Species group: Boas, Anacondas and Pythons
Other common names: Desert Rosy Boa, Coastal Rosy Boa, Mexican Rosy Boa
Scientific name: Lichanura trivirgata
The Rosy Boa differs greatly in lifestyle and appearance from the larger, more “typical” members of its family. Being quite docile, easily bred and modest in size, this fascinating snake is very popular among both novice and experienced reptile enthusiasts. The Rosy Boa’s range extends from southern California and southwestern Arizona, USA to western Baja California and western Sonora, Mexico. Five subspecies have been described. Rosy Boas are found in arid thorn scrub, deserts, and other open, dry habitats.
Appearance / health:
The stoutly-built Rosy Boa ranges from 24 to 40 inches in length. The small dorsal scales appear “polished”, and exhibit a wide range of colors and hues, with blue-gray being perhaps the most common. Many individuals are marked with three stripes of pinkish-orange to reddish-brown, but here too there is much variation. Breeders have established a huge array of color morphs.
This is a hardy species, with captive longevity sometimes exceeding 20 years. As with other snakes hailing from arid habitats, Rosy Boas are susceptible to “blister disease” and other skin infections when kept on damp substrates. The water bowl should be tip-proof and filled to a point where it will not overflow when the snake soaks. Pets kept on sand should be removed at feeding time to prevent digestive tract impactions arising from ingested substrate.
Behavior / temperament:
Rosy Boas are often relatively calm in disposition, and usually tolerate gentle handling.
A single adult may be housed in a 20-30 gallon aquarium. Rosy Boas prefer course sand in which to burrow, but also do fine on aspen and similar substrates. Secretive by nature, they should be provided with caves, half-buried PVC pipes and other shelters. The tank’s screen lid should be secured by cage clips. Ambient temperature: 78-85 F. Basking temperature: 90-95 F.
The jaws of the Rosy Boa are not well-suited to swallowing large meals. Fuzzies and young mice are preferable to adult mice as a food source.
A cooling-off period of 6-8 weeks at 52-54 F will often stimulate reproduction. In some cases, however, normal fluctuations in room temperature will be enough to spur breeding during the warmer months. The 3-6 young are born alive after a gestation period of 4-6 months, and average 10-14 inches in length.

"Rosy was a typical house snake. She hung out in her cage most of the time, but every once in a while, she got out and someone put her in somebody else's clothes. It was funny for us, but for her that was just another day in the life. Eating baby mice and slithering through unsuspecting peoples' undergarments were undoubtedly Rosy's favorite things. Overall she was a very chill snake; she may have constricted an arm every once in a while, but not painfully. Beautiful creature. Feels very weird when slithering over you. Never once bit anyone, and in general liked to hang out with people.."

"I've had one rosy, his name was Pablo. He was a great little guy! These snakes seem to be very docile and would make a good beginner snake. They don't get very big and are easy to handle.<br><br>I really like the rosys because they are a unique snake. They are something different than the average pet snake. They have good appetites and can feed on mice their entire life. Depending on type they average 2-4 ft in size. They are live bearing and are from what I've read and heard easy to breed.<br><br>These little guys, at least my Pablo had a unique personality compared to my other snakes. He seemed almost comical. They come in many different natural colors and there are several morphs as well. <br><br>Rosys are cheap and easy to find. You can get them for as low as $40 if you look hard enough. I would definitely recommend them to someone interested in this species. Their care is very simple and they don't require much room.<br><br>Unfortunately, my Rosy boa passed away. I had a thermostat failure and him along with 4 other snakes passed away. I was devastated and I still feel terrible.<br>."
