Watching A Fish Tank

He just placed his elbows on the small wooden table. With both hands placed on his cheeks, in a pause that seems like he was pausing for a painter to draw a new sculpture. He was looking at this fish tank. There are many of them in that small tank and they all look the same.

He kept watching their movement for a while, and he started wandering, if they are watching him back. Or, if there conscious has realized that he is on the outside. The room was too quiet for him to keep thinking. He thought, all creatures share the survival instinct. But, what level of conscious do they have? He thought that, we are unique because, of our awareness that life is a journey with an ending. He thought, what if he took one fish out of the tank? It may not be noticeable, especially in the perspective of, their species lifetime from existence till now. Then he stopped for a moment, to realize that it might be similar to any other living.
