Key facts

Adult size

10–13 cm

Life expectancy

4–8 years

Origin

Hispaniola (Haiti and the Dominican Republic), from sea level to 700 m; semi-desert, grassland, scrubland, forest edges and gardens. Eight subspecies, paler ones in drier areas, darker ones in more humid areas.

Protection status

Not listed under CITES

Brumation

No winter rest; somewhat cooler in winter with a shorter photoperiod

Cohabitation

Pairs (1.1) are the safest option; never keep males together — they fight until seriously injured. Females also defend their own, smaller territories: a second female is often harassed so much by the dominant one that she eats less and hides. One male with two females only works, if at all, in a considerably larger, densely structured enclosure and only with a spare enclosure ready.

Notes

A grass dweller from dry bushland; it climbs in fine stems.
