No, goldfish are best with goldfish with the exception of weather (dojo) loaches, bristlenose plecos, and apple/mystery snails.
Although goldfish can survive in warmer water temperatures, they are a "cold water" fish and not a tropical fish.

Rule of thumb is to not mix tropical fish and goldfish.
No, Neon Tetras and Goldfish do not belong in the same tank. Goldfish prefer cold water, while Tetras are more of a tropical fish.
No goldfish would prefer to have a lower temperature than any type of tropical fish, however some goldfish can withstand higher temperature if they are slowly acclimated to it! But in the long run goldfish would be happy with other goldfish and tropical fish with tropical fish... there is a reason you don't see the goldfish with the tropical fish in a good aquatic store.
The goldfish should never be in the same tank as guppies. Goldfish are coldwater fish and need to be kept below 70F. Guppies are tropical fish and need to be kept above 70F.
None, goldfish are cold water fish, so having a tropical fish as a tank-mate just wouldn't work because tropical fish need to live in warm water.
I think that the shark would eat the goldfish probably. I suggest don't try it.
Only if it has a heater in the tank other wise the tropical fish will die. They are warm blooded instead of cold blooded.
They should never be in the same tank because Guppies are tropical fish and like to be kept over 70F and Goldfish are coldwater fish and like to be kept below 70F. So Goldfish should not bite guppies because they should never be in the same tank together...
Goldfish, even though they are technically cold-water fish, can do fine at tropical temps. Be careful though, even the smallest species of goldfish you can commonly find needs 10 gallons all to themselves, because they get really big.
Well, the correct answer is no. But when I kept my tank at room temperature, I had no problems.
Angel fish are semi aggressive fish. They may have a tendancy to pick on the gold fish. Also, angelfish need tropical warm water to survive. Gold fish like cold water. I would not put them together. If the Angel is big enough it will eat your goldfish.
you should'nt put parrotfish with goldfish. Parrot fish are known to be be quite mean. It will eat or kill the goldfish if it is smaller than he is. So unless you have a really big goldfish, I suggest not putting it in with the parrotfish.
