Cohabitation
Keep in pairs or as a harem: one male with several females works, since females generally tolerate each other but each need their own basking and hiding spots; feed separately if there is a size difference. Several males, however, do not get along — they fight over territory and basking spots until one is injured or permanently pushed into a corner.

Notes

Skittish and fond of running — it needs a large, solidly furnished terrarium with a big water and bathing area (it likes to swim and dive).
