fish tank. You can choose some strange stones to increase the mystery, and you can also put some jade to make the fish tank more valuable, especially with the goldfish, which looks very elegant. It should be noted that too many stones should not be placed, otherwise they will take up a lot of space, which will affect the activities of fish. In addition, the stone should not be too sharp, if the fish touches it, it may hurt it, causing its scales to fall off.
should be installed in the tank? 1. Filter: Generally, a filter should be installed in the fish tank. Filtration can better maintain the water quality. Usually, the water may need to be changed once a week. With the filter, it is no problem to change it once a half month. Moreover, the filtered water is more beneficial to the growth of fish, avoiding the aging of water quality and increasing dissolved oxygen.
2. Oxygen pump: Although some filtration equipment can also increase the oxygen content of the water body, the effect is not very good, especially if you raise some large fish, you still need a special oxygen pump. The oxygen pump is usually turned on 24 hours a day, and if the fish's demand for oxygen is not high, it can be turned on intermittently.
3. Lamps and lanterns: The fish tank still needs light, but if it receives sunlight directly, it will easily lead to the outbreak of algae in the tank, so it needs special aquarium lights, which should be turned on for 6-8 hours every day, not at night, so as not to affect the rest of the fish. Proper lighting is good for fish hair color, but also good for their health.
