neon - 2017-11-21 Commons have great personality! I won a common almost two years ago at my local fair (I wasn't even in the hobby at the time, the fish is what got me into it.) and he is a wonderful companion. It's such a shame such amazing creatures are given out as prizes and usually die due to lack of care. :( He's currently housed in a twenty gallon with a fantail as a companion. (Before I get attacked for housing them together, they were both introduced to each other at a very young age and get along swimmingly. Otherwise they wouldn't be together.)

Anonymous - 2015-08-29 if you have a light over the tank sunlight is not needed. the more sunlight the more algae. male goldfish are more round than females

Clarice Brough - 2015-08-06 I'm guessing your tank is not yet cycled, and that ammonia is the problem. Read about cycling the aquarium and see if you might think this could be why you are loosing your fish.
Michelle - 2010-05-08 My daughter just won 5 common goldfish at a local carnival. Are they okay overnight (fish stores are closed), what size tank should we get, and are they okay until morning without a tank? The only options we have are a 1 gallon betta kit and a 10 gallon aquarium (we don't have the water or conditioner for the 10 gallon)?

Anonymous - 2014-06-03 Ok, first of all you need more than a ten gallon tank. Number two, look on this website if you need help. It works wonders for me. thegoldfishtank.com
Jessie - 2014-12-23 10 gallon tank will never work for 5 goldfish. 1 Goldfish should at least have 3 gallon (if its a baby) they grow very big and when they are not a baby anymore, they will need at least 10 gallons. I know it kind of sounds crazy but it's just like a person living in a house. For 5 goldfish there should be at least 30 gallon. Goldfish needs lots of space and water. They eat and poop and the poop is going to poison the water then the goldfish is going to pass away really fast. You will always need to put water conditioner in if you are using tap water to make the water safe for the fishes.
Jessie - 2014-12-22 Hi. I got a goldfish today and put him in the tank. He has been staying at the bottom where the rocks are. I tapped the tank to make sure that he was still alive and he moved but hes just staying at the bottom corner. Is there something wrong with him?

Clarice Brough - 2014-12-24 Doesn't sound happy. It could be that he is acclimating and will be fine after a few hours, but if it goes on longer it could be either the tank setup or the water conditions. Check your water parameters. If you're using tap water, you need to add a water conditioner that removes chlorine. If you tank has had fish for awhile, then check the ammonia level. Plants or other hiding places help and make sure no other fish is bothering him.
ron ash - 2014-11-27 I have a 7yr old gold fish in a 10 gal tank. He is about 8 inches, no other fish, keep tank clean, feed him large flake goldfish food. For the last ten days he has not be eating and is stuck on the bottom of the tank. I think this is a bladder problem and I have cleaned his tank and gave him peas but he does not eat. What more can I do?

Clarice Brough - 2014-12-02 It's the eating habits of a goldfish that are the most common cause of swim bladder disease. Poor water quality can contribute, but the most common causes are such things as constipation from excess food, swallowing air, and feeding foods that ferment in the gut. Also, if food is withheld for too long, they loose gas in the gut so are unable to rise.
So feed less... but more often, feed a variety, and feed consistently. Try offering sinking pellets instead of flakes and soak the food for a few moments before feeding, and the peas should also help.
Chloe - 2014-08-31 I have two fresh water fish living in a 96 litre tank with a Tetratec IN 800 filtration system, I preform 10-15% water changes every week and have just recently been bought two more fish, will the size of my tank be enough? The breed of fish are; Common goldfish, two Comet goldfish and a Shubunkin, I'll also be buying a gravel cleaner and an algae scraper very soon, the tank has just been set up and the two new fish are in the quarantine tank for a week or two, any help would be greatly appreciated, also, would a couple small snails be okay in the tank? I'm not buying them till I'm sure everything will be okay, thank you.

Clarice Brough - 2014-09-01 No, unfortunately a 96 ltr tank is only 25 gallons, and will not be near enough water as these fish get older. When small it may work for awhile, but you will soon have to upgrade. As you can see in the aquarium setup info above, goldfish require a minimum of 10 gallons per fish. That is 50 gallons (190 ltr) just for the 5 goldfish.
Jimmy Thai - 2010-07-29 Hi I have 8 hardy common goldfish, and they are juvenile fish. Can I keep them in a 10 gallon tank? Since they are still small. I know that they poop a lot and yeah I have to replace the cartridge every two weeks. Me and my dad are caring for the tank, later on we will buy a 60 gallon aquarium at the pet shop. How many gallons does one goldfish need? How big do these kind of goldfish grow? Do I have to build a pond? My tank has a hanging power filter. I wonder if needed an under gravel filter. I have colorful rocks and a bamboo, I know 8 goldfish need a lot of space so I don’t want them to live with lots of decorations. I’m the one who always cleans the filter. My dad always does the water change. Oh yeah, and I need to know how to clean out the fish tank, because my dad usually takes out all the water with a siphon, so I did some research and it said to siphon out 32 cups of water or 20% but I don’t know. So please tell me some steps. I feed my goldfish “Goldfish Flakes” , and that’s all. I tried feeding them “Goldfish Quick Grow Pellets” but when I threw some in, they ate it but then they spitted them out. I don’t know if they are the right age to eat them yet. What else can small goldfish eat? I don’t know if they can eat live food like water fleas or bloodworms. Please give me a good reply thanks!

Goldfish are fun to watch! Just look at all the different colors of these beautiful fish!
When was this encyclopedia piece published? I would like to reference it for a research proposal.
The article was published on January 8, 2009
