This little goldfish suffers from a swim bladder disease; it’s a disease that prevents goldfish from controlling their buoyancy in water. This particular goldfish suffered from it, and it was permanently stuck at the bottom of the tank.
Derek, who works at that particular aquarium took matters into his own hands and built the fish a tiny wheelchair. He used airline tubing and added some valves at the bottom. Derek added equal amount of weight at the bottom and the top, this made it easy for the fish to swim again.
