Dead Horn Coral Fan is the dried-out, pale gray skeleton of a horn coral fan — a wall-mounted coral decoration introduced in Minecraft Java Edition 1.13 and Bedrock Edition 1.4.0. The block forms whenever a living horn coral fan loses access to water: in Java Edition the live fan dries after 3 to 4.95 seconds outside water, while in Bedrock Edition the transformation is instant. Live horn coral fans generate naturally inside coral reef structures in warm ocean biomes, so placing one on dry land is the simplest way to farm Dead Horn Coral Fan as a building material. The dead fan keeps the branching, antler-like silhouette of the live block but loses all color, dropping the vibrant yellow of horn coral for a uniform bleached gray. With a hardness of 0 and a blast resistance of 0, Dead Horn Coral Fan breaks instantly to any tool and is destroyed by explosions, so Silk Touch is the only way to pick it up and relocate it in Java Edition.

Builders reach for Dead Horn Coral Fan when a build calls for bleached, weathered coral textures — ruined underwater temples, sun-bleached reefs, fossil displays, or pale organic detailing on walls and floors. Dead Horn Coral Fan is fully renewable, because live coral can be grown with bone meal in a warm ocean and then dried out to produce an endless supply. Unlike the live variant, Dead Horn Coral Fan no longer needs water to survive, so it can be placed anywhere without a hydration check. The block is non-flammable and gives off no light, but its hardness of 0 means a creeper blast or a single punch clears it, making Dead Horn Coral Fan a fragile accent rather than a structural block. For monochrome coral builds, pair Dead Horn Coral Fan with the matching Dead Horn Coral Block to extend the same gray tone across full cube faces.
