Tube Coral Block

The Tube Coral Block is a decorative block in Minecraft, a type of coral block. It is blue in color and naturally generates in coral reefs within the Warm Ocean biome. Players cannot craft Tube Coral Blocks; they must be mined using a pickaxe enchanted with Silk Touch. Mining it with an unenchanted pickaxe will result in a Dead Coral Block drop. Tube Coral Blocks only maintain their vibrant color when surrounded by water; if placed out of water, they will turn into a gray Dead Coral Block after a short period. Tube Coral Blocks are commonly used for building and decoration, and can be used with sea pickles to increase their yield. In creative mode, players can find Tube Coral Blocks in the inventory and generate them with command blocks. Their item IDs vary across different versions, and players can obtain them using respective commands.
