History and origin
Native to North America. A small, active snake.
Temperament and character

Living together
Children: depends on species + educational handling. **Other pets:** avoid — risk goes both ways. **Other reptiles:** depending on species, separate terrariums are best.
Life stages of the Serpiente Jarretera
Each stage has its own care priorities. Life expectancy: 8-12 años.
Neonate
0-3 months
Born live and very active; secure enclosure, 22-28 °C gradient, water area; small pieces of fish/worm and thiaminase-free fish.
Juvenile
3-12 months
Varied diet (fish, worms, safe amphibians); avoid fish with thiaminase; feed 2-3 times a week.
Subadult
1-2 years
Terrarium with plenty of water and a dry area; warm spot 28-30 °C; monitor sheds; supplement B1 if frozen fish is given.
Adult
2-12 years
22-28 °C gradient, no mandatory UVB; feed 1-2 times a week; keep the temperature stable (sensitive to hypothermia).
Care
Terrarium: minimum size depending on species (check species-specific guides). UVB essential for diurnal species.
Temperature: day/night gradient · warm zone vs cool zone for thermoregulation.
Humidity: depending on species (rainforest 70%+ · desert 30-50%).
Feeding: species-specific diet · insectivores, herbivores and carnivores vary radically.
Vet: exotics vet (a regular vet WON'T do). Annual check-up.
