硬棘軟珊瑚屬（Scleronephthya）

硬棘軟珊瑚屬（Scleronephthya）的基本資料

飼養難度

適合高級者

適宜溫度

24〜26℃

飲食

不具褐蟲藻的濾食性。需要持續供給植物浮游生物等微細餌料。

光線・照明

因不具褐蟲藻，光線非必需。自然環境中亦附著於凸緣下方或洞穴天花板等弱光場所。強光照下易附著藻類而衰退。

水流・配置

生活在潮通良好的區域，需供應強度較強的不規則水流。配置須確保懸浮物持續到達枝條。倒吊於凸緣下方最接近自然環境。

水溫・水質

水溫24〜26℃、比重1.023〜1.025（鹽度33〜35ppt）、pH 8.1〜8.4、KH 8〜12。投餵量大易導致營養鹽升高，需加強換水與物理過濾。

餌料・投餵

飼養成敗取決於投餵。AlgaeBarn針對非光合作用水族箱建議提供大量粒徑多樣的餌料，並推薦包含活的植物浮游生物與細菌浮游生物的組合。每日多次投餵或自動投餵裝置為現實做法。

注意事項

飼養難度非常高，長期飼養成功案例稀少。投餵不足會導致數週至數月內逐漸萎縮。因為軟珊瑚不形成骨骼，不在CITES管制名單內。

關於硬棘軟珊瑚屬（Scleronephthya）

A guide to Scleronephthya, a non-photosynthetic soft coral in red, orange, and white. This challenging species needs constant fine-particle feeding and suits experienced keepers.

迎接硬棘軟珊瑚屬（Scleronephthya）前需要了解的7件事

1. 1A Non-Photosynthetic Species

   Scleronephthya lacks zooxanthellae and does not photosynthesize. It relies on feeding rather than lighting for nutrition, which makes its care approach different from typical photosynthetic corals.

2. 2Requires Constant Fine Feeding

   Without zooxanthellae, it depends on frequent feedings of fine particulate food such as phytoplankton. Gaps in feeding can gradually weaken the coral, so establishing a reliable feeding routine is essential.

3. 3Cluster-Like Polyp Bundles

   Its main appeal is the dense, cluster-like bundles of polyps that open at the branch tips. Compared to related Dendronephthya species, its branches are shorter and more compact, giving it a tidy overall shape.

4. 4水流和水質的管理

   由於頻繁投餵，水質容易惡化。需要通過穩定的水流讓食物遍佈全體，同時進行細緻的水質管理，打造能夠維持穩定環境的條件。

5. 5Vivid, Varied Coloration

   Its standout feature is vivid coloration in shades of red, orange, and white. Since coloration varies between individuals, choosing one with your favorite hue is part of the enjoyment.

6. 6A Species for Experienced Keepers

   This coral is rated as suited to experienced keepers. Its demanding feeding routine and environmental requirements make it best attempted by those already comfortable with coral care.

7. 7迎接前的準備

   購買前，應確認是否能穩定地提供和投餵微細飼料。由於每次投餵時水質容易波動，建議同時做好水質監測的準備會更加放心。

硬棘軟珊瑚屬（Scleronephthya）的常見問題

Q.Can beginners keep Scleronephthya?

A.It is considered a challenging species suited to experienced keepers. Since it lacks zooxanthellae and cannot photosynthesize, it needs frequent feedings of fine food, which requires practiced feeding management.

Q.Does it need strong lighting?

A.Since Scleronephthya is non-photosynthetic and lacks zooxanthellae, it doesn't rely on strong light for nutrition. If lighting is used for tankmates, it's best positioned away from very intense direct light.

Q.What kind of food does it need?

A.It requires frequent feedings of fine particulate food such as phytoplankton to sustain a near-constant food supply. Long gaps between feedings can cause it to weaken.

Q.How is it different from Dendronephthya species?

A.Scleronephthya is closely related to Dendronephthya but forms shorter, more compact branches, with polyps opening in dense cluster-like bundles at the branch tips, giving it a tidier overall shape.

Q.Are there any international trade regulations?

A.Scleronephthya is not subject to CITES.
