who knows. maybe it's sick.
There is a kind of goldfish called the 'Shubunkin' with purple stripes on it but there is no pure purple goldfish species.
The huge puss-spot is probably a tumor, this is found quite commonly in older goldfish.
The most effective goldfish white spot treatment available on the market is a medication called "Ich-X" which is specifically designed to treat white spot disease in goldfish.
"Goldfish" colors range from white to yellow-orange to blue to black. White goldfish have no pigment cells.
nope the purple eyed gold fish has been getting it on behind the yellow eyed gold fishes back
no
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.
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!!!
Actually, goldfish don't have a specific gender. They are born as females, but as they grow, they turn into males.
Some goldfish (Shubunkins) have purple stomachs so it means nothing to me. If however there is something lumpy or festering then please give a more detailed description of the fish and its tank and conditions etc and I may be able to advise you.
A red spot on a goldfish's head could be caused by a bacterial infection, parasitic infestation, or physical injury. It is important to monitor the fish's behavior and consult a veterinarian for proper diagnosis and treatment.
I am unaware of "Black Spot" being a disease of fish. So I would say no.
