ok first of all. you should but them in an inch of water. they are not aquatic frogs. they should have dirt of moss substrates be they like to hide by burrowing . and wait for food to pass by ambush attack. i wouldnt feed your pacmans or any frog feeder fish because they have parasites. i would stick with crickets twice a week and pinky treats few times a month. also wax worms, earth worm but not from a bait shop i would buy online dealer. i have a many years of frog expeirance and i have had my pacmans frogs for 8months and still looking great
