FIRST of you need to read up on the pacman frog ASAP. gravel is probally the worst thing to keep them in i use bed a beast with a small water dish,which works great. second stop feeding your freaking frog mice they shouldnt be fed that all the time its high in fats and the lipids can cause blindness over time. crickets, wax worms, melworms, with dusting them once a week will be a good diet for it so make some changes ASAP then post a pic of your setup.
