The weather is freezing to death

I don't feel frozen to death. Oriental salamander is not heat-resistant but very cold-resistant. Winter can be normal in winter, and there is no problem indoors. As long as the water in the tank doesn't freeze, it won't freeze to death.

There is also the oriental salamander, which is an amphibian. If the stones in the jar are above the water, they will climb up. Not too deep. It is about seven or eight centimeters deep.

Don't use tap water directly as water. Tap water needs to be dried for several days before it can be used.

What are you feeding the red worm for? This is what my family feeds now. Generally, I soak in water, then take it out of the water and put it in a small spoon. Before putting it in front of them, they will eat it themselves, and throw away the rest directly, so that the food will not always come into contact with water, otherwise it will affect the water quality. Oriental salamanders still have high requirements for water quality. My family used to raise it with mineral water and go into the water. Later, after they used dried tap water, they rarely went into the water.
