Is this a suitable diet for my little pacman

[Pacmanfrogger]

I currently have him housed in a 10 gallon terrarium with 3to 4 inches of coconut substrate kept at 80% humidity I can only get the temp around 76 with a 50watt light wondering if a 76 would be more suitable but on to diet I try and feed him 1 horn worm and ten crickets once a week then ten crickets and a couple wax worms every day he will eat all of them then hop around or awhile and soak afterward seems to be happy just. Not sure if it is the most healthy I could keep him
