Need more info, based on what you said so far - you need basking spot at about 32-34C during a day. Humidity is a bit too high as well, however bicolors can tolerate a bit higher humidity then waxies, you will need to keep it under 50, 60 is ok occasionally.

Do you have uvb? If so how strong?

pics of the frogs are needed, not getting exactly what antibiotics were used and why. You need to get their poop tested. WC will always have a heavy parasite load, it's needs to be fixed asap in captivity.

vivarium - can't see, it's it glass or mesh?
