New snakes and new terrarium

[afore01a]

Goodmorning everyone.

In October I will have 1.2 Thamnophis sirtalis infernalis born in may. Do you thing I can keep them together in a terrarium 45cm x 45 cm?

Thanks in advance for the advice.

18in x 18in, seems a bit small to me. So they will be 5 months old in Oct?

Thank you Steve. Yes, they will be 5 months old. What size counsel for the terrarium?
