黑太阳珊瑚

关于黑太阳珊瑚

Black Sun Coral is a non-photosynthetic stony coral whose polyps extend at night to catch plankton. An advanced-level species that grows about 4 cm per year.

迎接黑太阳珊瑚前需要了解的7件事

1. 1Feeding Is Essential

   Because it lacks zooxanthellae, this coral can't photosynthesize for energy and depends entirely on direct feeding of animal plankton. Skipping feedings over time leads to gradual decline, so consistent care is essential.

2. 2No Need for Strong Light

   As a non-photosynthetic coral, it doesn't need the intense lighting that reef-building corals require. It actually does better in a calmer spot away from direct, strong light.

3. 3Feed After Lights-Out

   The polyps extend about 3 cm at night to catch plankton, staying withdrawn for most of the day. Feeding is best timed for after the lights go out, when the polyps are actually open.

4. 4Advanced-Level Care

   Due to the demands of frequent feeding and water-quality upkeep, this coral is considered suitable for advanced keepers. It's best approached after gaining experience with easier corals first.

5. 5Keep Flow Moderate

   Provide gentle, moderate water flow so the polyps can extend fully. Flow that's too strong can interfere with feeding and keep the polyps closed.

6. 6Watch Water Quality

   Because it's fed a lot of meaty food, water quality can deteriorate more quickly than with photosynthetic corals. Regular nutrient export, such as with a protein skimmer, helps keep conditions stable.

7. 7Plan for Growth Space

   Growth is fast for a non-reef-building coral, at roughly 4 cm per year. Colony height can reach up to 1 m for Philippine specimens or up to 44 cm for Red Sea specimens, so plan its placement with future size in mind.

黑太阳珊瑚的常见问题

Q.Can beginners keep this coral?

A.This is considered an advanced-level species. It requires a solid understanding of feeding routines and water-quality management, so it's best kept by hobbyists with some coral-keeping experience already.

Q.It looks dull during the day, is that a problem?

A.No, that's normal. The polyps extend only at night to feed, so during the day you're seeing just the skeleton, which naturally appears dark green to black.

Q.Does it need strong lighting?

A.No. As a non-photosynthetic coral without zooxanthellae, it doesn't rely on light for energy, so intense lighting isn't required the way it is for reef-building corals.

Q.How large does it grow?

A.Size varies by origin: Philippine colonies can reach up to about 1 m in height, while Red Sea colonies reach up to about 44 cm. Growth is roughly 4 cm per year.

Q.What should I feed it?

A.Direct feeding of animal plankton is needed while the polyps are extended at night. Since it doesn't feed during the day, timing your feedings to the evening is important.
