Yes they can but not betta fish.I (I hope this helps to all of you.)
No the male will eat them keep them separate them until they can't fit in the mouth of the goldfish.
No, goldfish do not stay with their eggs. After spawning, goldfish typically scatter their eggs in the water, and they do not provide any care or protection for the eggs or the resulting fry.
Goldfish are best kept with other goldfish or similar coldwater species that can tolerate cooler temperatures and shared tank requirements. Good tankmates for goldfish include white cloud mountain minnows, dojo loaches, weather loaches, and rosy barbs. Avoid fish that may outcompete goldfish for food or nip at their fins, such as tropical fish like angelfish or neon tetras.
I think a goldfish is a consumer because if the other fish's are consumers then goldfish are fish they might be consumers.

Goldfish are omnivores and may eat smaller fish, especially if they are hungry or if the other fish are small enough to fit in their mouths. It is important to provide goldfish with a balanced diet to prevent them from preying on other fish in the tank.
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.
Goldfish differ from other types of fish in their growth rate. Goldfish have the ability to grow continuously throughout their lives, while other types of fish have a set size that they reach and do not continue to grow. This means that goldfish can potentially grow much larger than other fish species.
