I'v had 3 giant african Millipedes for almost a year now. my oldest one has no grown an inch since I bought him(or her). To add to my aggrevation, I'v noticed that he is missing some legs on segments close to his head. They look like they've been chewed off almost but I cant believe it would be him doing it to himself or one of his tankmates. I keep their tank clean and moist and give them a variety of fruits and veggies supplimented with calcium powder. Any information or guesses on to why this is happening would be much appriciated. He still moves around like he has all his legs, its just unsettling for me to see it.
