Hey KattChaos! Aaron has some great ideas for getting Medley more comfortable. Often times, when my frog doesn't feel like eating, it's because she's brewing a large stool. If it doesn't stress your frog out too much, you can try to feel her right side to see if you can feel a lump. Sometimes you can visually see it, too. If there is one, then it might be a good idea to give a warm bath with treated water (not too hot of course) for 15-20 minutes. It will encourage a bowel movement.

Otherwise, it may take some more time for Medley to acclimate to her new environment. Try Aaron's suggestion for covering the sides, take out the moss, and continue providing crickets to see if she eats any. Try leaving them in overnight (when Pacman's are most active) and be sure to count them so you can keep track. Also, if you remember who you bought her from, it wouldn't hurt to contact them about her eating habits before you purchased her. It might help to try and mimic her prior eating setup before she was sold.

If she's still not eating well after some time and you're unable to contact the dealer, it may be a good idea to experiment with feeding her. Maybe try feeding her with some bamboo tongs, or remove her from the tank to a new container to feed her. My friend had a similar experience with her baby Pacman not wanting to eat and his hunger strike went on for a long time before we tried putting him in a bucket, teasing him with a piece of worm on tongs...and bam! Ate it up. So don't be too discouraged.
