A coral block is a solid block that comes in five variants: tube, brain, bubble, fire, and horn.

A dead coral block is a dead variant of a coral block.

Obtaining

Breaking

Coral blocks can be obtained only with a pickaxe enchanted with Silk Touch; otherwise, they drop the respective dead coral block. Dead coral blocks can be obtained with any type of pickaxe.

Natural generation

Coral blocks and dead coral blocks naturally generate in coral reef structures. These are found in warm oceans.

Trading

In Java Edition, one coral block can be bought from wandering traders for 3 emeralds, while in Bedrock Edition, 3 of the same coral block can be bought for 1 emerald.

Example

Schematic of valid block placements for coral blocks
with water around. Several ways are shown where the
arrangement would cause coral blocks to stay alive
or die.

Coral blocks and their dead variants can be used as building or decoration blocks.

Sea pickle farm blocks

If sea pickles are planted on coral blocks, using bone meal on the sea pickles increases the number of sea pickles and creates more sea pickles on nearby coral blocks. Specifically, they can spread to the original sea pickle's level or one level below, out to a horizontal taxicab distance of 2. This is the only way to farm renewable sea pickles.

Dead coral blocks

In order for a coral block to stay alive, at least one of the six directly adjacent blocks must be water. If placed outside of water, it transforms into its respective dead coral block after a few seconds — a grayscale version of the coral block. A coral block will still die if the Gamerule randomTickSpeed is set to 0.

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 mobs and "fish blocks".
November 18, 2017					Coral were shown in a clip at MINECON Earth.
					Yellow coral, red coral, blue coral, and dead coral were shown (only one variant at the time), and in the clip slab variants of coral were shown as well, although they were not implemented.
1.13		18w09a			Added coral.
					Added dead coral.
		18w10a			The textures of all coral have been changed.
		18w10b			The single dead coral has been replaced with five dead coral.
					Dead coral in worlds before this update now stop existing when the world is updated.
		18w10d			Added coral reefs, allowing coral to generate naturally.
		18w14b			What was previously named "Coral" has been renamed to "Coral Blocks", and what was previously named "Coral Plants" have been renamed to "Coral".
					The blue, pink, purple, red, and yellow variants of all coral blocks and dead coral blocks have been renamed to tube, brain, bubble, fire, and horn, respectively.
		18w16a			Mining coral blocks now require Silk Touch to drop them.
					Coral blocks now have a short delay before dying.
					Coral blocks no longer die as long as one side is touching water.
		pre6			Living coral blocks now have new sound events: block.coral_block.break, block.coral_block.fall, block.coral_block.hit, block.coral_block.place, and block.coral_block.step.
Bedrock Edition
1.4.0		beta 1.2.14.2			Added coral blocks.
					Coral blocks currently die only if they touch air or void blocks, meaning that coral technically do not need water to stay alive.
					Added dead coral blocks.
1.5.0		beta 1.5.0.4			Coral blocks no longer die as long as one side is touching water.
1.10.0		beta 1.10.0.3			Coral blocks can now be bought from wandering traders.
					The texture of horn coral blocks has been changed to look the same as Java Edition's texture.
Legacy Console Edition
TU69		1.76	Patch 38		Added coral blocks.
					Added dead coral blocks.
Education Edition
1.4.0					Added coral blocks.
					Added dead coral blocks.
