Molly the goldfish is shown lying in a water solution with a catheter placed in its mouth to keep it alive during the delicate procedure
The emergency procedure saw vets catheterize the goldfish's mouth before anesthetizing Molly (shown here) and remove the mass within 40 minutes
Molly the fish was rushed into the practice after its owners noticed a large lump on its belly
The operation, which cost less than £100, was hailed a success after Molly woke up within minutes of the anaesthetic being stopped and returned home the same day
The smallest animal to go under the knife!
