關於指狀軸孔珊瑚

A digitate Acropora coral with colonies up to a meter wide and blue-tinged branch tips. Smaller and finer-branched than A. humilis, best suited to experienced reef keepers.

迎接指狀軸孔珊瑚前需要了解的7件事

1. 1Advanced-Level Care Difficulty

   Acropora digitifera is generally considered an advanced-level coral to keep, since it's sensitive to changes in lighting, water flow, and water quality. It's a good idea to gain experience with hardier corals first before adding this species to your tank.

2. 2Digitate, Finger-Like Branches

   True to its name, this coral grows slender, finger-like branches radiating outward to form its colony. Each branch tip carries an elongated, tube-shaped axial corallite, and the tips often take on a blue tint that's one of its most appealing features.

3. 3Telling It Apart from A. Humilis

   It's easy to confuse with the similar-looking Acropora humilis, but A. digitifera stays smaller overall and has finer, more tightly packed digitate lobes. Checking the branch structure closely, not just the label, helps confirm you have the right coral.

4. 4Colonies Can Reach 1m Across

   A mature colony can grow to about a meter across, making it a striking centerpiece in a large reef tank. Plan ahead for its eventual size by giving it plenty of tank space and room to spread in your layout.

5. 5Managing Flow and Lighting

   Steady water flow around and between the branches supports healthy growth throughout the colony. Insufficient lighting can slow branch extension and dull its coloration, so lighting intensity and placement need ongoing attention.

6. 6Keeping Water Quality Stable

   Like other Acropora species, A. digitifera is sensitive to sudden shifts in water chemistry. Regularly testing parameters such as calcium and alkalinity, and keeping them stable, is essential to keeping it healthy.

7. 7Handle Branches with Care

   Because the colony is made up of thin, delicate branches, applying too much force during aquascaping or maintenance can snap them. When trimming or repositioning the coral, support the base of the branch and work slowly and carefully.

A.Acropora digitifera is generally considered an advanced-level coral to keep, since it's sensitive to changes in lighting, water flow, and water quality. It's a good idea to gain experience with hardier corals first before adding this species to your tank.

Q.How can I tell it apart from Acropora humilis?

A.A. digitifera looks similar to A. humilis but stays smaller overall, with finer, more tightly packed digitate lobes. Comparing branch thickness and how finely the lobes are divided is the easiest way to distinguish the two.

Q.How large can this coral eventually grow?

A.A mature colony of A. digitifera can reach up to about a meter across. Since it can grow quite large in a tank, it's worth planning your aquascape layout with its future size in mind.

Q.Why do the branch tips often turn blue?

A.Blue-tinged branch tips are one of the notable features of this coral. How strongly the color develops varies between individual colonies and depends on tank conditions such as lighting and water quality.

Q.Does CITES apply to this coral?

A.Some coral species are subject to CITES, but Acropora digitifera is not one of them. CITES is the international treaty regulating trade in species considered at risk of extinction.
