I used to have a huge goldfish tank, and when I was stressed, I would watch them swim and play and socialize. Now I go to the aquarium or the Japanese garden koi pond and watch the fish swim. You can even feed the koi at the pond! There is something about watching fish that seems to be really relaxing. Maybe it's the peaceful water, or how the fish glide around, or the quiet, or all of the above. When I can't go out, I have a lovely video of a coral reef set to some nice instrumental music that I can watch on my computer or TV. Does anyone else find watching fish to be calming?
