Swim bladder disease

A swim bladder is an organ that goes by the name air bladder or gas bladder. This organ is created during the embryonic stage from the out-pocketing canal. Within the fish air bladder is two different halves. The front half (dorsal) side covered in a thick tissue, which does not allow for much movement or fluctuation. The bladder is tightly linked to the spine, which prevents it from shifting position. The other half (the ventral side) of the swim bladder is located closer to the tail. When there is air in the bladder the ventral side can vary substantially in size depending on how much gas is present. The chamber of the swim bladder is only linked to the dorsal chamber by a tiny duct, and its position can shift according to a variety of factors. ==Causes==

Fancy goldfish are among the fish most commonly affected by this disorder. The disease may be caused by intestinal parasites or by constipation induced by high nitrate levels from over feeding. In these particular cases, the fish can end up with a distended belly, curved back, impaired swimming, or even death leaving them floating on top of the water. Typically a fish owner would be able to identify whether or not their fish is suffering from this disease. A change in swim pattern, and change in physical shape and appearance, are the most common signs that a fish is struggling with this disease. ==Remedies==

A remedy, which can work within hours, perhaps by countering constipation, is to feed green peas to affected fish. Fish surgeons can also adjust the buoyancy of the fish by placing a stone in the swim bladder or performing a partial removal of the bladder. Maintaining these three factors will give the fish the best chance of not catching this disease. The disease is not contagious, and will not be transmitted to other fish within the same tank. It will be best to separate the fish from others so it can better be treated and have its symptoms observed. By giving them their own separate space will also aid in recovery. It is suggested to keep all pebbles, stones, habitat, floras and other fish accessories out of the tank to give the fish the best chance of survival. ==Notes==
