Hi again, the first thing I would do is get some liquid calcium into him like I suggested before because he really needs some calcium in his system. You never know this might give him some extra energy and he may become more eager to eat. I know sometimes when I don't eat right for a week or 2 when I get busy I start to feel sluggish and exhausted, once I get back to eating properly and get some of the vitamins and protiens I lacked during the 2 weeks I feel a lot better and more energized. For the eating if you try the feeding in a separate container what I would do is scoop him up and put him in the container your going to use, find the darkest room you have in the house and just let him sit in the tub for 10 minutes or so to calm down. When doing this I would just leave room then come back after the 10 minutes. When you go back in put the crickets in then just leave the room again for a little bit then go back in and check if he has ate anything, and I would remove the back legs of the crickets so they cant jump away and they cant rub the vitamins off as fast. For the tongs I had one that wasn't fond of them at first and every time I went close to him with them he would turn or puff up and go into self defense mode. What I did is I would lower the cricket down to the coco fibre with the tongs so the cricket was actually touching it, then I would let the cricket go running in the direction of the frog and most the time he would scoop it up. I started from about 3 inches away from him and over the next little bit I would just go closer and closer, eventually after about 2 weeks he figured out the tongs weren't going to hurt him and they meant food and he was jumping at the crickets because he didn't want to wait. And when doing this I would take the back legs off so they couldn't jump. What does his poop look like? You may want to bring him to vet soon if nothing works for you and get him checked out, you never know he could have some type of worms and this could set him off food.
