If it is indeed the swim bladder disease:
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!! Check out
