Goldfish (Carassius auratus) should not have bubbles on their scales. These could be forming because there is a surfeit of air in the water. Given time this air will dissipate and the bubbles will dissappear.
If you mean like what breed of goldfish you have then that should be fairly easy. I determined what kind I had by looking at his markings and going on wikipedia. If you go to Wikipedia.com and type goldfish in your search bar then scroll down there will be pictures of goldfish with the breed next to them. It is fairly easy and that's how I found out what my goldfish were.
IF you mean literally a goldfish, no. Just no. Otherwise provide information on what you mean by a "goldfish".
You mean 'keeps in the orbit of the sun? Gravitational force of attraction keeps the earth going around the sun.
it means its going to stop working and you should take it to where you bought it from
Nothing. A goldfish is a goldfish, not a gold fish.
It keeps on going; it doesn't stop.
Probably he is busy and can not call you.
Sounds as if your fish is gulping at the surface. If that is so, you need to install an air bubbler. Your fish is running short of oxygen.
Not neccessarilly. You probably need to change its water more often and if possible get a fish tank (aquarium) to put it in. Bowls are not the best containers for goldfish.
Being in the liquid form water keeps on moving on the surface and into the earth due to gravitation force of the Earth.
its your pet
If you mean will a goldfish eat its own fry or eggs then the answer is yes.
