1000g female in 15qt tub temporarily?

How would a 1000g female do in a 15 qt tub for one day(in a rack)? She would be in there until more heat tape comes, then she's moving back to her 32 qt tub.

She'll be fine in there.

Perfectly fine. Not quite as big, but my 850g boy still doesn't want anything to do with anything bigger than 16 quarts as his regular residence.
