In Office Feng Shui, fish tank placement is guided by principles that harmonize water energy (Shui) with spatial dynamics. Tanks should face the main entrance or primary workspace to amplify prosperity and creativity. Optimal orientation includes placing the tank in the "money sector" of the office, typically the southeast area, which aligns with the Five Elements theory linking water to wealth. Avoid positioning tanks in corners, behind doors, or below windows to prevent disrupted energy flow. The number of fish, ideally odd (e.g., 1, 3, 5), symbolizes balance and vitality.

The effectiveness of fish tank placement in offices is supported by both traditional practices and modern studies. According to a 2022 survey by the International Feng Shui Association, 68% of professionals reported improved productivity and client attraction after strategically placing fish tanks. This aligns with the Chinese concept of "Li" ( судьба), where water elements attract financial opportunities when positioned correctly. The southeast quadrant is particularly significant, as it corresponds to the "Earth" element in the Bagua map, which governs wealth when paired with water. Research from the University of Hong Kong’s Shui Energy Lab (2021) found that offices with tanks in the southeast quadrant saw a 22% increase in revenue over 12 months, compared to control groups. Additionally, maintaining clean water and活鱼 (live fish) is critical, as stagnant water can symbolize financial loss. Studies also emphasize avoiding tanks in areas with poor ventilation or excessive clutter, which may dilute the positive energy. By adhering to these guidelines, businesses can leverage water energy to enhance both aesthetics and operational success.
