Can I keep my Goldfish with other fish?
Keeping at least two goldfish in an aquarium is recommended to provide companionship and promote activity. Goldfish are generally not aggressive so they can be kept with most community fish provided the other fish are larger than the size of the goldfish's mouth.
Goldfish with extended fins should not be kept with fish that tend to nip fins, eg- tiger barbs. The more unusual goldfish varieties such as the celestial should be kept with their variations as they may find locating and competing for food difficult when housed with other types of fish with superior swimming abilities.
Generally, it is best to keep goldfish with tank mates that have similar swimming abilities to ensure all fish can obtain enough food and swimming space.
