Question

Answer
Hi Leila,

It's virtually impossible to sex Goldfish as the differences are subtle even when they are in breeding season.

Males tend to have mating tubercules on the head and gill covers. However, they are difficult to see and its unlikely that you'll gain a solid knowledge of whether they are male or female.
