A pet fish in the UK has undergone an hour long operation to remove the tumor, which costs about 400 pounds, while the pet fish is worth only 2 pounds, the report said on July 23.
The 9-cm-long goldfish is 2 years old and has a tumor on its head. Doctors have removed the tumor after anesthesia to prevent it from deteriorating and dying. The owner of the goldfish is a cardiology nurse, who was also involved in the operation. She said: 'the tumor is growing on his head, and if we don't do something about it, it's bound to die. '
