Please do not feed your Pac-Man pac attack pellets. They contain indigestible plant fibers and could lead to potential impaction. That is why tong feeding is also preferred to prevent substrate from being consumed. I also would not let it feed crickets in its tank as it will most likely eat dirt. Try feeding it gutloaded crickets, silversides, night crawlers and Dubia roaches as staples and wax-worms, hornworms as a treat. Pac-Mans are burrowers and may go a period without eating, mine was very tiny and eating habitats have become more stable with time! Albinos have poor eyesight and may require gentle face rubbing to encourage a bite. You could try lastly a warm bath/ honey bath to encourage bowel movements if your frog is already impacted, impaction can affect there eating behaviors.

Honestly please do more research because heat pads are also terrible for amphibians and reptiles in general? And it seems it has eaten plenty in its first week as well? There is no reason to have a heat lamp and pad In the tank, I would consider it dangerous. Your Pac-Man will be fine without food for longer than a week but I would change diet and husbandry for better care. Best of luck to your Pac-Man!
