Lija gave you some good advice. Also, myself would bring up the temperature to 82F with a few degrees colder at night. Can get
not dyed night crawlers at Walmart or a local bait shop. For a 2 in. frog; can cut them to that length until frog reaches 3 in.; then feed whole ones. Some more info on dusting in here:

Do you mix the coco substrate with dechlorinated tap? In regards to bloating; can you describe how it feels like and respond to gentle touch? Does is feels solid, jelly like, or fluid (moves like in waves)? If it pooped last Monday; frog should not be impacted 4 days afterwards. After doing a honey bath; a 20 min. "rinse" in 80F dechlorinated tap is recommended.
One last thing is that a 10 gal. tank is large for any Pacman under 3.5 in. and could be a source of stress. Finally, recommend keep this frog away from others and not to share any husbandry equipment or food items with other frogs in your collection until it's clear of any possible issues. Good luck
