If it were mine, I would just put it back in its original container for now, and let it grow there till early Spring. Light levels and intensities are getting shorter now, so it is not really the time to repot them. I would not do terrarium setting for it either, it will just be problematic with drainage and excess moisture.
In mid to late Spring, that will be the time I will repot to a wide mouth, but shallow container with drain holes in a gritty media mix to allow more area to grow.
