Is your pacman a creature of habit? Mine is indeed a night owl. By day he's buried in the coconut fibre substrait, sometimes totally, but usually so one eye is visible. At night within minutes of my turning off the light, my frog reveals himself. I'll feed him/her then, and my frog has a good appetite. Then he/she will climb into the waterdish, usually to poop. Then my frog will climb on the glass wall of the tank for a bit, then stand in a corner for a time. Eventually Ill find my frog sitting in the middle of the tank. Once I turn the lights back on in the morning- he will slowly start to burrow- by the time I leave for work, he's totally burrowed again
