in the open-air fish tank? It's better to move the open-air fish tank to a warm place indoors. If it's inconvenient to move or it can't be opened indoors, you need to use other ways to keep warm. It can be buried in the soil, but not all, half of it can be buried, and the exposed half can be wrapped with quilts, so as to avoid freezing and affect the health of the fish in the tank.
of open-air fish tanks? 1. High dissolved oxygen: The biggest advantage of open-air fish tanks is sufficient dissolved oxygen, because it is different from closed fish tanks at home, there is no top cover, so air can enter the water body, thus ensuring the oxygen content. High dissolved oxygen not only helps fish breathe, but also better maintains water quality.
2. Sufficient illumination: Since it is an open-air fish tank, the illumination must be sufficient. Light is good and bad for water quality, on the one hand, it is good for the health of fish, but also can promote its hair color. On the other hand, it will also allow a large number of microorganisms in the water, including algae, so it should be properly controlled.
3. Plant aquatic plants: Although ordinary fish tanks can also plant aquatic plants, open-air fish tanks can choose more aquatic plants, such as some emergent plants can also be planted in the tank, such as lotus, cattail, canna and so on.
