A goldfish has been a one-of-a-kind floating wheelchair.
Why? ….. Because he has an incurable disease which meant that it was stuck at the bottom of it’s tank.
Water treatments and adjustments to the fish’s diet were unsuccessful in treating the disease, so an aquarium worker engineered the “wheelchair”.
It’s made of airline tubing that is placed around the goldfish. Some weights were added to bottom of it, so it then acts like a chair to prop him up.
This “wheelchair” now makes it easy for him to swim around.
