Cohabitation
Single housing is safest. Keeping a pair (1,1) or one male with two females (1,2) is also possible given enough space, climbing opportunities and several hiding spots - the key is only one male per enclosure. Two males do not get along: they fight over territory and basking spots until one is permanently displaced and feeds poorly, without any visible injury.

Notes

Strictly arboreal: a tall, densely planted terrarium and UVB are needed. Shy and quick, not an animal for handling; high humidity prevents shedding problems.
