there are over 21 different kinds of goldfish species.
Any cold water species that will not be small enough for the goldfish to eat. Unfortunately, there aren't a lot of those, so the best thing to mix with goldfish is more goldfish, if you have enough space. There are many different kinds of goldfish you can mix with each other.
Other cold and fresh water fish.
Goldfish are opportunistic omnivores and will eat plants as well as other kinds of organic matter.
There is over 21 different types of goldfish.
yes they do eat goldfish, Oscars eat all kinds of fish. But not toxic ones.
Goldfish are best with goldfish with the exception of weather (dojo) loaches, bristlenose plecos, or apple/mystery snails
There are many different kinds such as angelfish, goldfish, alge eaters, eels, mini sharks and more but all pet shops are different. Just go to a petshop and you can see what they have.
Aslong as it has enough room and filtration many types of goldfish can be kept together. There are some cases where problems occur as such as the case with Sarassas and Orandas. Sarassas will tend to nibble at the cap of the Oranda causing damage.
Goldfish. They are "feeder" fish for them.
Betta, Goldfish, Minno
No, goldfish are best with goldfish. In addition, tilapia have different needs and are quite likely to be aggressive towards the goldfish.
Different types of goldfish food typically don't affect the colour of goldfish, however there are some specific goldfish foods that may enhance the color of goldfish- but do not change its overall color.
goldfish are not always one color because they have different species. Also, goldfish can change colors over time. They won't always be gold or maybe they won't always be white or whatever color your goldfish is.
You can find them in a grocery store with all of the regular crackers and they are the flavor blasted ones. There are many different kinds of flavored blasted fishy crackers
why are different kinds of plants have different kinds of roots
Goldfish are best with goldfish. A molly and a goldfish have very different needs including the fact that a molly is a tropical fish
Goldfish are best with goldfish with a few exceptions. Dragon fish are saltwater while goldfish are freshwater, thus their needs are vastly different
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.
Yes. Different kinds of salt can make different kinds of crystals
many fish are tiny so there are lots of species of "tiny fish." different types of fish need different foods. bettas need a special betta food, some brands come in fakes. goldfish need goldfish flakes. and tropical fish like tetras, barbs, danios, glofish, guppies and angelfish need tropical fish flakes. piranahs like dead goldfish, so if you have a goldfish and a pirannah and the goldfish dies before the pirranah you could feed the goldfish to the piranah. oher kinds of fish like different things. most fish that live in ponds can get their food by fining it at the bottom of the pond so you don't need to feed them very much. if this doesn't help you should ask somebody who works at a pet store what you should feed your "tiny fish."
Yes they are different variations/varieties of the same species.
No they cannot be in the same tank. Both fish have different needs and are not compatible; goldfish belong with goldfish.
yes in fact i have a normal orange goldfish and a panda at home in my fish bowl
