That's the beauty of PDF's, their food consists of fruitflies and springtails. As long as I give the frogs plenty of food before I leave for a trip, I can leave for 2 weeks and come back and in most cases they have multiplied!!! Very low maintenance, Especially if the tank is seeded with springtails! The timers and misters do all the hard work. I'm actually working on expanding the frog room to accommodate another 12 tanks and fruitfly culture and some more tadpole space!
