Rosy Boa Lichanura trivirgata
Rosy boas are small boids, native to California. They seem to adapt well to captivity. While I assume from the literature they are quite a commonly kept snake in the USA, they are uncommon in the UK, and so my experience of these is limited. to the mid Baja variant "saslowi".
By nature a desert snake, rosy boas are (allegedly) among the hardiest of the boids and can tolerate a wide range of temperature conditions, but do seem to prefer the warmer tank.

Rarely exceeding three feet in length rosy boas take well to the captive environment, and thrive in a basic vivarium, taking small mice avidly.

As they are mainly nocturnal hunters, food should theoretically be presented accordingly. In prctice I find them to be good feeders at any time.
Unlike many ground boas, rosy boas are supposed to climb. In the wild they climb cliffs and trees in pursuit of prey.

Certainly my rosies climb.

 

Where some species of boid can have trouble shedding their skins, it's been my experience that rosy boas do not seem to suffer from incomplete sheds. I would guess that this is because incomplete shedding is often related to inadequate humidity, and because sand boas are from dry desert areas, they shed well in very low humidity.

It's been my experience that rosies are gentle easy - to - keep snakes. If I had to suggest a good boa or python for a novice keeper I'd have to suggest a rosy boa. However at a show I met a chap with a rosy firmly bitten onto his hand. This chap said he had never known anything but trouble from a rosy boa!

Remember - every snake is an individual
