簡介：肚兜萍 Salvinia cucullata 是一種小型浮水蕨類植物，常見於熱帶和亞熱帶地區的靜水環境中。其特徵是綠色的浮葉，形狀像肚兜，通常漂浮在水面上，有助於改善水質並為水生生物提供棲息地。

適合場景：肚兜萍非常適合用於水族箱、水草缸或濕生生態缸中。由於其浮水特性，不適合土壤種植，但可以有效地改善水質和增添水景的層次感。

養護要點：

光照：需要充足的光照以促進健康生長。建議使用強光或全光譜燈，光照不足可能會影響植物的生長和浮葉的健康。
水溫：最適水溫範圍為22°C至30°C。此植物對水溫變化有一定的適應性，但長期的極端水溫可能會影響其健康。
水質：喜歡清澈的軟水，pH值範圍為6.0至7.5。保持水質清潔對於植物的生長非常重要，可以定期更換水以保持水質良好。
施肥：通常不需要施肥，但如果水質較差，可以添加少量水生植物專用肥料。避免過量施肥，以免導致藻類生長。
修剪：肚兜萍的生長速度較快，可以定期移除過多的浮葉，以保持水族箱或水草缸的美觀和健康。
病蟲害：此植物對病蟲害的抵抗力較強，但仍需定期檢查是否有藻類或其他水生生物的侵擾。保持良好的水質和適當的環境有助於預防問題。

小提示：肚兜萍的浮葉可以幫助控制水中的藻類生長，保持水體清潔。安置時，確保它有足夠的空間來漂浮，以便充分發揮其水質改善作用。

Salvinia cucullata, commonly known as Hooded Salvinia or Asian Watermoss, is a distinctive floating fern native to Southeast Asia. It is easily recognized by its unique cupped or “hooded” floating leaves, which form compact rosettes that trap air and keep the plant buoyant. The leaf surface is covered with fine, water-repellent hairs, allowing the plant to stay dry and float stably even in gentle water movement.

In aquariums and aquascaping, Salvinia cucullata is valued for its ability to create a soft, natural canopy on the water surface. By diffusing bright light and providing shaded areas, it helps protect fish, shrimp, and light-sensitive plants. Its surface coverage also helps reduce algae growth by limiting excess light penetration.

This species grows quickly under warm temperatures, moderate lighting, and calm water conditions. Although fast-spreading, it is easy to control by simply removing excess clusters. Its trailing roots beneath the surface offer excellent hiding spots for fry and shrimp, enhancing both aesthetics and habitat quality.

Beyond its beauty, Hooded Salvinia contributes to water stability by absorbing excess nutrients, which helps maintain healthier aquarium conditions. Attractive, useful, and beginner-friendly, Salvinia cucullata is an excellent addition to natural-style tanks and shrimp aquariums.
