Hi there, I have two giant black millipedes. One of them, the female I think is active allmost all of the time. Allways crawling around and exploring. The other one which I think is a male is allmost allways rolled up in a ball. We hardly ever see him moving around but when I pick him up to check on him his legs will move around so I know he is still alive.What could cause this difference in behavior? They live in a 10 gallon tank and have plenty of room.
Thanks
Cindy
