So i have two millipedes (propably giant millipedes) but i dont have a clue what kind of specie they might be. They both are about 10 months old and the seller who sold these was sure that they both are same specie even tho their tone of color is visibly different. Any suggestion what these beatiful specie might be? As you can see from pictures the bigger one is way darker even black when the smaller one is more brown(ish)
