，普通合适的硬碱淡水也能饲养。
食性与喂食
通常接受干饲料、冷冻饵和活饵，保持多样菜单有助健康和体色。繁殖调理时提供足够活饵与冷冻饵，观察雌鱼是否逐渐饱满、雄鱼是否积极展示。
习性与混养
适合与相近体型、偏好较硬水的温和鱼混养。至少六至八尾、最好更多，群体可减少惊慌，雄鱼也更容易展示；雌雄比例可每雄配两三雌。若采用轻咸淡水系统，伙伴同样必须适应该条件。
雌雄区分
雄鱼颜色更鲜明，第二背鳍和臀鳍长出明显延长鳍条。
繁殖
属于散卵型，繁殖缸可不铺底砂，用小型气动过滤，准备大量细叶植物、莫丝或尼龙拖把。亲鱼先在其他缸成群调理，再选状态好的成对鱼，稍微降温有时能促进产卵；水保持稍硬、偏碱。
一对鱼可连续数周每天分批产卵，卵以细丝附在材料上。成鱼会吃卵，应经常检查，将卵移到装有原繁殖缸水的孵化缸。约 5–10 天孵化，刚出壳鱼苗先喂草履虫级微小食物，一周左右再用丰年虾无节幼体。鱼苗常贴近水面，沉底食物不合适，早期育苗比诱产更需要细心。

Overview
A small, peaceful schooling fish, Marosatherina ladigesi is particularly striking when mature males display. Clean, alkaline water with moderate hardness supports care. Sensitivity to rapid chemical change makes gradual acclimation important; salt is not a basic requirement.
Distribution & habitat
It is native to Sulawesi, Indonesia, historically called Celebes. Clear, slow streams near foothills and estuarine areas form its habitat.
Aquarium setup
Use at least the suggested 76 by 30 by 30 cm, with dense planted sections, some floating shade, and open lanes for swimming and display. Weekly partial changes maintain cleanliness, but changes in conditions must be gradual.
Acidic water is unsuitable. Compare the seller’s water with the destination and acclimate slowly when they differ. Mild brackish tolerance does not make salt necessary in otherwise appropriate freshwater.
Diet & feeding
Dry, frozen, and live foods are usually accepted. Use variety to support condition and color, increasing suitable live and frozen offerings during breeder conditioning.
Behaviour & compatibility
Choose similarly sized, peaceful companions that favor harder water. A shoal of at least six to eight, preferably more, reduces skittishness and promotes male displays. Two or three females per male are suggested. Brackish arrangements require equally suitable tankmates.
Sexual dimorphism
Males are more colorful and develop conspicuous extensions of the second dorsal and anal fins.
Breeding
This egg-scatterer can breed in a bare-base aquarium with gentle air filtration and abundant fine plants or spawning mops. Condition adults separately, then select a well-conditioned pair. Slight cooling may encourage spawning in mildly hard, alkaline water.
Pairs may deposit daily batches for several weeks, attaching eggs by fine threads. Adults eat eggs, so transfer collected eggs into spawning-tank water in a separate nursery. Hatching takes about 5–10 days. Begin tiny fry on infusoria-sized food, introducing Artemia nauplii after roughly a week. Fry stay near the surface, making sinking food unsuitable.
