Is this normal frog behavior?

Is your frog still in the 10 gallon tank? Such a large enclosure can stress out a small Pacman and it won't feed while stressed. First thing I recommend is to get an ExoTerra Medium Breeder Box or similar; cover 3 sides with aquarium background or dark paper, and just add a water dish, shredded coco substrate mixed with dechlorinated tap, and a small silk plant. Place frog in it and get the whole thing inside your temperature and humidity regulated 10G tank. You can release frog into 10G once it reaches 3.5-4 in.

In regards to bottled water; there is no telling what is in there. Some companies add chemicals and other over filter it until it's safe for humans; but unsafe for frogs. It's better to get a bottle of Seachem Prime and treat your tap water with it.

Temperature inside the frog's box should be 82F with a slight drop at night. Humidity should be between 70-80%. A combo digital gauge is the best way to monitor these mandatory parameters.

Crickets should be sized same as distance between frog's eyes and gut loaded for 24-48 hours prior to feeding, with carrots, lettuce, oats, and cherios. Night crawlers can be cut from pointy end same as frog's snout to vent length. Would release couple crickets in box half hour before sunset and remove any uneaten ones the next morning. If your frog eats them can add more until it's satiated and stops feeding. For the worms just drop them in front of frog's mouth. Once frog calms down you can try tong feeding; but be aware that some of them won't eat from tongs.

Hope this helps and you can get frog eating soon. Keep us informed of progress and good luck !
