Coral Fan

Breaking
Coral fans and their dead variants can be mined instantly, but can be obtained only when mined with a Silk Touch enchanted tool. Breaking coral fans without Silk Touch destroys the coral fan.

Dead coral fans can only be obtained with a Silk Touch pickaxe.

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. $$, coral fans can also be placed outside of water as long as one of the blocks surrounding it contains water. If placed outside of water, they transform into their respective dead coral fan immediately or after a few seconds.

Wall Coral Fans
Wall coral fans cannot be obtained through vanilla means. $$, they are completely unobtainable, but $$, they can be obtained through add-ons or inventory editing, though the item form is badly glitched to the point of being completely nameless.

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

Placement
All coral fans (and their dead variants) can be placed on the four sides and the top surface of blocks; they cannot be placed on the bottom surface.

Pushing with pistons
Live coral fans cannot be pushed by pistons (attempting to do so results in the coral fan breaking). Dead coral fans can be pushed by pistons as long as they will still be "supported" in the new position (not floating).
