Einstein is the fish that can’t swim, so her master made a life jacket for her. Can swim, so her boss made her life jacket. Leighton Naylor, the owner of a fish named Einstein, made a life jacket for his pet after the fish had a disease, which resulted in lost the ability to swim.
During the illness, Einstein turned his stomach upside down and fell to the bottom of his aquarium. It seemed that he was doomed to stay there for the rest of his days, but Naylor came up with how to help the fish: he used to create a life jacket waste tubes from droppers — so Einstein again gained the ability to swim in the aquarium and not to fall to the bottom.
