Triple on the swim bladder disease. I hope this helps. Good luck and let us know of the outcome.

Way More Than You Ever Wanted To Know
About Swim Bladder Disease

Why does my goldfish tend to float at the surface of the water and have a hard time going to the bottom of the tank?
Because it's got swim bladder disease.
Swim bladder disease is a multifactorial illness which primarily affects ornamental goldfish which have globoid body shapes, like orandas, ryukins, and fantails. It most often presents as a fish which floats at the surface, or a fish which stays on the bottom and doesn't seem to be able to easily rise. A fish which has normal buoyancy but is listing to one side or the other often does not have swim bladder disease, but may have other diseases.
In order to understand swim bladder disease, a cursory discussion of fish anatomy and physiology is necessary. The swim bladder is a small epithelium-lined sac in the anterior abdomen which is responsible for maintaining buoyancy. It has a close association with blood vessels such that gases can diffuse across into and out of the sac according to the needs of the fish. The sac inflates if the fish needs to be more buoyant, and it deflates if the fish needs to be less buoyant. Goldfish and some other fish have a special addition to this system called the pneumocystic duct, which is a connection between the swim bladder and the esophagus, allowing additional adjustment of buoyancy by letting air out through the digestive tract.
People have debated for years over the cause of swim bladder disease. It is pretty well established now that a number of things can cause swim bladder disease. Some of the things which have been suggested are:
1. A virus. The virus attacks the epithelium of the sac and inflammation occurs which makes the epithelium too thick for gases to diffuse across. Thus the fish is stuck at a certain buoyancy because gases have nowhere to go. This may be more of a factor in non-goldfish species.
2. A bacterium. There is little evidence to support this, but it's widely known that bacterial infections can cause the same kind of thickening of the swim bladder epithelium as viruses.
3. Anatomy. Globoid-shaped fish like ornamental goldfish are predisposed to problems with the swim bladder because their guts are all squashed up in their abdomen. This arrangement predisposes to food impactions, which in turn clog up the pneumocystic duct.
4. Diet. Feeding dry foods which tend to take on water like a sponge and expand in the fish predispose to food impactions. See # 2 above.
What can I do to prevent swim bladder disease?
1. As always, the golden rule of fish disease is WATER QUALITY. If swim bladder disease does have an infectious cause, your fish will be better able to resist this infection (and others) if your water quality is good. Regular water changes and water testing are a must.
2. Pre-soak your flake or pelleted food. This will allow expansion to occur prior to the fish eating it, and will lessen the chance of impaction.
3. Even better, switch to a gel-based food or other food source, i.e. frozen or live food. You can E-mail me at
[email protected] for a recipe for gel food.
Let's say I didn't read this in time. What can I do to treat it?
(Note: Some of this stuff is pretty far out, but effective.)
1. Feed your fish a couple of peas. That's right, peas. Just get some frozen peas, thaw them, and feed them to your fish. A professor of fish medicine at N.C. State College of Veterinary Medicine has done this in several cases with very good results. He thinks that the peas somehow encourage destruction of the impaction. No hard scientific data yet, but it's worth a try.
2. Fast your fish for a couple of days. Withhold all food for three or four days, and sometimes this alone will break up the impaction and return things to normal. Most fish can go a week to ten days without food and be just fine.
3. Periodic aspiration of the swim bladder works very well. Basically, you stick a needle in the swim bladder and suck out some of the air. Not something to be entered into lightly, but does work well. This is not a cure, but a successful treatment. The head veterinarian at the Baltimore Aquarium prefers this method.
4. Partial pneumocystectomy. This is another word for surgical removal of part of the swim bladder. I mention this less as a practical option but more just to let people know that there are vets out there doing X-rays, surgery, general anesthesia, even cancer chemotherapy on fish. If you're interested in more information on this procedure, E-mail me and I'll give you more details and a journal citation if you want.
But the best thing to do is to prevent it from happening in the first place.

Swim Bladder- Swim or air bladder problems sometimes occur in freshwater fish. I have personally seen this is fancy goldfish such as Orandas, Ryunkins, and Shubunkins. When the bladder is effected, the fish will experience equilibrium problems. Sometimes, the problem is not the bladder but other problems which directly affect the bladder. Diseased and inflamed internal organs, improper water conditions or nutrition, and wounds received from fighting with another fish can also effect the equilibrium of the fish. Constipation is also known to affect a fish's swimming ability! Symptoms: The fish has problems swimming correctly. They may appear to be standing on their head, or floating to the surface and struggling to go down to the bottom, or possibly even have problems removing themselves from the bottom. At the later stages of the disease, the fish could lose its balance and swim upside down. Treatment: There is no specific treatment for this dilemma;however, you can try isolating the fish to a quarantine tank in which the water is shallow(this provides relief for the fish). Add one teaspoon of salt per gallon of water. Some individuals will feed thawed out frozen peas and this purges the fish's system and has been noted to help many fish. After 1-2 weeks a return to the main tank with deeper water may be tried. The best advice I can give is to maintain proper water conditions, feed your fish a well balanced diet, and possibly try feeding your goldfish sinking foods rather than floating types. They won't inhale so much air this way. The pellets if soaked in water before feeding will expand before the fish eats them and this has helped a lot. Good luck with this!!
