- Protection status

- Cohabitation
- Keeping it singly is the least stressful solution, especially outside breeding.

Never keep two males together.
Notes
The nominate form of the former Phelsuma madagascariensis complex (grandis is a species of its own today). Bamboo tubes as a retreat matter. UVB and calcium are essential against MBD. Do not touch it (delicate skin).
