bag over plant = Bad
Also be careful of too much water, that pot is about 10 times large than the plant needs at this time. I've had 2-3 year old caapis in pots that big, so be wary of that.
when getting a new plant the order of importance:
1. Getting plant stable (this means don't do anything, just let it chill)
2. wait for a little growth, signifying that the plant is active and no longer in shock
3. repot if needed and find permanent situation for plant.
repotting, putting a bag over it's head, and a lot of other "helpful" things are only stressing the plant more.
