hey there man, in reguards to your sick frogs, is there an exotic pets vet to whom you can take them to get checked out? they're a species that lives over water, and thus your tank set up needs to have at least a large bowl of water for the frogs. i would take them to the vet if you have one available. here are 3 great links for info and care of reed frogs. hope this is hepful, and i hope you dont lose any more.
