Hi, I've had a russian tortoise for about 2 years now and she's been living in a 20 gallon tank due to my colleges tank restrictions. I'm looking into a bigger tank for her but wasn't sure what size I needed. I've heard that 40 gallon tank is what she needs but also heard that she needs bigger. She is about 5inches right now so not full grown adult yet (8inches is her max size) so I wasn't sure what size tank to get for when she is her full growth. Is 40 gallon good or something bigger? I've also heard about building a tank but I cannot find anything about dimensions/supplies to do so.
