Dreams about fish often symbolize emotions, intuition, and personal growth. In your dream, the alive but frozen fish might represent feelings or aspects of yourself that are currently dormant or constrained. The fact that you knew they were alive suggests an awareness of your potential or emotions that are not being fully expressed.

Pouring water onto their tanks signifies your desire to nurture and revive these feelings or aspects of yourself. Water is often associated with emotions and healing, indicating that you are taking steps to facilitate your emotional growth or to bring certain feelings to the surface.

This dream could be encouraging you to explore and express your emotions more freely, especially after your retreat experience. Consider reflecting on what areas of your life may feel stagnant and how you can nurture them. It's a positive indication that you have the power to bring these parts of yourself back to life and movement.
