Im getting ... [20 letters]?

I believe you mean a Russian tortoise, not a Russian box turtle since there is no such thing. You have alot of research to do. Heat rocks are no good, give it a heat lamp for basking as well as a UVB light. Gl aquariums are horrible, and despite the fact they aren't the fastest animals, they still need alot of room to move, so a 20 gallon aquarium is no good. There's alot more to keeping them, so here is a good website you need to read: a href="http://www.russiantortoise.org" rel="nofollow"http://www.russiantortoise.org/a
