Frequently Asked Questions
Symphyllia (Also known as symph or brain coral)
How do I care for Symphyllia?
Mid-tank on stable rockwork. They do well in most positions as long as they're not getting blasted with flow or cooked with too much light.
These are the classic folded brain corals with the maze-like patterns. Target feeding brings out insane colours - reds, greens, and everything in between. Well worth the effort.
Not feeding them. While they photosynthesise, they really benefit from the occasional meaty feed. You'll notice a massive colour improvement.
Fleshy, inflated appearance with vibrant colours in the valleys between ridges. The tissue should look healthy and full, not receding or showing skeleton.
Are Symphyllia suitable for beginners?
With some experience, yes. They're not the hardest coral to keep, but you'll want stable parameters and a bit of research under your belt first.
Plenty of newer hobbyists keep Symphyllia successfully - just make sure your tank is cycled properly and you're testing your water regularly. We'd suggest having at least a few months of reef keeping experience before trying these.
Our symphyllia are quarantined and settled before sale, which gives you a head start compared to stressed imports.
Where should I place Symphyllia in my tank?
Symphyllia can send out sweepers at night, so don't crowd them against sensitive neighbours.
They're not the most aggressive corals out there, but they can still damage nearby corals if placed too close. A few inches of buffer space is usually enough.
Ideal conditions: Low to Medium flow and medium light. Start in a spot that matches these conditions and give them a week or two to settle before considering any adjustments.
What tank parameters do you keep your coral in?
We keep all our coral in stable, proven parameters. These are tried and tested - our coral thrives in these conditions and will transition smoothly to similar setups.

Do you ship Symphyllia to my area?
Yes, we deliver UK-wide - from Cornwall to Scotland and everywhere in between.
All orders are packed in insulated boxes with heat packs during colder months to maintain stable temperatures during transit.
We ship throughout the week via Royal Mail Guaranteed or DX Live Stock services to ensure your coral arrives as healthy as possible.
What's your live arrival guarantee?
Every order comes with our live arrival guarantee.
If anything arrives dead or dying, send us a photo within 2 hours of delivery and we'll sort a replacement or refund - no arguing, no hassle.
We're confident in this because we settle and aquaculture all our coral in-house before it's ever listed. You're not getting stressed imports that might not make it through the first week.
Our coral has already proven it thrives in captivity before it reaches you.
How should I acclimate Symphyllia when they arrive?
Important: DO NOT drip acclimate coral!
Float the sealed bag in your tank for 20-30 minutes to match the temperature. Then open the bag and place the coral straight into your tank (or dip first if you prefer).
Place low on the sandbed for the first few days so the piece can get used to your tank conditions and lighting.
Why no drip acclimation? Some ammonia buildup can occur during shipping, but due to the pH drop in the bag, it becomes non-toxic. If you slowly add tank water with higher pH, that ammonia becomes toxic again and can harm or kill the coral. Temperature matching is all you need.
Don't panic if polyps are retracted at first - they often take a day or two to fully open up after shipping.
