Yes they can but not betta fish.I (I hope this helps to all of you.)
fish do not stay with the eggs
Just about any fresh water fish. If they are smaller than the other fish they will be eaten if they can't hide in rocks or something. I had goldfish and mosquto fish in an outdoor pond and it worked.
No the male will eat them keep them separate them until they can't fit in the mouth of the goldfish.
I think a goldfish is a consumer because if the other fish's are consumers then goldfish are fish they might be consumers.

Get a second goldfish.
Rule of thumb is to not mix tropical fish and goldfish.
Goldfish urine is toxic to other fish, as well as itself.
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.
They can't stay with either one of them the gold fish will be eaten by both of them.
other goldfish and mabey som catfish
