Coral

Coral is a type of non-solid block that comes in five variants: tube, brain, bubble, fire, and horn.

Dead coral is the dead variants of coral.

Obtaining

Breaking

Coral and dead coral can be mined instantly but can be obtained only when mined with a Silk Touch enchanted tool.

Dead coral can only be obtained with a Silk Touch pickaxe.^[1]

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. In Bedrock Edition, the same can happen in any biomes as long as bone meal is used in a water source above the aforementioned solid blocks.

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

Usage

Coral can be used as a building or decoration block.

Dead coral

In order for coral to stay alive, at least one of the blocks surrounding it must be water or a waterlogged block. If placed outside of water, it dies and transforms into its respective dead coral after 3 to 5 seconds. Coral dies even when the game rule randomTickSpeed is set to 0.^[2]

Dead coral cannot be turned back into living coral.

Note Blocks

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

History

Java Edition Classic
May 21, 2009			Notch expresses interest in a suggestion regarding corals by user "solarblade".
Java Edition Alpha
June 28, 2010			Notch mentioned on his blog: "I tried adding corals, but it's really hard to draw a single block that looks like corals, since it's really more about crazy amounts of variation and diversity. But I do know that the corals will have tiny fish particles around them."
Java Edition
October 5, 2012			Coral were jokingly teased in the fake snapshot 12marc40awesome, along with fish as mobs and "fish blocks".
November 18, 2017			Three types of coral were shown in a clip at MINECON Earth.
1.13	18w10a		Added coral plants.
	18w10b		The texture of red coral plants has been changed.
	18w10d		Added coral reefs, allowing coral plants to generate naturally.
	18w14b		"Coral Plants" have been renamed to "Coral".
	18w14b		Blue, pink, purple, red, and yellow coral plants have been renamed to tube, brain, bubble, fire, and horn coral, respectively.
	pre6		5 new sound events that apply to coral have been added: `block.wet_grass.break`, `block.wet_grass.fall`, `block.wet_grass.hit`, `block.wet_grass.place`, and `block.wet_grass.step`.
	pre10		Coral can now be collected using Silk Touch. Prior to this, coral was completely unobtainable in survival.
1.13.1	18w31a		Bone meal used in water of warm ocean biomes now has a chance of growing coral, making them renewable.
1.13.1	18w32a		Added dead coral.
