Einstein the goldfish, who had lost the ability to swim, is afloat once more after his owner in England made him a special buoyant frame. Einstein developed swim bladder disease, which caused him to turn upside down and sink to the bottom of his tank. His owner was so distressed by the sight of his struggling pet, he knew he had to take matters into his own hands. He made Einstein a "floating frame" from recycled tubing, which fits perfectly over the fish's two-inch long body.
