What other fish can you mix with your comet goldfish besides goldfish and koi?

Answer 1

Similar sized goldfish and their variants (golden orfe, etc) should be okay as should other carp species and tench. Just make sure all the fish are getting their share of food and there are no major size differences. Sturgeon are often kept alongside koi at retailers so I would imagine they are fine, too.

Answer 2

Yes, they are both coldwater fish, ad related species. They need a min. of 20 gal. ea. to grow to full size and live a normal life span of upwards of 25 years. If not given enough space, they will die after a year or so. The fancy finned goldfish are mutant and not found in the wild, as a consequence they are less hardy and need warmer temperature waters, so I wouldn't put them with koi.

Answer 3

Any cold water species that will not be small enough for the goldfish to eat. Unfortunately, there aren't a lot of those, so the best thing to mix with goldfish is more goldfish, if you have enough space. There are many different kinds of goldfish you can mix with each other.

Answer 4

Well you can't add tropical fish because they like warm water. You can add it with a Fantail goldfish they are very friendly fish by the way you can't add them with a betta fish (a goldfish) they'll kill it for sure you can mostly put it with other goldfish.

Answer 5

Koi can be kept with Goldfish and other coldwater species in an aquarium. However, Koi get very large and should be kept only in very large aquariums. You should not house Koi with tropicals.

Answer 6

Most any aggressive larger fish will kill it.

Answer 7

Due to the areas that typically house koi, the only predator that would typically eat them would be large birds, or animals

Answer 8

mostly minows
