Hamartoma in a goldfish

This fish developed a large irregular mass at the top of the opening to the gill cavity. It had become enormous and was causing problems with its swimming. The fish was given an anaesthetic and removed from the water for examination and successful surgical removal. There was no regrowth of the mass, which laboratory tests suggested was a hamartoma. These are uncommon and generally considered as non-cancerous abnormal growths.
