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

Obtaining[edit | edit source]

Breaking[edit | edit source]

Coral blocks can be obtained only with a pickaxe enchanted with Silk Touch; if mined with a pickaxe not enchanted with Silk Touch, they drop the respective dead coral block.

Natural generation[edit | edit source]

Coral blocks naturally generate in coral reef structures, which can be found in warm oceans.

Trading[edit | edit source]

Coral blocks can be bought from wandering traders for 3 emeralds each.

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 can be used for building or as decoration blocks.

Placement[edit | edit source]

In order for a coral block to stay alive, at least one of the six directly adjacent blocks must be water or a waterlogged block. If placed outside of water, it transforms into its respective dead coral block after 3 to 4.95 seconds‌^{[Java Edition only]} or 2.25 seconds‌^{[Bedrock Edition only]} — a grayscale version of the coral block. A coral block still dies if the game rule randomTickSpeed is set to 0.^[1] Once a coral block dies, it is not possible to turn a dead coral block into a live coral block.

In Bedrock Edition, coral blocks do not die if they are surrounded by any non-air blocks.^[2]

Sea pickle farm blocks[edit | edit source]

If sea pickles are planted on live 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 only works on living coral blocks, not dead coral blocks.

Note Blocks[edit | edit source]

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

History[edit | edit source]

Java Edition Classic
May 21, 2009							Notch expresses interest in a suggestion regarding corals by user "solarblade".
Java Edition Infdev
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."
20100629							A coral block texture is added to terrain.png.
Java Edition Beta
May 17, 2011							An unused CoralTile class can be found in the jar file of a developer fork of Beta 1.2_02. The coral block would receive a randomized color depending on its coordinates.
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.
							Multicolored coral blocks were shown, alongside unimplemented slab variants.
1.13			18w09a				Added coral.
			18w10a				Each coral block variant now uses a unique texture.
			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 have been renamed to tube, brain, bubble, fire, and horn, respectively.
			18w16a				Mining coral blocks now requires 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.
1.14			19w05a				Added wandering traders, which sell all types of coral blocks, making them renewable.
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.
							Coral blocks with a damage/metadata value of 13 would display the following name: 'tile.coral_block..name'.
1.4.0			beta 1.2.20.1				Coral blocks with a damage/metadata value of 13 have had their name changed to 'tile.coral_block.blue_fan.name'.
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.
1.16.0			?				When buying from wandering traders, one emerald now purchases one coral block instead of three of the same type.
1.20.30			Preview 1.20.20.21				Decreased the hardness of coral blocks from 7 to 1.5.
							Increased the blast resistance of coral blocks from 0.9 to 6.
1.21.0			Preview 1.21.0.21				The different block states for the coral_block ID have now been split up into their own IDs.
Legacy Console Edition
Xbox 360	Xbox One	PS3	PS4	PS Vita	Wii U	Switch
