Sun Hard Coral (Tubastraea sp.)

(Also known as Sun Coral, Sunburst Coral, or Orange Cup Coral)

Overview

The Sun Hard Coral (Tubastraea sp.) is a brilliantly coloured large-polyp stony (LPS) coral, renowned for its radiant yellow-orange polyps and sunburst appearance. Each tubular polyp opens into a delicate, flower-like structure, creating a vibrant display reminiscent of a blooming bouquet. Unlike most corals, Tubastraea is non-photosynthetic, meaning it does not rely on light for energy and must be manually fed. Though it requires more attention, its spectacular colour and movement make it a prized showpiece for experienced reef keepers. When well-fed, it opens fully both day and night, adding life and texture to shaded areas of the aquarium.

Origin

Native to the Indo-Pacific region, including the Coral Sea, Great Barrier Reef, Fiji, Tonga, Indonesia, and the Red Sea. Found in shaded reef caves, overhangs, and crevices, where light levels are low but planktonic food sources are abundant.

Feeding

The Sun Coral is non-photosynthetic and relies entirely on manual feeding for survival. It must be fed at least 3–4 times per week, though daily feeding yields the best polyp health and growth. Feed with:

  • Mysis shrimp or enriched brine shrimp
  • Finely chopped seafood (clam, shrimp, fish)
  • Marine plankton, rotifers, or coral blends

Feed when polyps are open — typically in the evening or after target feeding cues (such as introducing a small amount of food to the water). Each polyp should receive food directly via a pipette or turkey baster.

Lighting

Low lighting.Tubastraea does not require light for photosynthesis.

  • PAR range: <50 ¬µmol/m¬≤/s
  • Ideal for shaded or overhung areas of the aquarium.
  • Excessive light may promote nuisance algae growth around the coral’s base, so positioning in dim areas is preferred.
Water Flow

Moderate, indirect flow. Provide enough water movement to carry food particles and prevent detritus buildup, but avoid strong, direct currents that may prevent polyps from opening fully.

Placement
  • Place in shaded or low-light areas of the aquarium such as under rock overhangs, in caves, or vertical reef faces.
  • Can be attached to rockwork, overhangs, or placed on the substrate.
  • Ensure easy access for regular target feeding.
  • Allow 10 cm (4 inches) spacing from other corals to avoid irritation or stinging.
Tank Mates

Reef safe with caution. Compatible with:

  • Peaceful reef fish (gobies, wrasses, clownfish, blennies, etc.)
  • Invertebrates such as shrimp, snails, and hermit crabs
  • Other LPS or soft corals with adequate spacing

Avoid:

  • Aggressive corals that may extend sweeper tentacles into the Tubastraea colony
  • Fish known to pick at polyps (e.g., butterflyfish, some angelfish)
Aggression

Moderate.Tubastraea may extend short tentacles capable of mild stings to defend its space, but it is primarily passive. Ensure sufficient spacing from neighbouring corals.

Experience Level

Advanced. The Sun Coral’s non-photosynthetic nature makes it demanding — requiring regular, dedicated feeding and stable water parameters. Suitable for experienced aquarists ready to maintain a coral that rewards care with stunning, daily displays of colour and movement.

Water Parameters
  • Temperature: 24–27°C (75–81°F)
  • pH: 8.1–8.4
  • Salinity: 1.024–1.026 SG
  • Alkalinity (dKH): 8–12
  • Calcium: 400–450 ppm
  • Magnesium: 1250–1350 ppm
  • Nitrate: <10 ppm
  • Phosphate: <0.03 ppm
  • Tank Size: Minimum 100 litres (25 gallons); larger tanks provide better nutrient stability

Stable, clean water and consistent feeding are key to long-term success with this coral.

Reef Compatibility

Reef safe. The Sun Hard Coral is a spectacular, motion-filled coral ideal for shaded reef areas where photosynthetic species won’t thrive. When properly cared for, it will reward aquarists with regular polyp extension and vibrant colouration that stands out in any lighting setup.

Omegaverse
Format: Kindle
I was pleasantly surprised by this omega verse book. This 1 definitely had a few new twists And I really enjoyed reading it. The main female character was a badass and awesome. She had 1 best friend I wish we could have seen a little bit more of their friendship in this book. Her relationship with the male characters was good not to contrived or super instantaneous. And we had some fun plot twists that I didn't expect. I wish we had more of a follow up on the situation with her family her background and her mother who was a wench. I would definitely recommend this book.

Wow. Just wow. An amazing read
Format: Kindle
This book was eloquently written, or should I say the authors writing style is very eloquent? I loved the characters, and the story was quite compelling. I absolutely loved the FMC, she's a BA who doesn't take any crap & gives as good as she gets. A certain person certainly got his just desserts & then some, the earlier scenes of which were quite satisfying, had me punching the air & everything haha. All in all 20/10, great read

My opinion
Format: Kindle
Let me preface this by saying I really liked the story and the characters however, this book is in desperate need of some sort of editing. It's not misspelled words or formatting, but continuous run on sentences. Redundancies within the sentences. There were a couple of paragraphs that I had to go back and reread 3 or 4 times. Overall, I'd say it was worth the read.

Beautiful
Format: Kindle
I love omegaverses I had looked at this one multiple times thinking it's just another book about cocky rock star guys that let fame get to their heads and there are parts like that so I wasn't 100% off. I started reading the second book and met the fmc Astraea from the first one,after she had a run in with the aphla from the gym.😁 it gave me the push to stop and read book one first and im so glad I did this book was amazing their was so many characters I fell in love with hoping they will find their happily ever after. the guys were great, the plot was 🎯, and the ending had me 😭😭😭. I was wondering how nate could ever redeem himself, and he did. the last scene with him was sad, but I also felt it was beautiful. thank you to the author for making a beautiful omegaverse book that gave me all the feels. now I'm jumping straight into book two.

Knot their Omega
Format: Kindle
It took me a day to really get into the book, there is a lot happening in the beginning of the story. I wish there was more of a time frame because I felt like something’s happened quickly but they were farther away than I thought so that was a little confusing to me. I felt like there was so much happening but also not enough. As for the story itself I enjoyed it, it was different than other OV I’ve read. Bring the tissues, you will need them. They guys were great, I wish we saw more of Kai and Kenjis relationship. As for Nate…… IYKYK. I enjoyed this book, my first from this author and look forward to reading about Kamaris story. Book: ⭐️⭐️⭐️⭐️/5 Spice: 🌶️.5/5
