Swim Bladder Disease

This mostly affects fish that have a globoid body shape. A loss of buoyancy is one of the
first indications. The fish stays at the bottom of the aquarium, unable to rise, or float at
the surface only. This is due to the fact that the swim bladder is what helps the fish to
remain buoyant. Any damage to this membrane causes this disease. There is considerable
debate about the cause of this disease and the best way to cure it.
