Useful places to start
Start with the tools that interest you most.
Community Corals
Discover coral frags from fellow UK reefkeepers, or list your own home-grown corals for sale or free. Find reefers nearby and explore listings further afield where delivery is offered. Listings can also appear on CoralBay maps and Reef Route searches.
Explore Community Corals
Marine Marketplace
Buy and sell marine aquarium equipment, complete tank setups and staged tank breakdowns in a marketplace built for reefkeepers. Browse what's available or create your own listing, with collection and delivery options where offered.

CoralBay Protected Purchases
Look for protected delivery or collection options on eligible listings. Pay through CoralBay using Stripe, with funds held until the transaction is completed under the protection terms. Transaction stages are recorded, and there is a process for reporting problems. Direct payments arranged with a seller are outside CoralBay Protection; check the listing and terms before paying.
