Cohabitation
Keeping a group of similarly sized animals of the same species works well, as they are not aggressive towards each other. Only combine animals with a maximum size difference of about 25%, otherwise smaller ones get eaten or attacked; provide enough hiding places so each animal can retreat. Do not keep fish or larger invertebrate tankmates, since palmate newts hunt them and are themselves nipped by some fish.

Notes

Cool conditions are needed, and summer overheating must be avoided. A native, protected species: lawful only as a captive-bred animal with proof of origin.
