Most of the types of salamanders prefer cool, damp surroundings. However, they are cold blooded animals. Hence, maintaining optimum temperatures is very important for their health. In case you are keeping tiger salamanders in your house, the temperature of the terrarium should be maintained between 65 - 70 °F. For fire salamanders, the temperature should never cross 68 °F.
Salamanders are not fussy eaters. Both, tiger and fire salamanders have a healthy appetite. They are carnivores. In the wild, their food is quite varied. In captivity, you can feed them pillbugs, beetles, earthworms, woodlice, slugs, small moths, crickets, and meal worms. On the other hand, if you are keeping aquatic salamanders, you can feed them water invertebrates such as water fleas, brine shrimp, and Daphnia.
Though they do make good pets, salamanders are not the petting kinds. It is not that they will snap and bite, but they have delicate and sensitive skin. Oils and salts from your hands may contaminate their skin and cause infections. Also, some types secrete certain toxins that may cause skin irritation. Use a fish net to handle them.
