Elongated enclosure size

[bkk]

I live in Thailand so the climate is perfect for these tortoises. I would like to know the size needed for there new enclosure. I am planning on buying 5. The ratio is 1:4 male to female. I will buy them as adult size so they can be ready to breed. I have read that you need a rather big enclosure if you want to keep the male and females together especially if it's more then a pair because the males can be aggressive towards females. Do you guys have any idea of how big the enclosure has to be?

Thank you,

I think you need a yard...one adult size about 30cm

I would guess that for five of them it would need to be at the very least 20' square. Almost 7 meters square. With lots of hides and shady plants.
Bigger yet would be better. (It can't be too big.)
