While overfeeding certainly can cause swim bladder disorder (it is not really a disease) and should be avoided, swim bladder disorder has a variety of causes including the shape of your fish and his insides! Goldfish have a very compressed body shape to begin with, and simple constipation or build up of air in their tummies from dried pellets can cause them to have swim bladder disorder. Occasionally it is a symptom of bacterial infection, so that should not be ruled out either.
To treat: Fast the fish for 2-3 days (this sounds mean, but they do well in the wild for sometimes weeks without food), then feed them nothing but the squished insides of green sweet peas. This helps to clean out their system. They will poop green. It is nothing to worry about, and is sortof funny...
This is also a good regimen to do occasionally for a fish that is well, as it prevents the problem in the first place. I do this with my two goldfish once a month, and they have never had SBD once.
A damaged swim bladder.
An upside down goldfish means it has a swim bladder disease. If that disease is detected on your goldfish early, it is treatable with isolation and medicated food. But if the disease is detected too late, the results are irreversible-it is a deadly disease.
Swim bladder disease? http://www.straightdope.com/columns/read/1688/if-a-goldfish-is-swimming-on-its-side-is-this-a-bad-sign
What else would you expect them to swim in? Of course Goldfish swim in water.
No
It probably has swim bladder disease. Swim bladder disease is when your goldfish is constipated, and the food is just building up in its stomach. This also happens when you do not soak their food and there is still air in the food and its puts air in the goldfishes stomach and therefore makes it float. Allow me to warn you this disease could be fatal for your goldfish if not treated. My goldfish had swim bladder disease, and this is what I did to help- 1: I made to sure there was little to no ammonia in the tank 2: I withheld food for 2-3 days. The last thing you want to do is add more air in there and possibly some of the food will digest and your goldfish will be relieved and you may have to do anything else. (Although I wouldn't count on it, this helped my goldfish but didn't stop the SBD. (Swim bladder disease) 3: This could also be caused because of lack of greens, vegi's, and fruit. Your goldfish can't live on a diet of pellets forever. Offer it greens at least 2 a week, or you can get a little clippy thing and you can put some lettuce in there. (My four goldfish chomp down a big piece of lettuce fast, they really love it. But I wouldn't recommend leaving it in there for more than 2 weeks) Also, give them a small slice of an orange. My goldfish love oranges, and I think that the orange really helped my goldfish. Don't leave the orange in for more than four hours because the citrus can bring up the ammonia. 4: Remember: Ryukin's and Pearlscales are prone to this disease because of their round shapes. (They are also prone to dropsy) Almost anyone that works with goldfish will have to work with this disease at least once- so that's ok! Good luck to you and your goldfish!!
