I think this is awesome. Getting an animal can be a lonely thing. There is so much important prep work, for any animal!
Like it took me awhile to learn that the Repashy supplements and foods, sure they are one brand option, but are made by a super cool dude, Allen Repashy, who has been in the reptile hobby for decades. At some point literally writing the book on crested geckos in particular. Maybe it is not beardie specialty but there is a big world of herp culture people who do help each other.
There is always so much to learn and keep learning too. And people do things differently which can be okay, but also not. No calcium sand

, no sand for baby or juvenile dragons

, but a dig box with some play sand and organic top soil and clay is fantastic - especially for the half of beardies that will lay eggs eventually. No need to live in a sand box, but some sandish digging option for adult dragons is beneficial
