Fish in tanks? No, thanks!
Fish are life forms that live in free seas. People have a desire to keep their beautiful seas inside their homes. Then they takes a square or round tank and begins to fill it with beautiful artificial lighting and hard artifacts. Plastic hippocampus, artificial bubble generator, artificial light instead of sunlight, water-current motor that produces water flow, sharp and artificial weeds, and finally feeders that provide a habit-free living environment. It is an artificial, convenient, high-tech living environment in which everything is fully equipped.
But life here is only the fish itself.
