The fish could barely swim at first.

An employee at Aquarium Designs in San Antonio, TX, went above and beyond to help a goldfish that was having trouble swimming.

Derek Burnett made the fish a sort of wheelchair, Today.com reports.

The Ranchu goldfish had a problem with its swim bladder and would end up in an upside-down position near the bottom of the tank. As a result, the fish had trouble eating.

The fish had arrived at Aquarium Designs via an owner who couldn't look after him anymore.

Today.com reports that the device consists of "some tubing and netting, securing to the fish's body without abrasion by using weights on the bottom and Styrofoam on top to keep him properly positioned."

The story went viral when Taylor Nicole Dean posted photos on Twitter.
