A goldfish can make a good starter fish, but more realistically they are just as hard to keep as any other type of fish. They get the label of being "Hardy" fish because they can tollerate poor water quality conditions for a little longer than most fish. This is the only reason why goldfish are recommended for beginners. The dangerous thing about a novice fish-owner owning a goldfish is that goldfish will constantly beg for food which often causes the owner to overfeed them resulting in the fish's death. A better fish for beginners would be a Betta fish (betta Splendid).
Common goldfish or goldfish.
NO
Good good
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.
Mosquito fish are not Goldfish. They are tropical livebearers. They may eat the goldfish food but it is not the right food for them and so will not be good for them.
A gold fish or a beta fish should be a good starter fish.
Just about any fresh water fish. If they are smaller than the other fish they will be eaten if they can't hide in rocks or something. I had goldfish and mosquto fish in an outdoor pond and it worked.
a small goldfish or any type of small fish
yes i have a guppie and 3 goldfish in the same tank :)
The best thing to do is ask the shopkeeper in the fish shop and find out first but goldfish go together with no problems if you are lucky because some goldfish can't live together. http://en.wikipedia.org/wiki/Goldfish
Goldfish are pretty easy to keep.
a goldfish is a feeder fish. I kind of disagree with the answer above. Yes, goldfish CAN be feeder fish, but they aren't necessarily feeder fish. Feeder fish are really fish that are rather small and are fed to other animals, and that are for some reason thought as not being as precious as other "pet" fish. So a feeder fish and a pet fish are two different kinds of fish, really. Not all goldfish are feeder fish. There are expensive goldfish, more than 10 dollars per fish! Then there are those goldfish breeded to be eaten that are sold as 75 cents per fish. So there are "pet" goldfish and "feeder" goldfish. So, a goldfish is not necessarily a feeder fish.
