gold fish flakes
Wild Goldfish are found in the Yangtze river, but are very different from the domesticated goldfish. In the wild, goldfish can grow up to five feet long, and are reputed to live for hundreds of years.
No - they would never eat them in the wild - so why feed them in captivity !
Goldfish do not populate any rivers. This because goldfish are not wild animals, so for one to be living in a river would be about the equivalent of a golden retriever living in the woods. Goldfish do not populate rivers, however, they can be commonly found in outdoor ponds.
Goldfish were breed to be pets, they have never lived in the wild. Some people do set them free into rivers and streams, they generally get parisites and fungal infections and do not survive long.
Goldfish cannot live in rivers, they are 100% aquarium fish. They do not have strong enough immune systems to live in the wild and they cannot survive the fall and rise of the temperaure outside year round. Also river water will be to rapid for the fish to swim in.
Yes they do eat pufferfish. But oddly, they are not posioned.
They will all eat one anothers young but adults should get along OK. I do not understand why you would wish to keep wild Rudd in with domesticated Goldfish and Orf though.
yes a axolotl can eat a goldfish
No. They eat goldfish flakes.
There are a great many plants that goldfish will not eat. Goldfish will not eat plants like trees for example.
Guppies don't get large enought to eat goldfish. They will eat anything they can fit in their mouth. The goldfish might eat your guppies though.-Melchisedek
In nature there are many kinds of tiny macropods, microscopic algaes and other things in the water when goldfish breed in spring under normal/wild conditions. These 'baby goldfish foods' can be purchased at most good pet shops
