Hi and welcome to Frog Forum
I keep several Xenopus laevis myself and there are many on the forum that keep them as well. Since these frogs are carriers of the deadly fungus, chytrid, many countries have banned them, so you need to check with the laws of your country. A nice looking frog from Norway as well as most of Europe and Asia is the moor frog (Rana arvalis), you might find one in the wild if you live in southern Norway.
Take a look at these websites:
