It sounds like a swim bladder issue.  My suggestions would be to treat with Pimafix or another antibacterial fish medicine (check your local pet store with a fish department for details) and feed them peas for awhile.  Since this has been going on for a few days, I reccomend that you treat them immediately.

Nossie and Nicole confirm my thoughts about swim bladder desease.
Most times swim bladder desease is caused by  or indicates the presence of another problem.
As Nossie asvised, check your water parameters asap.
Other reasons could be constipation, serious bacterial or parasitic infection, poor diet or rapid fluctuations in temperature.
Two more reasons can be cancer or tuberculosis or a congenitally deformed bladder
We hope those are NOT the case.

Make sure your fish is not constipated, ... so no food for a couple of days. Then peas. As Nossie and Nicole mentioned. Treat with Pimafix and a good salt tonic ( follow the instructions, please )
Also check the temp and keep it stable for your fishy. Some also recommend live food as a change of diet, just ask your pet shop.

Hope this will help too,

Keep fingers crossed that your fishies will recover asap

Swim Bladder desease does not mean that the fish MUST swim upside down only.

The symptoms are difficulty in maintaining equilibrum and abnormal swimming behaviour.

But if you are convinced it is not swim bladder desease ( I still think it is ) you should contact a vet asap.
Also you shoud isolate your fish in a hospital tank with shallow water. It provides relief for the fish. Treat with salt (sea salt from your pet shop !) Very important to follow the instructions. After 2 weeks you can return your fish into deeper water.

You mentioned you cleaned out the tank. Did you use fresh tap water or old tank water? Did you check the water parameters? How are they? How is the temp in your tank?

ya i am not feeding him i feed them peas every day but i need more i thought about the hospital tank but my lid for my 20 gall broke and i have 2 cats and 2 dogs i should just start a zoo. i will try to treat for swimbladder nomally if one of my fish get it it is gomez he eats way to much somtime i have to trap him so the other ecan eat but we will see
hanna where do u live that a vet would help out a gold fish. there is no way that would happen here. now if a had a sick saltwater fish there woulf be 3 places to go but they dont care for fresh water 

thanks for your help i will update u when i can

Hi Jordan,

I hope I could help... where do you live?
Here in Australia we do have vets who work together with  pet shops and goldfish are pets too, also the phone book here is full of vets.
Can you get Pimafix and Melafix? This is a special fish medication on natural basis. You should be able to get it at least over the net, perhaps on e-bay.
But your fish needs help NOW. I am glad to hear you treat for swim bladder.

Yes, please keep us updated, hope your fish will get better soon.

Wouldn't it be bad to clean out the bottom of the tank every day? I don't really know, I just imagine it wouldn't be helping the cycle if that is the problem.

I suggest keep asking different vets/shops. There has to be somewhere out there that will help! Maybe call some universities or colleges, I've heard of specialists helping people out from there.

But to everyone suggesting just to feed them peas, may I ask why? Just wondering why this would help

I really hope your fish gets better soon!

Hi Andrea

Peas and other vegetables provide goldfish with additional nutrients sometime that are lacking in store bought fish food (pellets, flakes, etc.)  The vitamins in these commercially packaged fish food will slowly degrade over time.  Imagine if children and adults are forced to eat only  canned food everyday. They wouldn't look healthy at all.

Peas will also help the fish's digestive system and perhaps even reverse swim bladder related problems.

Hi Andrea, Peas don't ONLY provide additional nutrients, but they also clean out the digestive tract, this is why it is recommended to feed peas at least once a week.... this reminds me I need to buy frozen peas again....
In case of constipation peas help to get back to normal.

Jordan, as Nossie asked, how are your water parameters? Please test for: Ammonia, Nitrite, Nitrate, pH.

If there is an infection present you shoud think about treating with Melafix/Pimafix or in case the infection is more severe you will need to get antibiotics.

hi guy i woke up this mouring and my my fish are doing good thanks to all. i have a bare bottom tank so cleaning there mess up every day takes about 30 seconds. its not that stressfull for them.i have tested the water its is fine i have 2 aqua clear 70 filters on my 55 gallon tank. they keep the water perfect most of the time they swim up to me and nibble at my hands becuase i hand feed them peas. my dad feeds his koi peas out of a spoon the are huge 2 1/2 feet long and over 10 lbs
