Female Colombian boas can reach a length of 10 feet, although most grow to no more than 8 feet in length. Males are smaller and typically reach a length between 5 and 7 feet. Central American varieties grow smaller but are less likely to be docile due to breeding.
Specialized reptile housings are ideal for the Colombian boa, as they are tailored to maintain proper humidity levels. Aquariums and other enclosures may be used but are less preferred. While a larger space is necessary for adult boas, young ones are more comfortable and feel more secure in smaller areas. As with other reptiles, heat sources must be placed on one side of the environment, creating a cool side and a warm side.
