This article is about the solid block. For the non-solid plant, see Coral. For other kinds of corals, see Coral (disambiguation).

Coral blocks are solid blocks that come in five variants: tube, brain, bubble, fire, and horn.

Dead coral blocks are the dead variants of coral blocks.

Obtaining

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

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.

Dead coral blocks

In order for coral blocks to stay alive, at least one of the orthogonally-adjacent blocks must be water. If placed outside of water, it will transform into its respective dead coral block after a few seconds. They are a grayscale version of coral blocks. Maximum density of living corals is reached when water blocks are a chess knight's move apart, like in a bamboo farm.

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 blocks were shown in a clip at MineCon Earth. Horn coral, fire coral, tube coral, and dead coral were shown (only one variant at the time), and in the clip slab variants of coral were shown as well.
1.13			18w09a		Added coral blocks, which at the time were called simply "coral", and the tube, brain, bubble, fire, and horn variants were named blue, pink, purple, red, and yellow, respectively.
					Added dead coral blocks, which at the time were called dead coral and did not have any variants.
			18w10a		Changed texture of all coral blocks.
			18w10b		Replaced the single dead coral block with five dead coral blocks (once again, called dead coral at the time). Like coral blocks, they were blue, pink, purple, red, and yellow at the time, but were later changed to tube, brain, bubble, fire, and horn.
			18w10d		Added coral reefs, allowing coral blocks to generate naturally.
			18w14b		Renamed what was previously called coral to coral blocks, and renamed coral plants to coral.
					Renamed the blue, pink, purple, red, and yellow variants of all coral blocks and dead coral blocks to tube, brain, bubble, fire, and horn, respectively.
			18w16a		Mining coral blocks will now require Silk Touch to drop them.
					Coral blocks will now have a short delay before dying.
					Coral blocks will no longer die as long as one side is touching water.
			1.13-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			beta 1.2.14.2		Added coral blocks. At this time, coral blocks would only "die" if they touched air or void blocks, meaning that coral technically did not need water to stay alive.
					Added dead coral blocks.
1.5			beta 1.5.0.4		Coral blocks will now no longer die as long as one side is touching water.
Legacy Console Edition
TU69		1.76	Patch 38		Added coral blocks.
					Added dead coral blocks.
Education Edition
1.4.0					Added coral blocks.
