Goldfish Compatibility

 

When keeping different types of goldfish together in an aquarium, there are several things that should be avoided. Goldfish with large size discrepancies should not be mixed together, because the smaller goldfish could have harder time trying to get its fair share of the food. Another thing to avoid is combining slow swimmers with fast swimmers. For example, fast and agile goldfish types such as the comet and common goldfish should not be mixed with slow movers like the ranchus and lionheads.

 

Mixing other species with goldfish

 

Mixing other species of fish, such as tropical fish, with goldfish is also not recommended. Goldfish tend to be hardier than most tropical fish varieties. They usually do not require a heater in the tank and prefer cooler water temperatures than that of tropical fish, which require temperatures consistently in the 70s to remain healthy.

If given enough time, goldfish will grow significantly larger than most tropical fish. They can also become territorial and aggresive towards other fish species.

The only other fish species that can be safely mixed with goldfish are koi, but this is only possible in a very large pond.

In the past i have put a male beta in with my goldfish and i've never had a problem with it. once the gold fish have gotten bigger than the beta i make sure the beta has shelter that the gold fish are to large to get into so the beta can have somewhere to get away if it wants. But most of the time it's out swimming with the gold fish. Important note ... if you do this make sure you introduce the beta and the goldfish to the tank at the same time so that niether one has aggression problems with something new in its home. and of corse never put more than one beta in the same tank

good insight...
my Ryukins are with 9 tiger barbs and two hammerheads... they get along with each other,,, unfortunately, I have to check if those tiny barbs are eating well... Ryukins get the most of the food...
I like their combination... I like their small world...

Koi should not be put in any aquarium. They need 300 gallons of water each.
