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.
Rudd, Orfe, some species of Catfish will all be OK in cold water with Goldfish.
Rudd, Golden Orfe, Blue Dace, some species of Catfish. Check with your local pet shop what coldwater species they can get.
ORFE
Carp, Pike, Trout, Bream, Rudd, Orr, Tench, Barbel, Chub, Dace, Orfe, Catfish, Loaches, Gudgeon, Stickleback, Perch and Eel to name a few.
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
Goldfish do eat water lettuce as part of their diet.

Goldfish are omnivores and may eat smaller goldfish if they are hungry or if there is limited food available. It is not their natural behavior, but it can happen in certain circumstances.
