Different types of goldfish can be, such as the Calico Fantail and also different types of koi.
No the koi and the red fantails tails have a difference with the tails, the red fantail is bubbly and the koi is straight so the koi will get more food and will pick on your other red fantails
They get along with goldfish but you'll end up with babies that are part goldfish. I have them in the same pond and that's what happened to me. The main problem with putting Koi with other fish, is sometimes the other fish like to eat Koi.
Fantail fish usually have four mates.

Koi fish can live in almost any country. Koi are thought to be originally from Japan. Many people have outdoor fish ponds in which Koi are the dominant fish.
It depends on what you say on getting along. Sometimes males will fight other males over a female and sometimes they may feel to cramped in their tank. If a fish is chasing another and tearing up the others fins, they may be telling each other they want to spawn.
