Thanks for the reply, elly.
I mist and fill his ponds with Deer Park spring water and use Aquatize in his pond water.
I'm usually gone during the day during normal biz hours.
I start feeding him around 7:15 pm. I'll put one loose in the cage to catch his eye and then another one or two in his bowl. I wait about 15 minutes and come back to see if he's come out and then add another four or five to his bowl. He always eats all his crickets (dusted with calcium six days a week and multivitamin once a week). The thing is that he used to eat them in front of me and now he hides until I leave and then eats. Nevertheless, he eats and poos like a champ and I worked from home yesterday and he was calling. I don't think he has any health problems physically, but he's obviously less comfortable when I'm around than he used to be. I used to talk and sing to him at mealtime and for a little while after and he'd chill on a saucer or climb around or take a soak after he ate, unbothered by my presence. I miss watching him and his cute little personality because he is usually hiding from me now.
