Why Do Goldfish Lie on the Bottom of the Tank?
Swim bladder disorder refers to a collection of issues affecting the swim bladder, rather than a single disease. Although commonly seen in goldfish and bettas , it can strike virtually any species of fish. Affected fish will exhibit problems with buoyancy, that is, they'll have difficulty controlling their ability to float or sink. Other physical signs such as a distended belly or curved back may also be present.
Goldfish that sink to the bottom of the tank often suffer from disorders in the swim bladder, where digestive gases are exchanged. Swim bladder malfunctions affect buoyancy. Several factors impact the swim bladder, including infection, tank depth and width or outside environmental influences. If buoyancy issues continue for a period of time, the fish is unable to feed or reach surface water. A distended stomach is the major cause of swim bladder problems.
