I have left my frogs at home while going on vacation for 3 - 4 days. I just over fed them and misted real heavy the day we left. I also added in more springtails to the Dart and Mantella tanks to give them more snacking opportunities. Everything worked out great, but like Bill My tanks are pretty good at taking care of themselves and the frogs can go for a week or so without substantial feeding and be ok. It is hard to leave them, but they will be fine
