Black symbolizes unconsciousness, unknown and danger. In fact, black is not a color, but a lack of color. Contrary to white, it lacks life and consciousness, and may also mean bad or bad, showing a state.
On the whole, it should be understood that you currently own or will own wealth or resources (fish), but you need to be cautious (black) because there may be problems.
Personal suggestion: If there are investment, purchase and other related activities in the near future, you need to think calmly and not rashly. Caution is the mother of safety. On the whole, it is still very good.
