Newt has strong vitality, especially excellent self-healing ability, so it is sometimes found that when an individual has a limb broken due to mechanical trauma, it will not take long for a granulation to grow from the wound and gradually develop and repair to its original state. Clean pool water is better to feed, and well water is also suitable. If tap water is used, it can only be used after 3-5 days, otherwise the chlorine in tap water will lead to the death of salamanders. Changing water is a routine management work. Keeping the water fresh and clean is beneficial to the normal life of salamanders. Change water every 2-3 weeks in winter and every 3-5 days in other seasons.

Newts like to eat live animals. Water earthworm is an ideal feed, just put a little every other day; Earthworms can also be wrapped in a single layer of gauze and hung in water with a rope. Earthworms will stretch out part of their bodies through the gaps in the gauze, and salamanders will swim to pull food. In addition, there are tadpoles, dragonflies, water fleas and so on. It is also the favorite food of salamanders. In the absence of small animals, lean pork can also be cut into small pieces for feeding. But be careful not to eat too much, and it is advisable to have no leftovers to prevent food from rotting and affecting water quality.
