Acropora Nasuta is a stony coral known for its tapering branches that spread outward and flatten into a table-like colony as it matures. Neat vertical rows of radial corallites run along each branch, creating a distinctive, orderly texture. Its base coloration ranges from creamy white to pale brown, and the growing branch tips can take on a bluish tint, adding to its visual appeal. Branches reach up to about 12mm in diameter, giving mature colonies real presence in a reef tank. Because it is sensitive to shifts in water quality and lighting, this species is best suited to experienced reefkeepers rather than beginners.

Acropora Nasuta key facts
- Care level
- Advanced
- Size
- Branches up to 12 mm wide
- 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
- Because the colony forms a flat-topped clump, place it where light and flow reach the whole upper surface evenly, with enough flow to keep detritus out of the branches.
- 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
- Polyps extend at night to feed. As a shallow-water species it is susceptible to bleaching and coral disease, and crown-of-thorns starfish preferentially prey on Acropora. Listed on CITES Appendix II.
About Acropora Nasuta
Acropora Nasuta is a stony coral with tapering, flattening branches and neat corallite rows, with tips sometimes tinged blue. Branches reach up to 12mm; best suited to experienced keepers.
7 things to know before welcoming a Acropora Nasuta
1Advanced-Level Care
Acropora Nasuta is sensitive to fluctuations in water quality and lighting, so keeping it healthy requires experience maintaining a stable reef tank. It's best introduced after you've had success with other Acropora species first.
2A Flattening Growth Form
The tapering branches spread outward and often flatten into a table-like shape as the colony matures. Give it enough open space in the tank to accommodate this spreading growth pattern.
3Neatly Arranged Corallites
The radial corallites form tidy vertical rows along each branch, creating the coral's signature orderly texture. This pattern also serves as a useful visual marker when checking on the colony's condition.
4Cream-White to Pale Brown Coloration
Base coloration ranges from creamy white to pale brown, with branch tips sometimes taking on a bluish hue. How the color develops can vary depending on lighting and water conditions.
5Needs Strong Light and Flow
Like most Acropora, healthy growth depends on adequate lighting and steady water flow. Choose a placement in the tank after checking the light intensity and flow reaching that spot.
6Branches Reach Up to 12mm
Branch diameter tops out at around 12mm, a fairly typical size range among Acropora species. The colony as a whole becomes more prominent in the tank as it grows.
7Confirm Tank Stability Before Bringing One Home
Before introducing this coral, make sure parameters such as calcium and alkalinity are stable in your tank. Keep a close eye on it while it acclimates to its new environment.
Frequently asked questions about Acropora Nasuta
- Q.Can beginners keep Acropora Nasuta?
- A.It's considered an advanced-level coral that's sensitive to changes in water quality and lighting. It's best to gain experience with other Acropora before keeping this species.
- Q.How large does it grow?
- A.Branches can reach up to about 12mm in diameter. The tapering branches spread out and often flatten into a table-like shape as the colony matures.
- Q.How does its coloration change?
- A.The base color ranges from creamy white to pale brown. Branch tips can take on a bluish tint, and the overall appearance can shift depending on lighting and water conditions.
- Q.What should I consider for placement?
- A.Since it spreads out flat as it grows, allow enough surrounding space in the tank. It's also important to choose a spot with adequate lighting and water flow.
- Q.Is this coral subject to any regulations?
- A.Acropora Nasuta is listed in CITES Appendix II. International trade requires a permit from the exporting country, but as far as CITES is concerned, no registration is needed to buy or sell individuals already legally in Japan.
