I just got a new almost adult male Russian Tortoise. He is in his new digs getting used to it. I just picked him up and like him. I am going to name him Russell the Russian Tortoise! I am hoping that he gets comfortable soon in his new habitat and starts to eat. He is in a 50 gallon rubbermaid trough for livestock. It has a ceramic heating element on one end with a UVB lamp also. Then he has a hide on the other side. Substrate is cypress mulch. I am looking forward to getting to know him. I have read all the care sheets available. I used to have a colony of Russians and hibernated them. I do not plan to hibernate Russell.
