Hi Dennis:
I always try to give my pedes fresh greens, veggies and fresh fruit. All food starts to rot and get moldy after a day in the tank, so change the food everyday. When i went on a trip for like a week or more, I'd always give them Bearded Dragon Lizard food. The large pellets. Being that it's dry food, it won't rot or get moldy. I'd always put it into a plate so it won't come in contact with the damp soil. I have a large jar of water with my Ultrasonic Fogger device in it to create a rain forest "fog" to keep the plants and millipedes happy and it also keeps them from dehyrdrating to DEATH! I have my large 55 gallon tank arrange in a way so that just the one side of the tank get's "fog" and if the pedes want to get away from it, all they have to do is crawl to the other side. I'd also put the food far far away from the "foggy" area so it won't get wet and mold on me. When i come back from a weeks vacation, I see things are still okay, unless there's a power failure! ARGH!!! Robt Szymanski..
