Since you are new to reptiles, I'll also give you the basics on Russian tortoise care. Of course, you can ignore whatever you already know. Please don't rely on a pet store for care information. While we should be able to rely on such information, unfortunately, it is often wrong. They sell people the wrong lighting, advise the wrong foods, and often don't know the correct temperatures for the various reptiles. After months of things not being quite right, the animal becomes ill.
A glass -sided enclosure or tank isn’t the best environment for tortoises to live in because the air can’t circulate properly. That can contribute to skin and respiratory infections. They should have some kind of an open enclosure that is at least 4 feet long and 2 ft. wide, and 1 to 2 ft. deep. You could build such an enclosure or convert a preformed garden pond or child’s plastic wading pool (one of the larger sizes). Large RubberMaid totes can also be converted. Here is a site where you can see photos of indoor and outdoor homes for tortoises:
It's important to have a digital probe thermometer to check temperatures because incorrect temperatures can also lead to many different health problems. The gradient in the enclosure should be 70*F to 85*F, with the basking area warmer yet, at 95*F. Night temperatures can go down to 70* to 75*F, so you probably don’t need to leave the heat on at night. Tortoises need the night time drop to stay healthy.
In sufficient UVB light can also lead to skin infections and even more serous health problems. even though you have a UVB light, little is reaching your tortoise. UVB light shouldn't be placed on top of screens. A wire or plastic screen blocks 50% or more of the rays, resulting in too little reaching the tortoise. In addition, the spiral bulbs are often inconsistent in their output. They can put out so much that they damage the eyes, or so little, that they don't prevent health problems. Also, pet stores often don't inform customers that UVB lights only last for 6 months. Make sure the light you bought really is a UVB. UV, UVA, DayGlo, and full-spectrum are not the same thing. I recommend the Reptisun 10.0 in the straight tube style.
Diet is very important. Tortoises need a high fiber diet. Greens are important, but greens alone don't contain enough fiber, either. Hay and grasses should be a big part of the diet. Buy some tasty varieties of hay. The one available at this site is put together especially for tortoises.
You can also find timothy hay in the rabbit department of pet stores. Hay should be available at all times. A calcium source is also needed. The easiest way to provide that is to place a cuttlebone in the enclosure. Cuttlebones are inexpensive and are sold in the bird section of a pet store. You can read much more about diet at the following reputable site:
The same site has a good care sheet:
