Atoll is a living library of saltwater coral. Atoll can help you identify photos of coral. Browse through beautiful coral images to find new ones that might fit well in your reef tank, or get information on coral you already own.

Each coral page in the library has scientific info as well as important hobby information about what conditions are necessary to keep the coral healthy.

Own a coral, but don’t know which one it is? Submit a photo of your coral for other Atoll users to help identify. Once your coral is identified, you can tap your submission to see the library page for that coral. You can also help other users identify the corals they have submitted.
