So, yes goldfish can live in what is considered a nano tank and goldfish tank size isn’t as important as you probably think But why can goldfish live in small aquariums? They get massive AND are dirty. It’s A Fish Thing has many articles that say that you CAN put them in a 20 gallon, or even a smaller tank than that!


Most will say that you need to keep common goldfish in a 75-100 gallon, Ranchu goldfish and other fancy goldfish in a 30 gallon tank. Some say that even 20 gallons for a fantail goldfish is too small. It’s not rare for someone online or even at a petstore to speak strongly against keeping goldfish in small aquariums or bowls and instead recommend fairly large goldfish tank sizes. Some may say you can keep a fantail in a 20 gallon, but it’s still very rare.įor most beginners, even a 20 gallon isn’t in their budget, perhaps they have enough for a 5 or 10 gallon, but that’s about as big as they can afford. For example, a 75 gallon is 4 feet long! For fancy goldfish, the tank size is a bit less strict, but even there they still recommend usually at least a 30 gallon aquarium. A lot of beginners find these tank sizes quite large, for good reason. THANK YOU.Īlmost everyone who has been in the fish hobby for more than 6 months most likely knows that everyone says that that the goldfish tank size would be 30 gallons or more for fancy goldfish and 55-75 gallons or more for common and comets. I FOUND CONVINCING EVIDENCE AND IF YOU WANT TO READ MORE ABOUT THIS TOPIC, PLEASE SCROLL TO THE END OF THIS ARTICLE. HOWEVER, I CAME TO MY OWN CONCLUSION ABOUT GOLDFISH AND BOWLS. WE UNDERSTAND AND APPRECIATE EVERYONE’S OPINIONS. Your own pond. A period of cold temperatures followed by spring-like conditions can really help things along.DISCLAIMER: WE UNDERSTAND THAT THIS IS EXTREMELY CONTROVERSIAL. But because of how large the babies get, it’s really best accomplished in a pond. If you’re talking about trying to breed them at home, that can be done indoors. When some goldfish owners couldn’t (or didn’t want to) care for their big Comets anymore, they did something really bad… They released their fish into a lake in Boulder, Colorado. BIG MISTAKE! Because goldfish proliferate like crazy. We’re talking up to 1,000 eggs at a time in just one spawn! They ended up taking over everything and beating out the native species. But if the pond is stocked full, you will probably need to add in other foods to avoid malnutrition.įor further information on feeding, check out this post. If you keep your fish in a pond, chances are they have access to most of the food they need already. Having a good, nutritious diet is important to their growth and coloration.

These are actually a hybrid cross between a koi and a Comet, not a true goldfish. And get this: They can’t reproduce!Īnd if you look closely… they have tiny “barbels” or whiskers like a koi. This is interesting: If a Comet has nacreous color, it isn’t a Comet anymore – it’s a Shubunkin goldfish. You may have heard about the newer Black Comets on the market. “Sarasa”) are the most commonly found. But they can also be chocolate, yellow or white! The brown ones typically change color with age. They look a lot like the Common goldfish, but they have a longer tail with pointed tips (this is called a “ribbon tail”). This means they have only a tail fin and one anal fin.

Fun fact-the Comet is patriotic! They’re the only goldfish breed the United States has contributed. How did we get the Comet? The first Comet was actually first made by crossing a Veiltail with a Common goldfish! This gave them their longer tail but slim body. The Little-Known Background of the Comet Goldfish
