You can't put tropical fish with each other or they will eat eachother
who cares? I think they will eat them because i once had two little guppies and the next morning they were gone. Answer- Yes, they will eat them. If they don't the guppies will die, because the stuff on the goldfish is like a poison for other fish. You should only put goldfish with 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.
it depends on how big it is if it is a goldfish or beta it can be in a bowl.If it is one of those big tiger fish or aqarium fish then put it in a big tank. A fish will grow to the size of the tank or bowl. For instance, say a goldfish is in a tank, it will not grow as big as the tank; however it will grow big enough to be able to swim in their environment. The fish will not overgrow the tank. I had a six inch goldfish in a thirty gallon tank.
Any fish that eat other fish would eat a gold fish. Yet since a gold fish is a house pet err fish it would die at the shock of being put in other waters. A baby gold fish may be eaten by other domestic fish also. A good rule of thumb is that if a fish's mouth is big enough to eat another fish it would be unwise to put them together. Specifically relating to goldfish, though, remember that they are often used as feeders.
Betta fish are best as a solitary fish and are not compatible with goldfish.
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.
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.
You need to provide 1 gallon of water per inch of fish. Goldfish get along fine with other goldfish.
If the goldfish is big enough and the guppies small enough, yes the guppies could well be eaten by the goldfish. Also, guppies should never be with guppies are guppies are tropical fish and goldfish are coldwater fish.
