Origin

Nicaragua (Central America) – the common boa (BCI)

Protection status

CITES Appendix II / EU Regulation Annex B; B. c. imperator is listed in Annex 5 of the BArtSchV -> exempt from the registration requirement since 2005, but proof of origin is mandatory.

Brumation

No real winter rest; a slight cooling period to stimulate breeding is possible

Cohabitation

Keep them singly – a loner; only for supervised breeding. Even where group keeping works, the feeding accident remains the risk: always feed them singly, ideally in separate boxes, and only house animals of roughly the same size together.

Notes

The Nicaraguan boa (BCI) – it tends to stay smaller than other localities and is often boldly coloured, which makes it popular with keepers who have less space. Robust; obesity through overfeeding is the commonest mistake. Localities in the trade are often not pure.
