This is my husbands tortoise. I believe he's a russian but I'm not entirely sure. I just know that he usually gets to be a little less active around this time of year but this year he's very inactive. He goes days without moving or eating and my husband is starting to worry that he's dying. I noticed today that on both his eyes he has the white bubbly looking skin that completely covers his eyes. Is all of this normal? Is he sick or dying?
