I just traded in my Chilean Rosehair for a White kneed! I'm hoping I'll have a much more interesting Tarantula setup! On one website, It was declared a "Pet Rock" was more interesting than a Chilean Rosehair. After more than six months of having one, I have to agree!!! They are very docile (Chilean), But a pet Moth would be more interesting! Believe me! A live Chilean rosehair is about as good as a plastic replica! The white kneed gets big enough to eat small rats and birds.
