Coral Fan

Coral fans are non-solid blocks that come in 5 variants: tube, brain, bubble, fire, and horn.

Dead coral fans are the dead variants of coral fans.

Obtaining
Coral fans and their dead variants can be mined instantly, but can only be obtained when mined with a Silk Touch enchanted tool.

Natural generation
Coral fans and dead coral fans naturally generate in coral reef structures.

Bone meal
When bone meal is in Warm Ocean biomes, it has a chance of generating coral fans.

Dead coral fans
In order for coral fans to stay alive, they must be placed in water. If placed outside of water, they will transform into their respective dead coral fan immediately or after a few seconds.

Usage
Coral fans and dead coral fans can be used as a building or decoration block.

Placement
All coral fans (and their dead variants) can only be placed on the 4 sides (north, south, east, and west) and the tops of blocks - placing them on the bottom of a block won't work.
