Can you keep minnow with goldfish?

It is not recommended to keep minnows with goldfish. Minnows are small, schooling fish that are often used as feeder fish for larger fish. Goldfish, on the other hand, are larger fish that can grow to be quite aggressive. They may see minnows as food and try to eat them. Additionally, minnows are more susceptible to disease than goldfish, and they can introduce diseases into the aquarium that can harm the goldfish.
