Hi, what is the actual temp inside the enclosure and what is the humidity at? if these aren't correct especially the heat it will turn your frog off from food. The heat has to be around 80f to 85f, I keep all mine at 82f and the humidity at 75%. You don't want the humidity going over 80%. At night you want a few degree temp drop, in the wild when the temps drop and it becomes dark this is when they come out to eat. As mentioned above they are nocturnal hunters, some will eat during the day but most keepers have more success at night. If you haven't covered 3 sides of his enclosure so he cant see out from every angle this is a good thing to do, sometimes being able to see to much stresses them out and makes them not want to eat. What was it being kept in when you bought it. If it was in something smaller then the 10 gallon you have now you may want to put him into something smaller or divide the tank in 2 with a divider. Sometimes to much space will stress them also, if they came from something small then get dropped into something way bigger its to much for them. Superworms aren't the best food for them because they can impact them. Crickets, roaches and nightcrawlers are the healthier choices as a staple and the others like hornworms, butterworms, waxworms, silkworms etc. are more for treats.
