Newbie looking for some info

[Beardy]

Hi guys, I've really been debating wether to get a bearded dragon for a while now and really think I want to go for it.
I have a huge tank probably around 200 litres ( 50 gallon) and honestly not sure if it's suitable to house a beardie.
I've attached a picture and hope someone can help me out with some info.

I think you'd be better off with something with more length and width, and less relative height. A good standard for an adult beardie is 48"x24"x24" (sorry, I'm in the US, so I don't have the proper metric equiv). A smaller tank is okay for a baby, but I think with the height of the one you showed, you'd have trouble with the temps.
