I applogize for the wrong signal sent. He will soak in the dish but they only swim out of necessity. When in shed they will soak and/or use humidity box also. As for taming, the more he sees you and household will help acclimation. Commerical foods do help with the lack of supplementation/nutritioin/mineral & electrocyte intake. A natural diet is very good also. Good luck, hope I helped alittle.
