Nana Acropora is an Acropora with thin, straight branchlets of even thickness that radiate at regular intervals from a solid base. Colonies are often cream, blue or purple with purple branch tips, giving them a neat, finely detailed look. Adult size is poorly documented, but the colony grows by spreading its branchlets outward, which shows off its form in the tank. The branchlets are delicate and break easily, and the species is rated for advanced keepers. Reliable information on lifespan is limited, so it is best suited to hobbyists who are comfortable managing water quality, flow and lighting.

Nana Acropora key facts
- Care level
- Advanced
- Lifespan
- Little data available
- Size
- Up to about 20 cm (Reeflex)
- Temperature
- 24〜27℃
- Diet
- Mainly photosynthesis (zooxanthellae)
- Lighting
- SPS corals prefer moderate to high light, and Acropora need especially strong light (AlgaeBarn). Place it in the upper part of the tank.
- Flow & Placement
- In the wild it lives on reef flats with strong currents or waves (Corals of the World). Give strong, changing flow so detritus does not settle between the branchlets.
- Water Temperature & Quality
- 24-27°C, salinity 33-35 ppt (SG 1.023-1.025). It does not tolerate sudden swings in alkalinity, calcium or magnesium, so keep it only in a mature, stable tank.
- Diet & Feeding
- It gets most of its nutrition from zooxanthellae. Limit feeding to fine particulate food that does not foul the water.
- Health & Cautions
- The colony is delicate and branchlets snap easily (Corals of the World), so avoid touching it when moving or cleaning. Not a beginner coral (Reeflex).
About Nana Acropora
Nana Acropora: thin, straight branchlets radiate from a solid base. Advanced-level care, and what to know before buying.
7 things to know before welcoming a Nana Acropora
1Advanced-level care
Care difficulty is rated for advanced keepers, so it suits those already comfortable managing water quality, flow and lighting. If you are new to corals, it is reassuring to first stabilize a tank with hardier species before considering this one.
2Fragile branchlets
The thin, evenly sized branchlets can snap under force. When moving or cleaning, avoid touching the tips and support the colony by its base. Take care to prevent knocks and drops during handling.
3Light and flow
Acropora tend to do well with ample light and flow that reaches between the branches. Because the branchlets radiate outward, place the colony where water does not stagnate. Moving it abruptly into strong light can cause paling or damage, so increase exposure gradually.
4Stable water quality
It does best in a stable tank where temperature, salinity and nutrients change little. Test regularly and adjust in small steps rather than making large swings. A well-established tank is generally a safer home than a newly set-up one.
5How color appears
Colonies are often cream, blue or purple with purple branch tips. Appearance can shift with lighting color and tank conditions. Check the photos on each listing, including how they were taken.
6Room to spread
The branchlets extend outward in all directions, so leave open space around the colony. Adult size is poorly documented, so allow generous room for the branches to spread. Corals that touch their neighbors can damage each other, so keep some distance.
7Acclimating on arrival
On arrival, float the bag to match temperature and acclimate slowly. Acropora can carry pests, so if possible, check the colony in a separate container before adding it to the main tank. Also look for any change in tip color or tissue condition.
Frequently asked questions about Nana Acropora
- Q.Can beginners keep it?
- A.Its care level is rated for advanced keepers. We recommend considering it once you can maintain a coral tank steadily and are comfortable managing water quality, flow and lighting.
- Q.How large does it grow?
- A.Its size is poorly documented, so no clear figure can be given. It grows by spreading its branchlets outward, and because they are thin and break easily, plan a layout with plenty of space around the colony.
- Q.How long does it live?
- A.Reliable information on lifespan is limited, so a clear figure is not known. To keep it for a long time, stabilize water quality, flow and lighting, and avoid sudden changes in its environment.
- Q.Does its color change?
- A.The base color is often cream, blue or purple, and many colonies have purple branch tips. Its appearance can vary with lighting color and tank conditions, so consider how each listing photo was taken.
- Q.Is it listed under CITES?
- A.Yes, it is listed in CITES Appendix II. Please also check the details written on each listing page.
