扁棘杯珊瑚

扁棘杯珊瑚的基本資料

飼養難度

適合中級者

壽命

資料較少

體型

野生群體直徑常超過1米（《世界珊瑚志》）

適宜溫度

24〜27℃

飲食

光合作用（褐蟲藻）+ 投餌

光照强度

LPS珊瑚喜弱至中等光照（AlgaeBarn）。引入初期置於較低位置，邊觀察顏色和組織緊張度邊移至更明亮處。

水流與放置

阿肯珊瑚類喜弱至中等水流（AlgaeBarn）。將肉質組織平穩安置在岩石上，避免摩擦。

水溫和水質

水溫24至27℃，鹽度33至35ppt（比重1.023至1.025）。因需形成骨骼，需維持鈣和KH穩定。

饵料和投饵

依賴光合作用，觸手展開時在口盤投入細小冷凍餌料或珊瑚專用食物。

健康與注意事項

長期飼養報告較少的物種（Reeflex）。購買時確認杯的形狀，多角形密集排列則為本種，圓形分離則可能為小棘杯珊瑚。

關於扁棘杯珊瑚

Hemprich's Acan Coral has mottled brown and green corallites packed into polygons. See its intermediate care level and what to know before you buy.

迎接扁棘杯珊瑚前需要了解的7件事

1. 1Telling It Apart

   Neighboring corallites that share walls and pack together into polygons are the hallmark of Hemprich's Acan Coral. A look-alike acan with separated, fleshier corallites can be told apart by this arrangement. Check how the corallites are set in the listing photos, and ask the seller if you are unsure.

2. 2Difficulty and Lifespan

   Care difficulty is rated intermediate, so it suits keepers who are comfortable running a marine tank and holding water quality steady. Documentation on lifespan is limited, and no clear figure is known.

3. 3Room to Grow

   Wild colonies often exceed 1 m in diameter. A tank colony will not necessarily reach that size, but because it spreads as an encrusting sheet or mass, leave room around it when choosing a spot.

4. 4Space From Neighbors

   Corals can harm neighboring colonies through contact and tentacles. Allow for the colony spreading and keep a generous gap from other corals. If growth brings it close to a neighbor, reconsider its placement.

5. 5Easing Into Light and Flow

   Avoid placing it straight into intense light or strong flow, and start in a calmer spot instead. Watch how the corallites open and adjust its position bit by bit.

6. 6Acclimating on Arrival

   On arrival, acclimate it slowly so the difference between the shipping water and your tank water is bridged gradually. When moving it, handle the skeleton or base rather than the tissue.

7. 7Daily Observation

   The brown and green coloration and how the corallites swell are clues to its condition. If it stays deflated or its colors change for an extended period, review water quality, lighting and flow. If you plan to feed it, ask the seller how they do it.

扁棘杯珊瑚的常見問題

Q.Can a beginner keep it?

A.It is rated for intermediate keepers. Getting comfortable with marine water-quality management first makes it easier to respond calmly to changes in its condition.

Q.How is it different from Hime-oo-toge-kikumeishi?

A.In Hemprich's Acan Coral, neighboring corallites share walls and pack tightly into polygons. Hime-oo-toge-kikumeishi has corallites that sit apart and look fleshier.

Q.How large does it grow?

A.Wild colonies often exceed 1 m in diameter. How large it gets in a tank depends on conditions, so it is wise to plan a placement with room to spread.

Q.How long does it live?

A.Documentation on lifespan is limited, so no clear figure is known. To keep it for the long term, hold water quality, lighting and flow steady and watch for daily changes.

Q.Is it listed under CITES?

A.Yes, it is listed in CITES Appendix II. Read the listing page as well, and ask the seller if anything is unclear.
