Before administering any medicine, you need to be sure that the frog is sick. Therefor you should keep a close eye on them, so you can intervene if necessary. If you are not sure about your diagnosis, don't hesitate and ask for help. Placing the animal in quarantine should keep any contagious diseases from spreading among the other animals.

One of the disorders found among the frogs is stress, caused by prolonged captivity
in a small area or a vivarium with to many frogs in it. Messy vivariums and too much exposure to humans can also cause stress.

Symptoms: animals won't eat and/or lay on their backs while twitching (often occurs with young animals). If you buy a new frog, place them in a small dish with some tepid water and a teaspoon of honey. Place the animal in quarantine after 30 minutes. After 30 days you can put the frog in the vivarium with the other frogs.
