@ goreptiles: I don't want to risk any accidents, I will just let the feeding be done in the tank since I will replace the substrate once a month...

@ Deku: Thx! So you would recommend me to just leave it alone and not feed it? Will the pacman give out any hint that hes hungry and ready to eat?

Thank you for your input! Like I said before, this is the first frog that my gf and I own and I just want this experience to be in a positive note... more input is appreciated~
