Hi, I'm new to tortoises and I'm wondering which size marginated tortoises should be at certain ages? Mine is about 6 cm long, does anyone know how old he might be? I've had him for about a month (don't actually know if it's a male yet, I just call him a he anyway) and he hasn't really grown since I got him. Is that normal? I'm sorry if there is already a similar thread on this forum, I tried searching for one but did not find exactly what I was looking for.
