Breaking
Coral can be mined instantly, but can be obtained only when mined with a Silk Touch enchanted tool.

Natural generation
Coral naturally generates in coral reef structures found in warm ocean biomes.

Post-generation
When using bone meal on dirt, coarse dirt, sand, red sand, gravel, or clay in warm ocean biomes, coral generates in place of some of the seagrass.

Dead coral is created when coral is placed out of water.

Usage
Coral can be used as a building or decoration block. If it is not adjacent to a water block, it quickly transforms into dead coral.

Dead coral
In order for coral to stay alive, at least one of the blocks surrounding it must be water. If placed outside of water, it dies and transforms into its respective dead coral after a few seconds.

Dead coral cannot be turned back into living coral.

Note Blocks
All types of dead coral and coral can be placed under note blocks to produce "bass drum" sound.
