Cingulata breeding?

[vyadha]

I have a few cingulata and am thinking about attempting to breed. They are from Greece, 3-4”. Any way of knowing when they are mature enough to breed?

S.cingulata are pretty variable in terms of adult/max size. I know of a confirmed 17cm female, though you're probably already there at 3-4".
