Goldfish should live with goldfish with the exception of weather (dojo) loaches, bristlenose plecos, or apple/mystery snails.
Another goldfish, try not to put slow fish (fantails) and faster fish in the same place because the faster fish will steal all their food. But you cant really chose what companion will be the best because all goldfish have certain types of personalities and they will either love eachother or hate.
The best and only good tank mate for fancy goldfish, are other fancy goldfish.
Other goldfish, preferably This will ensure that the goldfish will not be injured by other tankmates and also ensures that the other tankmate's gills are not damaged by the large amounts of toxic wastes (ammonia) that the goldfish produces daily.
Goldfish get along with many types of peaceful freshwater fish; basically anything that won't eat them. However, goldfish should not be kept with most of the fish you find in a pet store, because they are coldwater fish, and require a lower temperature than most fish.

Not always. Goldfish are largely peaceful, but... They have ravenous appetites and eat aggressively, so tankmates may not get enough food and/or may get hurt in the process. They foul a tank with copious amounts of waste (poop), so tankmates may not be able to survive the more toxic environment. They get big, so tankmates and decorations may get broken or injured. All of these conditions can be mitigated with planning and proper care and you can enjoy your goldfish for years and years (they can live up to 25 years with a reported world record of 41).
Yes! Because they are both livebearers, they are great tankmates for each other and can happily live in the same tank. Other good compatible tankmates would be swordtails and guppies, which are also livebearers. Livebearers tend to stick together and can be the perfect set up for a community aquarium.
