The tumor was removed successfully and the patient is doing swimmingly - appropriately for a goldfish.

Sharkie had been laboring along for about 18 months with a tumor growing near his head when veterinarian Charles Coleman was called for a consult with fish, actually a miniature carp. Goldfish are members of the carp family.The fish weighed about a pound, but about 15 percent of that was "a translucent, creepy material" that made it a struggle for Sharkie to stay upright, said Don Rokkan, whose 11-year-old daughter, Lainey, owns the fish.
