Fire Coral
minecraft:fire_coralFire Coral is a non-solid decorative block that naturally generates in coral reef structures within warm ocean biomes. It must be mined with a Silk Touch tool to keep it alive, since it survives only while touching water and quickly dies into Dead Fire Coral otherwise.
