They are rather hard to take care of when compared to rosies and sand boas?

Some sources i looked at said they wre similar in care requirements. I guess they might wanna alter their information a little bit.

You also said that they will go off food on occaisions. Is this kind of behavior as bad as the ball python reputation?

The main reason i liked rubber boas so much was because of their small size and i wanted a snake that wasnt prone to biting. The rubber boa seemed best for that crtieria bc ive heard sands and rosies get nippy..
