He fashioned the custom set of braces in a surgery that cost only $150

An adorable goldfish is now eating and breathing normally thanks to a crafty veterinarian - and a credit card.

Mr Hot Wing was born without a lower jawbone, making it nearly impossible for his mouth to stay open.

That's when Dr Brian Palmeiro from Lehigh Valley Veterinary Dermatology in Allenstown, Pennsylvania, stepped in.

Palmeiro, better known as the Fish Doctor, fashioned a custom set of braces that would allow Mr Hot Wing's mouth to stay open.

But don't call him a metal mouth. Mr Hot Wing's braces were actually fashioned from a plastic credit card.

And while a set of children's braces can cost anywhere from $3,000 to $7,000, Mr Hot Chip's set is hardly breaking the bank at only $150, according to 6 ABC.

This isn't the first time Palmeiro used a credit card to help one of his fishy patients.

In November the fish doctor fashioned a sling out of an old plastic card to help Alice the pleco and her dislocated right pectoral fin.

Just two days later her fin was back in place and Alice was swimming in her favorite tunnel once again.
