I just got my pacman frog (fantasy) 1 month ago, when i first got him home, he ate a small grasshopper right away and the first 2-3 weeks he ate a grasshopper or mealworm every day or so, but a little over a week ago he just stopped eating?

The temperatures are 26-29 celsius (78-84 Fahrenheit) during the day, and goes down to 23 celsius (73.4 Fahrenheit) at night, i keep the humidity up at around 70-90% with daily mistings. He is roughly 2 inches in length.

If anyone knows how long he can go without food at that size before it starts to get unhealthy i would like to know. Thanks in advance.
