If there are red marks or ulcers on the body this is due to a bacterial infection, most likely caused by dirty water. Torn fins can be due to a condition known as Fin rot disease. U can try treating the water with a Fin rot remedy, and get some anti-bacterial solutions to add to the water. Your pet shop should provide these.
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!!!
Yes the spots are only an indication that the fish is male and in breeding condition.
Goldfish do not get pregnant. They are egg layers. Black spots on goldfish have nothing to do with their breeding condition.
Not a goldfish anymore.

because they are sick dummy
There are diseases such as ich (white spots) which can be treated with salt. They can get to your pet goldfish easily and expert websites will have answers.
It's regalar to have that on a gold fish
If a hematoma has red or purple spots, it could be a bruise or something more serious. It could mean a person is suffering from a disorder or blood problem.
Probably "ick". It needs to be treated.
