Your Pacs temps need to be 80 to 85 during the day and 75 to 79 at night. 70 is too cool.

What are your humidity levels? They need 70% to 80%.

Do you use De-chlorinated water or Spring water?

Do you dust your frogs food with a multivitamin once a week and a calcium supplement everyy other feeding?

Have you tried givinng your frog worms now or a pinky?

How often do you change your frogs substrate? And do you expand it with de-chlorinated water or spring water?

Here's what I want you to do. For a energy boost for your frog prepare a bath that is no deeper than just below your frogs chin. The bath should be luke warm and be de-chlorinated water. Disolve 3 to 4 drops of honey in the bath then place your frog in. Let uour frog soak for 10 to 15 minutes then place your frog back in his/her enclosure. Let him/her be for a little bit then try to feed. If food is refused I want you to force feed your frog.

Do you know how to force feed a Pacman?

Keep me posted.
