Dead Coral

A dead coral is the dead variant of coral. There are five variants total: tube, brain, bubble, fire, and horn.

Dead coral can be broken instantly with any tool. It can only be obtained with any Silk Touch enchanted tool in Bedrock Edition or a Silk Touch enchanted pickaxe in Java Edition.[1]

Dead coral is created when coral is placed out of water. When live coral is placed outside of water, it dies and transforms into its respective dead coral after 3 to 5 seconds. Coral dies even when the game rule randomTickSpeed is set to 0.[2]
