Cohabitation
In pairs (one male, one female) is the simplest and least stressful set-up. Because the species often lives in the wild as a small group of one male and several females, a trio (1.2) also works in a larger enclosure – drawback: the females compete for basking and feeding spots, so provide several and keep an eye on them. Never keep two males together.

Notes

Plainly grey-green rather than brilliant — but robust, and one of the easier Phelsuma for getting started.
