Keeping it singly is least stressful and safest for this large gecko that bites. A pair (1.1) only in a considerably larger enclosure with several hides; drawback: the female is harassed and bite injuries are possible. Never keep two males together.

Notes

A close relative of the tokay, a little slimmer and quieter. A powerful bite – move it only in a container. Very loud calls at night.
