What to do when you find your goldfish swimming upside down
When I saw this upside down goldfish, (yes, we had a goldfish floating upside down) I thought it would be floating lifeless by the next morning. But it wasn't. Although it did not seem too uncomfortable, I assume that it must have been rather disorientating for the poor thing and me being me headed off to the PC to "Google" the phrase "upside down goldfish".
This lens discusses what I learned about swimbladder problems and upside down goldfish and how I cured my poor sick goldfish.

Swimbladder problems
Why do goldfish swim upside down?

The swimbladder is an air-filled sack that is located just under the fish's vertebrae, just at the top of the abdominal cavity. The fish maintains its buoyancy and adjusts its position in the water by inflating and deflating the swimbladder.
The swim-bladder can be affected by various diseases or it may just play up, causing problems with over or under inflation. Anything that affects the normal functioning of the swimbladder is going to cause huge problems for the fish.
However, it's not just swimbladder disease or problems that can cause difficulties with the fish' equilibrium as there are diseases of the other organs that can also affect the fish, such as in the kidneys or the intestines. If the affected organs are swollen then they can cause pressure on the swim-bladder. This is often a problem with fancy goldfish, where the body cavity is abnormally short compared to the size of the fish.

Possible treatments for Swimbladder
Why do goldfish swim upside down?
Treating a sick goldfish is extremely difficult and they often die before you have had time to diagnose the problem. The fish may be constipated and as it can hardly tell you the last time it "went", you are going to have quite a task trying to establish if it is "going" regularly. The only way you can tell if a fish may be constipated is if you see long strands of poo hanging from it.I saw one website that suggested a series of anti-biotic injections may help if it is a swimbladder disease or infection - whaaat? Can you imagine it? Working out what to put it in so you can drive it to the vet and praying that you don't have to do an emergency stop on the way!
This same website said a report suggested "wedging" the fish upright between two objects and that this report was helpful. Whaaat? (Again!)
What two objects do you wedge it with? Hang on, I'll just go and get hubby's vice out of the shed!
One of the more sensible suggestions I saw, was that if you think your goldfish is constipated then put it in a bath of Epsom salts - 70g per litre for 5 minutes, which will act as a laxative. But please remember to use water from the fish tank not the tap, or you may cure the constipation but you will kill it with the chemicals in the tap water!
The problem with that suggested treatment was we did not have any Epsom Salts in the house. Why is it whenever you need a remedy, it is midnight and all the shops are closed?

The treatment I used to help our upside down goldfish
Frozen peas
The first time I "treated" our sick goldfish, it could not get to the peas as they sank to the bottom of the tank. So I got out the smaller goldfish bowl that I use to put the fish in when I am doing a major clean of their tank. As there was less water in the bowl, the fish had less buoyancy, so he was able to feed off the bottom. Once it had eaten the peas, he was fine within a couple of hours. The recovery was extremely rapid.

The goldfish is not sick anymore!

Why did the peas work?
The peas help because it is believed that they clear out the fish's digestive tract by removing food blockages and trapped air. The standard flaked food we give our fish has a lot of protein which can lead to goldfish constipation.

Preventing swimbladder problems from recurring
A varied diet is the answer
Just recently, the fish started swimming upside down again. So I went back onto the net and did some more research.
I discovered that being omnivores goldfish have evolved to eat a wide variety of foods, both animal and vegetable and to thrive they need a range of foods. Fish flakes do not provide all the variety your fish needs.
Goldfish benefit from occasionally having live food such as brine shrimp or daphnia. Brine shrimps are a great source of protein; daphnia are ideal for helping goldfish avoid constipation.
To improve your fish's digestion replace a couple of meals a week with live food but switch off the tank filter before adding it, or it could be filtered before the fish can get to it. Remember to switch it back on again!

Goldfish also enjoy lettuce leaves and fresh spinach. Rinse in clean water, then cut into small pieces and drop them in the tank.
These leaves are a good source of the vitamins and minerals your fish need. They also contain carotenoids. These red and yellow plant pigments may also improve the colouring of your goldfish!

- Wow - imagine all the goldfishies you have saved with this lens! I've never heard of a cure for upside-down fish either...excellent information you've put into this topic and it's incredible how many fish you've managed to turn right side up. I think I would probably just flip the tank over if I didn't land on your lens first. :-)
