I have the same problem with my balls. I have a male and female and have never seen either one soaking in the water bowl. Then about 2 days ago mine start soaking. They go in and out, but spend most of there time in the water. They are in there at the same time. Mine go through cycles where they like to sit under the substrate for a few weeks then they like to sit in the hides. Now they are sitting in the water bowl.
