When using heat lamps you need a lamp with a dimmer switch so you can accurately control heat and light output. Next your bulbs wattage is too HIGH. You should not go higher than 50 watts. You could damage your frogs skin and eyes with high wattage bulbs. You should change to 50 watts.
The substrate needs to be Coconut fiber NOT husk. Cypress bedding is bad. If ingested accidentally it coyld cause iimpaction and death. Also when you switch to coconut fiber look for eco earth and plantation soil. These are the brands you'll want. The substrate must be moist not mud. Heavily damp is best.
He needs temps during the day of 80 to 82 F and night temps 75 to 79 F. At night stay around 77 or 78.
Humidity levels shoul be kept at 70 to 80%.
Hope this gives you some help with your new Pacman. Also be careful feeding too many meal worms. The chitin that their exoskeleton is made from cannot be digested by your frog. If he is fed too many he may become impacted.
Keep us posted on your little guy/girl.
