I have a 3000L pond in my garden and the dozed or so comets I put in several years ago now number 50. Generally they look great with flowing tails and a range of colour, but the larger ones have hemisherical lumps the size of half a small pea. The fish seem well and I only feed once a week. Is there a goldie out there who knows what this might be and how I should best treat it?
Cheers,
Greg
 
Do you have pictures of this? Pictures are always extremely important especially in cases where things like this don't often happen or are out of the norm. What are your water parameters as well? What do you feed your fish?
