I like raising pedelings to adults because I can see them grow and develop into killing machines :). Raising pedelings isn't very difficult and I will tell you how to do it.

House the pedeling in a small container. This has two advantages. The first is you can keep many in a small area and second they will find their food more easily then in a big container. The most important thing with raising pedelings is to keep the substrate moist. Pedelings are very sensitive for dehydration. Make sure to keep the humidity up and the substrate moist (not wet). If you want to be absolutely sure the pedeling has access to water place a small waterdish (bottle cap) in the container.

I give dead prey the first time I feed the pedelings. After they have eaten I give them immobile/harmless prey for a couple of weeks. You can crush the head of a small cricket/roach with a pair of tweezers. That way the prey cannot harm the pedeling. After a couple of weeks the pedelings get live prey. It's fun to watch them hunt. I feed the pedelings once a week 2 crickets/roaches. This is enough for a pedeling to be remain healthy and grow.

Depending on size it takes 1 to 4 years for a pedeling to reach maturity. One last thing, I keep all my centipedes (pedelings and adults) at room temperature 20 - 22 celsius during the day and 17 - 19 celsius at night. You can use extra heating to speed up to growing process but i don't think it is necessary.

The 2 pics above and below show the colour differences between pedeling and adult. I use this pics to show you the long way a pedeling has to go to get adult and it shows that it is almost impossible to identify a pedeling if you don't know which specie it is.
