Cecilia, this is the place for anything not related to cornsnakes, so yes!!
I have had rosy boas (I still have 4 elderly ones), and I as much as I love them I love my corns much much more. The corns are more colorful, bigger and easier to keep. But no matter what you get, please consider buying from a GOOD breeder instead of going to a petshop.
I'm just of the opinion that a person who dedicates so much of their time and money to a species that they are passionate about deserve more support than a pet shop.
