Goldfish may be kept in an uheated fresh-water aquarium. They are considered ill-suited to live in a heated tropical fish tank, as they are used to the greater amount of oxygen in unheated tanks.
Shrimp and goldfish are not compatible in a freshwater aquarium. Goldfish are known to eat shrimp, so it is not recommended to keep them together in the same tank.
an aquarium or a fish tank
Tropical fish are normally kept in a heated aquarium. Goldfish (and similar species) are usually kept in a coldwater aquarium, or in a goldfish bowl. Where fish are reared commercially for eating: salmon, trout, etc. they are kept in floating fish hatcheries that are usually found in Scottish sea-lochs.
Goldfish are meant to live in cold water, not the warm water in a tropical aquarium. This is a huge reason why goldfish and tropicals shouldn't be in the same tank.
It's not recommended due to the temperature differences (goldfish is a cold water fish and tropical are, well, tropical), also a goldfish will produce a lot more ammonia which it is slightly more able to resist than most tropical species. But over all it is possible.
Yes (I keep fish too :P)
Rule of thumb is to not mix tropical fish and goldfish.
A guppie is a tropical fish and should be kept in an aquarium with other tropical fish, a goldfish is kept in a bowl or tank in cold water - the 2 cannot be kept together because of the different in the temperature of the water

Goldfish and cichlids have different care requirements and temperaments, so they may not live peacefully together in the same aquarium. It is generally not recommended to keep them together.
Goldfish and shrimp are not compatible in a freshwater aquarium. Goldfish are known to eat shrimp, so keeping them together may result in the shrimp being eaten. It is recommended to keep goldfish with other fish species that are similar in size and temperament.
