How long do Rosy Boas live?
Rosy boas are long-lived at 20-30 years and reach 2-4 feet (60-120 cm), with females usually larger; adults weigh 300-800 grams.
What do Rosy Boas eat?
They eat frozen-thawed mice: pinkies for babies, adult mice for large females. Feed juveniles every 7-10 days and adults every 10-14 days, one prey item no wider than the thickest part of the body. Never feed live prey; no insects, eggs or plants.
Rosy Boa enclosure setup
An adult needs at least a 20-gallon long terrarium with a sandy-aspen substrate for burrowing. Provide a warm side of 85-90°F (29-32°C) and a cool side of 72-75°F (22-24°C); nights drop to 68°F (20°C). Keep overall humidity low at 40-50% but include a humid hide (damp moss) for sheds. UVB is optional. A secure lid is required.
Common mistakes with Rosy Boas
Usual errors: too much humidity (scale rot), live feeding (injuries), overheating the whole tank (they need a gradient), and cohabiting (stress and cannibalism risk).
Beginner mistakes to avoid
- Humidity too high — scale rot and respiratory issues.
- Feeding live prey — rodent bites cause serious wounds.
- No temperature gradient — constant high heat stresses them.
- Cohabiting — risk of stress and cannibalism.
