Pacman Frog Eating Problems

[PacManMan]

Hey guys,
I have an Albino Pacman Frog that has not eaten in about 2 months and im getting more and more worried. His svl is about 3 1/2 inches. He has not lost any weight and still looks like he has just eaten. I'm using eco earth as a substrate and maintain a tank temperature of about 75 farenheit. I do not have a humidity gauge in there but im going to get one soon and i will tell you the humidity. So thanks for all the help you guys will give.
