I really think my female Russian is suicidal. Not only does she constantly attempt to walk off of the highest points possible without hesitation but I now also have to make sure that there is no way she can have her nostrils below water when I soak her. If she can she will go to where the water is deepest and pull inside her shell even though she will be unable to breathe and just sit there like that until I panic and move her. Then she will try it again. The first time she did it I let her since I thought she would surely come out on her own. No I had to remove her from the water and she then began to have mucus come from her nose and mouth for about 20 minutes after.
