Monty the goldfish was green around the gills until this op to remove a tumour in his head.
Monty, a beloved five-year-old family pet, had multiple tumours behind its left eye which had spread through its back.
A team of vets from Highcroft Veterinary Group and Bristol Zoo carried out the 45-minute operation, which saw the tiny fish placed in water soluble anaesthetic.
Throughout the £200 operation, it had oxygenated water flushed through its gills and eye.
It went swimmingly and the beloved pet is recovering at home in Bristol.
“He was a brilliant patient and the surgery went very smoothly from start to finish.
“His owners are extremely dedicated and they paid to make sure he had a better quality of life.
“We don’t perform surgery on goldfish very often but we are seeing a definite increase in veterinary treatment in fish generally.
“Monty is doing exceptionally well at home and is acting as if nothing has even happened.”
