It is suggested that the goldfish bowl should be placed in the living room or between the living room and the gate, because the living room is an important place for gas collection in the house, and the gate is the air inlet of the house, so the gas between the two is the most prosperous. Putting the goldfish bowl in this position will be of great help to the goldfish and the geomantic omen of the house.
The dissolved oxygen in natural water is relatively high, which refers to rivers, lakes and seas, and can reach 8-12 mg/L. However, in the case of artificial feeding, the opening surfaces of fish ponds and fish boxes are small, the light is limited, and the feeding density is relatively high, so it is necessary to install an air pump to inflate and increase dissolved oxygen.
Extended data:
The feeding of goldfish is introduced as follows:
If the density of fish farming is low, the aerator can be operated for about 8 hours every day. If the density is high, it will be open 24 hours a day. In addition to oxygen, there is another condition: illumination, which is of great significance to the transformation of water quality and the growth of aquatic plants. Ultraviolet rays in sunlight also have bactericidal effect.
Therefore, light can be used to supplement the indoor water tank that lacks light, and ultraviolet lamps can be installed for several hours every day to supplement the lack of sunlight. Swimming too much goldfish will generally make the body longer, the abdomen flatter, the tail shorter and thinner, and the head features degenerate and become sharper. The water for keeping goldfish is light green with a small amount of phytoplankton, which is beneficial to the bright colors of goldfish, which is very important.
