When you purchase new frogs, always keep them separated from your other animals. Place the new frogs as far away as possible from other animals, preferably in a separate room. Set the cage up very simply (don’t clutter up the cage with too many items) so that you can monitor the frog’s activity, eating habits, and stool samples. Place only a plant or two (for hiding areas) and a water bowl in the cage; the best cages are shoe boxes or sweater boxes. If your new frog seems healthy after 12-16 weeks, then you can introduce it to your other animals. However, if you notice any strange insects attacking your frog or the frog’s feeder insects, take the frog to a good herpetological vet. Worms in stool samples are also a huge warning sign of serious health problems. Animals not eating, not gaining weight, or experiencing stunted growth should always be a concern. The bottom line is that you need to make sure a new frog is treated and doing well before introducing it into your existing population.
