We've all see the adorable animal wheelchairs that help cute little dogs and sweet little turtles regain their mobility. We've found the goldfish version of that device, what we call a "goldfish wheelchair". This ingenious device was designed to help a sick goldfish swim upright and stay afloat.Fish who are recovering from swim bladder infection have a difficult time swimming upright on their own. Those who know about these things will tell you that green peas are the solution to buoyancy issues as a result of constipation. Infected swim bladders require a bit more inventive solutions.
