My Goni garden !

Is that real coral? They are very nice. Is it possible to create real coral in the aquarium? Need help... i am a beginner.
It is a real coral, I’m curious how Lesely’s tank is doing I haven heard from her in some time now. Those are goniporia or “flowerpot coral” and often bought by beginners but it is a very hard to keep coral for beginners and most end up dead in a few weeks. A similar coral is alvapora which is much easier to keep.
