How should I make branch like coral reef things?

So right now I want to make a coral reef for my game, and this design is what I would want to go for for the coral itself.


Are there any plugins or anything that I would be able to use to make these branch type things? Or would I have to make the whole thing manually?

that is a mesh that’s probably made in blender, using the same technique to make trees they probably made coral reefs with it
there are tutorials on youtube on how to make trees in blender, if you play around and deviate a bit from the tree tutorial you can probably make corals with it
