I want to put a fish tank in the dining room. The dining room lacks light. Is it suitable from the perspective of geomantic omen?

The poor light in the dining room can be changed by the following methods:

1. Stick a picture of a sunflower when it blooms, which means "it's easy to see flowers and trees in the sun for spring". Can make up for the defects in lighting.

2 A dimly lit dining room should have fluorescent lamps on the ceiling. Some places that lack sunlight are dim and lifeless day and night, and it is easy to feel depressed if they stay there for a long time. If there is such a situation, it is best to hide fluorescent lamps in the wooden troughs on the four sides of the ceiling class to make up for it. The light emitted from the ceiling is not dazzling, while the light emitted by fluorescent lamps is close to sunlight, which is most suitable for places lacking natural light, and fluorescent lamps and crystal lamps can go hand in hand. Fluorescent lamps are used for lighting during the day and resplendent crystal lamps are lit at night.

3 The colors of the dining room are mainly warm and light.
