Epicrates maurus
The smallest rainbow boa, ranging from southern Central America into northern South America. Dark-edged rings with pale centres mark a uniform brown ground, and the scales shimmer iridescent in sunlight. At night the animal pales to an almost silver tone.
Epicrates maurus is a non-venomous boid ranging from southern Central America through Trinidad and Tobago into northern South America, and is the smallest of the rainbow boas. It averages 90-150 cm, while E. m. colombianus, the subspecies that dominates the trade, reaches 150-180 cm and matures at four to six years. Females are clearly larger than males. The ground colour is a uniform brown with dark-edged rings whose pale centres form saddles, and in sunlight the scales shimmer with the iridescence that gives the group its name. Through metachrosis the animal changes colour between day and night, paling to an almost silver tone after dark. It is semi-arboreal, climbing trees and shrubs as a juvenile to forage and avoid predators but becoming largely terrestrial with age. It is nocturnal and most active in the middle of the night. In captivity it is extremely sensitive to temperatures above 32 C, so a thermostat is essential. It tolerates lower humidity and cooler nights than its relatives, which makes it the easier rainbow boa to keep.

Listed in CITES Appendix II as Boidae spp. since February 4, 1977 (Species+). As an Appendix II species, registration certificates for international rare wildlife are not required. Among boid snakes designated as designated animals in the Animal Protection and Management Act Enforcement Order, only two species—boa constrictors and green anacondas—are regulated, and this species does not qualify.

It is extremely sensitive to anything above 32 C, so use a thermostat. Build a gradient with a cool side at 21 C, a warm side at 28-29 C and an ambient of 26-27 C. It manages at around 50% humidity, tolerating drier air than its relatives.
Semi-arboreal, so give it height as well as floor area: full length by half length for the footprint and at least 90 cm of height. Fix cork bark and branches firmly to the walls or floor, and add hides plus a water container it can soak in.
Feed frozen-thawed mice and rats. A meal of roughly 10% of body weight is the guide, and no prey item should be wider than the snake at its thickest. Feed juveniles every one to two weeks and adults less often.
Nocturnal and most active in the middle of the night. Juveniles climb readily and adults become more terrestrial. Keep it singly, and use feeding tongs to avoid accidental bites.
Dehydration and overheating are the two leading causes of death in rainbow boas. Incomplete sheds, dry wrinkled scales and regurgitation signal dehydration. It is a boid and therefore on CITES Appendix II, and it is not one of Japan's designated dangerous animals.
Intermediate. This is an intermediate-level species. Some prior experience and knowledge of environmental management are recommended.
The ideal temperature for Colombian Rainbow Boa is 21〜29℃. Recommended humidity is 50〜70%. Avoid sudden temperature changes and maintain a stable environment.
