Yes a ryunkin is freshwater. All types of goldfish are freshwater regardless of being a singletail, or fancy type
Some common breeds of goldfish are: the Black Moor goldfish, the Ryunkin goldfish, the comet goldfish, the common goldfish, the Calico Fantail goldfish, the telescope eye goldfish, the bubble eye goldfish, the pearl scale goldfish and the Oranda goldfish.

The fresh water part .... Goldfish apparently come from Asia, however they don't live in the ocean because goldfish are fresh water fish.
There are both saltwater and fresh water goldfish so it doesnt really matter which. Saltwater ones can't live in fresh water and vice versa.
A goldfish.

fresh water fish
Yes

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.
possibly because brackish is a mixture of fresh and salt water and goldfish cant live in salt water so yeah most likely.
