That is what Ryunkin Goldfish look like. If however, the fishes scales are sticking out like a file or rasp, the fish is suffering from a fatal disease called Dropsy. There is no known reliable cure for Dropsy. There are expensive medications available at pet shops that make the claim to cure Dropsy but in my experience they do not work.
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.

Most likely not. If there are goldfish, then there are definetely going to be predators. Goldfish are small, and one predator could eat about 5 goldfish. It's very unlikely, but possible.
Your goldfish are all going to die. Sorry to be so blunt about this but goldfish NEED at LEAST 1 gallon of water per one inch of fish. They should be kept in large aquaria or ponds. They are not suited for life in a bowl.
