They say that you can look at three things forever, but what about the chaotic movement of fish in an aquarium? This may have a relaxing effect and that's all. A static picture, in my opinion, is more conducive to calming and peace. It's more pleasant to "think about things" at such a moment.
And here it is – beautiful! Aesthetic pleasure and childish excitement at times. But more and more “fish” makes me hungry in the literal sense of the word, as it is perceived as food. 😬
The guys in the fifth video impressed me. There is even an instructor there! This is a fitness aka aerobic gym. I told you that we are in an aquarium for them, and the guys live their full lives, so they do sports.
It would be great to swim next to such nimble and beautiful ones somewhere in the wild.
