Tube Coral is a coral type found in warm ocean biomes as part of coral reefs. It is one of five coral variants, alongside Brain, Fire, Bubble, and Horn Coral.

Tube Coral can be broken instantly but can only be obtained with a Silk Touch tool. Without Silk Touch, it drops nothing. Using bone meal on dirt, sand, gravel, clay, or coarse dirt in a warm ocean biome can generate coral in place of some seagrass.

To stay alive, Tube Coral must be waterlogged or adjacent to at least one water block. If placed outside of water, it dies and transforms into Dead Tube Coral within seconds, and this change is irreversible. Like all coral types, Tube Coral can be placed under a Note Block to produce a bass drum sound. It is mainly used for decoration and aquatic builds.
