Can you revive dead coral in Minecraft?

No. Once coral, a coral block or a coral fan turns into its grey dead variant, it can never become living coral again. Keep living coral touching water to prevent it dying.

Why did my coral drop nothing when I mined it?

Living coral and coral fans drop nothing unless mined with a Silk Touch pickaxe. Living coral blocks mined without Silk Touch drop only the dead version of the block.

Can you farm coral blocks?

No. Full coral blocks are not renewable and only come from natural reef generation, plus the occasional wandering trader sale. Coral and coral fans can be farmed with bone meal in warm oceans.

Where do coral reefs spawn?

Only in warm oceans, the teal-water oceans usually found next to deserts, savannas and mangrove swamps. Look for shallow, colourful gardens full of tropical fish.

Coral is the most beautiful block family in Minecraft and the most fragile. Haul it out of the sea carelessly and the rainbow turns grey in your hands, permanently. But handled properly, coral becomes a builder's treasure: living colour for aquariums, fans that pass for flowers, and dead grey skeletons that blend with stone. Everything starts with understanding what the three forms actually are.

The Three Forms and Five Colours

Form	What it is	Renewable?
Coral	Branching, non-solid plant-like pieces	Yes, with bone meal
Coral block	Full solid cube, the reef's building mass	No, natural generation only
Coral fan	Small flat fan, places on tops and walls	Yes, with bone meal

Every form comes in the same five varieties: tube (blue), brain (pink), bubble (magenta), fire (red) and horn (yellow). Each also has a dead variant, completely grey. Death is a one-way trip: living coral can die, but dead coral can never be revived.

Where Coral Reefs Generate

Reefs only form in warm oceans, recognisable by their teal-tinted water and their habit of bordering deserts, savannas and mangrove swamps. Not every warm ocean has a reef, but most do, and a reef is unmissable from a boat: a shallow garden of colour full of tropical fish, the odd pufferfish, and sea pickles glowing on the floor. In Bedrock, some dead coral generates naturally among the living; in Java, every grey piece you see was once alive.

Collecting Coral: The Silk Touch Rules

This is where most coral is lost. To collect living coral as a living item, you need a pickaxe with Silk Touch. Break the rules and the results are unforgiving:

Living coral block, no Silk Touch: you get the dead coral block.
Living coral or coral fan, no Silk Touch: you get nothing at all.
Dead coral blocks mine normally, but dead coral and dead fans still need Silk Touch to drop.

Coral and fans break instantly; full blocks take a moment even with a good pickaxe. Plan your reef raid around an enchanted pickaxe, not your fists.

Keeping Coral Alive in Your Builds

Living coral survives only while it is in contact with water. Full blocks need water directly against them; coral and fans just need water adjacent or to be waterlogged themselves. The flexible part is that any waterlogged block counts: a waterlogged stair, slab or leaf block beside your coral keeps it alive, which lets aquarium and garden designs hide the water almost entirely. Forget the water and the coral dies within moments of being placed, so set up the water first and decorate second.

Farming Coral and Fans

Full coral blocks can never be farmed; what the ocean generated is all there is, short of the wandering trader, who occasionally sells one for 3 emeralds. Coral and fans, though, behave like plants. Use bone meal on sand, gravel, clay or dirt underwater in a warm ocean and coral and fans sometimes sprout among the seagrass. Bone meal used on the side of a living or dead coral block in a warm ocean is even better: it is guaranteed to grow a wall fan there. Outside warm oceans, none of this works.

Putting Coral to Work

Living coral is pure decoration and all the better for it; fans in particular make superb flower substitutes on dry land builds, as long as you waterlog something beside them. Dead coral earns its keep too: the grey blocks sit naturally beside cobblestone, andesite and basalt, and dead fans are a working part in many TNT duper designs thanks to how they sit on block sides and move with pistons. Beautiful, fragile and secretly technical: coral rewards the players who bother to learn its rules.
