Its vet time. I know not alot of vets do reptiles, but try to find one. Make sure you seperate them (the frogs) and obtain a sure fecal sample from your froggies and have them check it. You might have one with a high parasite load, or you might have one thats sick. If you can't find a vet try to find a herpetologist or biologist in your area (look at a local college or highschool, science teachers are great for this) Ya need to check da poo!
If theres any other things you can tell us about setup that might help, we'd love to hear.....but right now you need a vet to save your froggie. Good Luck! Tell us how it goes.
