Mold on moss? repot needed?

[Nomeatbag]

Hi im very new to Bonsai,
Today i was sorting out my plants because mold had spread on the soil(cheap soil and bad circulation) and noticed my chinese elm bonsai (kept it inside), that i bought a week ago, had mold on the moss too (atleast i think it is mold??) but it looks very different than the other plants. (see pictures)
I was goning to repot/change the soil but i only want to do it if its really necessary, i don't want to harm the little Tree..
So i thought that i ask first.

Get that tree outside in the sun and the problem will go away.
Conversely, you can keep it inside but it will die.

Thank you, when i bought it i thought it could be kept inside, they sold this bonsai in the homeplant section of the store, so i assumed.

Maybe i shouldn't do everything on the fly.
At least this teaches me to do more research before buying.
I have to figure out where to put it now tho.

Thanks again.

Chinese elm is fully winter hardy in Germany. Just get it outside. Start with a half sun position. Check it daily to see if it needs water, water only if needed. Get itside now so it has time to adapt for winter.
