Acropora Hyacinthus (Table Acropora)

The Hyacinthus Table Acropora is a striking coral known for its lattice-like network of thin branches that spreads out into a broad, table-shaped colony. Its branch tips curve sharply, ringed with small cup-shaped structures that give the colony a delicate, intricate texture. Growth is fast, with the colony diameter expanding roughly 3 to 10 cm per year, making it rewarding for aquarists who enjoy watching their layout evolve. That said, this coral is considered suitable for experienced keepers, as it can be sensitive to shifts in water quality and lighting. It's a great choice for hobbyists ready to give a coral close, attentive care.

Acropora Hyacinthus (Table Acropora) key facts

Care level
Advanced
Size
Colonies can exceed 1 m across
Temperature
24〜27℃
Diet
Mainly nutrition from symbiotic zooxanthellae, supplemented with powdered or liquid coral foods and phytoplankton.
Lighting
Requires strong light. AlgaeBarn cites successful Acropora keeping at PAR 800 or more. Start newly added colonies under reduced light and raise it over several weeks.
Flow & Placement
Allow for the footprint the table will eventually cast: corals beneath it are easily shaded. Make sure strong flow also reaches the underside of the plate.
Water Temperature & Quality
Water 22-26C, specific gravity 1.023-1.025, KH 8-12, calcium 380-440 ppm, magnesium 1300-1400 ppm. Sudden swings in alkalinity are the most common cause of tissue loss.
Feeding
Most of its nutrition comes from photosynthesis by its zooxanthellae. Powdered or liquid coral foods and phytoplankton can be offered as a supplement, but stable light and water chemistry matter more than feeding.
Notes
It grows fast, adding 3-10 cm of diameter a year, so plan on periodic fragging to manage colony size. Tabular Acropora are easily confused with one another. Listed on CITES Appendix II.

About Acropora Hyacinthus (Table Acropora)

Hyacinthus Table Acropora is a classic table coral with lattice-like branching. Fast-growing and best suited to experienced reef keepers.

7 things to know before welcoming a Acropora Hyacinthus (Table Acropora)

  1. 1Advanced Care Level

    Hyacinthus Table Acropora is sensitive to fluctuations in water quality, lighting, and flow, requiring a consistently stable environment. It's best suited to keepers with prior Acropora experience or a solid understanding of reef tank management.

  2. 2Broad, Table-Shaped Growth

    Colonies can reach over 1 meter in diameter, growing at a rate of about 3 to 10 cm per year. Be sure to allocate ample open space around the placement site to accommodate this spread.

  3. 3Requires Strong Light and Flow

    Strong lighting and vigorous water flow are essential to maintaining the coral's characteristic lattice-like branch structure. Position it high in the tank where both light and flow reach consistently.

  4. 4Distinctive Cup-Shaped Tips

    The branch tips curve sharply, surrounded by small cup-shaped structures around a larger central one. Observing this intricate detail is one of the pleasures of keeping this coral.

  5. 5Stable Water Parameters

    Maintaining calcium, alkalinity, and magnesium within stable ranges is key to healthy growth. Make regular water testing part of your routine.

  6. 6Pre-Purchase Tank Readiness

    Before bringing one home, confirm that your lighting, flow, and water quality equipment can meet this coral's demands. Introducing it into an unprepared setup can lead to poor health.

  7. 7Spacing from Other Corals

    Because of its fast growth and wide spread, it's best placed with enough distance from neighboring corals to avoid future contact as the colony expands.
