I got this Rebutia Muscula about a month ago. It seems to be doing well, and beginning to bud, but I'm worried about it's growth. See images below, it is definitely elongating, which I don't mind but I want to make sure it isn't doing it in a way that is going to be harmful down the road.

It gets full sunlight all day. It sits outside my southern facing window. I water only when the soil is dry. I bring it inside at night, because I don't want any creatures nibbling on it and the lows are dipping unseasonally.
What do you all think? Should I change anything, or accept my little cactus the way it is?
