I got a new Russian Tort 3 days ago, and I have been using the zoo med power sun 100w light about 12 hours during the day, and then a night bulb that is 75w and is supposed to imitate the moon. Petsmart told me she needed it, but after reading deeper info I'm not so sure. Is it needed or[/align] recommended for a russian tort to have a night time bulb, or is it better not to have one?
