- Cohabitation
- A group of equally sized animals with a surplus of females is the least stressful option: on land, marbled newts are gregarious and share hides. In the breeding season males become rough with each other, so keep more females than males. Never house animals of different sizes together – in the water, smaller newts and larvae get eaten.
Notes
Marbled green, on land outside the spawning season. Keep it cool.
