— People love their pets, but how far would you go to save a goldfish?

Veterinarians at North Carolina State University are delivering life-saving treatment, including cancer treatment and even surgery, to some finned pets.

"I don't really think twice about it," fish vet Dr. Greg Lewbart said Monday. "I just think, this is Teddy or this is Lucky or Tulip or Bubbles, and they're a part of the family, and I am going to do my best to help that animal and the owner."

Lewbart said N.C. State handles about 50 fish cases a year, from CAT scans to chemo to operations. He even makes house calls, noting that it's easier than transporting a fish in a car.

The equipment used for fish surgery isn't high-tech; it's basically a container and a hose that continuously pumps water into the fish.

"They can live out of water as long as you keep their lungs moist or irrigated," Lewbart said.

Pat Gupton has taken her goldfish and koi to Lewbart for years.

"I've had some of these fish for over 30 years," Gupton said. "Once you get to know them, they have such distinct personalities."

She said she doesn't hesitate to seek treatment for her fish.

"Your fish gets sick, are you just going to let it die? No, no no. You are going to take it to the vet school," she said.

The care isn't without expense. A basic exam can cost about $200, while surgery can cost thousands of dollars.

"We've certainly had owners spend $1,000 to $2,000 on a pet goldfish," Lewbart said. "There is a real bond that people form with their pet fish – not everybody, but a lot of people do."

Gupton couldn't estimate how much she has spent on keeping her fish healthy over the years. The joy of watching them makes whatever the cost worth it, she said.

"I will go without to have my fish have what they need," she said. "If you have an animal, whether it is a dog, a cat or a fish, you have to take care of it. It is your responsibility."
