Dead Tube Coral is the dead variant of Tube Coral, formed when live coral is placed outside of water. It is one of five dead coral types, alongside Dead Brain, Fire, Bubble, and Horn Coral. Dead Tube Coral can be broken instantly with any tool. In Java Edition, a Silk Touch pickaxe is required to obtain it, while in Bedrock Edition, any Silk Touch tool can be used.

Once coral dies, it cannot be revived. It is mainly used as a building or decoration block. Like all dead coral types, it can be placed under a Note Block to produce a bass drum sound. In Java Edition, pistons can move dead coral as long as it remains supported in its new position.
