A male goldfish developes white spots when he is about to fertilize the females eggs. It could be possible that you have a male and a female! Congrats!!!
The huge puss-spot is probably a tumor, this is found quite commonly in older goldfish.
no
who knows. maybe it's sick.
It is quite possible that the black spot is part of the fishes colouration. Goldfish often have many different colours in many different shapes and shades anywhere on their bodies or fins.
Actually, goldfish don't have a specific gender. They are born as females, but as they grow, they turn into males.
I am unaware of "Black Spot" being a disease of fish. So I would say no.
Yes, you will see a white spot on its gills when it is ready to.
Simply a marking on the fish. Do not worry about normal marks.
get a goldfish and test it out i have a gold fish it dosent really make a difference
Its a very special portal where goldfish climb in to keep you breathing when your asleep
A goldfish.... the difference is hard to spot (especially with modern varieties) you can with a trained eye spot the differences the in ventral fins between male and female, even then it isn't really easy to do without watching the fish spawn (which one lays the eggs)
A few days after spawning you will be able to see what looks like slivers of glass dangling from the water plants and other things in the water. The use of a good magnifying glass will help you spot them.
