The cause of death of young guppy.

Giant salamander is sensitive, so don't change water often.

It's best to keep two-thirds of the water in the baby's water tank old, so as not to adapt.

It may be the problem of water quality, temperature, toxin and lack of oxygen. . .

Poor water quality will affect the health of fish.

I change the water for the fish once every week or two. Before changing the water, I expose it to the sun and disinfect it. The water temperature after exposure is also suitable for improvement.

When changing water, don't change all the water, suck up the dirty water and keep one third of the old water.

If it is a small water tank, the space is narrow, and the fish should not be too much (to avoid lack of oxygen).

If fish are afraid of lack of oxygen, they can put aquatic plants (there must be sunshine).

If you want to put it indoors in a place where there is no sunshine, you can put the light (you can control the water temperature).

Before feeding the fish, break the fish ingredients first, which makes it easier to swallow.
