How to Fix Swim Bladder Disease in Goldfish

If your goldfish is swimming sideways or upside-down, it may have swim bladder disorder. Goldfish have a swim bladder that helps them stay afloat. Constipation, enlarged organs, or infection can all cause the swim bladder to stop functioning properly. In many cases swim bladder disorder can be remedied by changing the fish’s diet or cleaning the tank. Fancy goldfish are more commonly affected than other fish.

Raising Outdoor Goldfish

Outdoor goldfish are exactly the same as indoor goldfish, only they grow much bigger. A typical goldfish can grow to 12 inches or more, if its environment is right. The bigger the pond, the bigger the fish and it’s all related to the amount of oxygen the goldfish has available (surface oxygen).

Getting Started

If you want to have some outdoor goldfish to entertain your guest, or simply want a fish to keep your backyard pond occupied with life, then you need to make the pond habitable for them:

If you have a winter freeze in your area, you need to provide a pond that’s at least 4 feet deep. If the outdoor goldfish in your pond get frozen, they’ll die. They will need at least a half foot of unfrozen water to survive the winter, since they just lay on bottom during a freeze up at pretty much hibernate.

Goldfish aren’t hard for a predator, particularly flying predatory birds to spot and swoop down on, since goldfish prefer to stay near the oxygen rich surface of the pond. Depending on the circumstances you may want to attempt to fence the pond in, to keep your fish numbers high. Some Asian outdoor goldfish breeders train dogs to bark at the birds, which can be effective also.

You can either put a pump driven filtration system in, or research way to create a natural filtration system in your pond to keep bacteria levels down and keep the water from clouding up. Don’t think the water will naturally keep itself clean, because the goldfish will reproduce and grow much larger than they would indoors making clouding just as much of a problem.


It’s hard to over-feed outdoor goldfish, since
