Hermit
This guy is a handy element of your clean up crew!
Hermit crabs are excellent additions to reef tanks, helping control algae and clean up leftover food. They are peaceful scavengers that live in empty shells, and they will occasionally change shells as they grow. These crabs are active, hardy, and well-suited for community reef environments, making them a great part of any cleanup crew.

Frequently Asked Questions
Crab Coral
How do I care for Crabs?
Are Crabs suitable for beginners?
Yes, absolutely! Crabs are one of the easier corals to keep and a brilliant choice for newer reefers.
They handle small parameter swings well and settle into most tanks without fuss. As long as you've got the basics right - stable salinity, temperature, and decent lighting - you'll do fine.
We settle all our crabs in-house before listing, so they're already adapted to captive conditions when they arrive at your door.
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.
Magnesium
1400
Alkalinity
8.4 dKH
Calcium
430-440
Phosphate
0.05-0.1
Nitrate
10-20
Do you ship Crabs 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 Crabs 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.
