Housing. Housing millipedes is relatively inexpensive. A 20lt plastic box or fish tank with a good lid and 2 To 3 inches of compost mixed with leaf litter and rotting wood (no pine as this can be toxic to many animals) should be fine. Millipedes can live communally. The tank should be twice as long, and at least as wide as the individual, or the largest millipede in the tank More decorative displays can be made by including large branches and rocks but live plants should be avoided as they will be eaten. A heat mat at on end of the enclosure should provide enough humidity and warmth for your millipede. Millipedes can be kept in colonies as long as there is enough room for them, height is not as important as floor space! The temperature gradient in the tank should range from 75 to 85° F, and the humidity should be maintained at 75 to 80%
Diet. African giant millipedes will eat a wide range of fruits, veg and rotting leaves. Adults and young alike, eat bananas, tomatoes, melons, romaine lettuce, apples, cucumbers, and other fruits and vegetables. Millipedes should have a supply of calcium and oak/bramble leaves/branches in their diet. A cuttlefish or calcium power should be provided as should a supply of oak leaves and bramble as these assist with exoskeleton growth and replacement and are also necessary for breeding your millipedes.Some other species of millipedes will only eat decaying wood but these tend to be ones for more specialist keepers/entomologists.
