When a fish is unable to control its depth, or starts swimming sideways, upside side down, or head or tail down, it may have "swim bladder disease." A fish with swim bladder disease can be a troubling sight to see, but it can be treated.
If your goldfish is swimming sideways or upside-down, it may have swim bladder disorder. Constipation, enlarged organs, or infection can all cause the swim bladder to stop functioning properly. Swim bladder disorder refers to issues affecting the swim bladder, rather than a single disease.
Depending on the cause, swim bladder disorders may be temporary or permanent. If your fish has a permanent swim bladder disorder, they can still live a full and happy life with some lifestyle modifications.
It is likely dying from being put in an unestablished aquarium, you should test the ammonia and nitrite levels in your tank. It's important not to add any more fish to the aquarium until you can confirm that your ammonia and nitrite levels are at zero.
Your Fish Are Stressed!
Fish suffer terribly from stress. Stress damages the fish's autoimmune system, leaving the animal vulnerable to attack by bacterial diseases and parasites. Stress causes your fish to behave in odd ways, one of which could include lying on the bottom of the tank.
Unfortunately, many cases of swim bladder disease do not respond to any type of treatment. If the fish does not recover in a reasonable period of about one or two weeks of treatment, the humane resolution may be euthanasia.
However, the most common causes for this disorder are overfeeding and/or feeding a poor diet lacking in fiber, which sometimes cause gas in the gastrointestinal tract and can lead to severe constipation that would cause the abdomen to swell, preventing the swim bladder from functioning properly (Mayer and Donnelly, ...
Saltwater fish often have swim bladders that are filled with oil. When the bladder gets too large it can extend into the intestines causing an intestinal blockage, which can kill the fish. Freshwater fish are usually subject to this problem when they are kept in an aquarium for too long and too little water is changed.
This can be due to overeating, overconsumption, low water temperatures, bacterial infections, parasites, or other impaired organs affecting the bladder. 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.
Fortunately, many swim bladder issues will fix themselves as the internal infection clears up. Fish may also eventually expel any built up gases, re-inflate their swim bladder, or do whatever else is required for good health. There are a few things you can do as well, which we will explore below!
Swimbladder infections cause your fish to lose control of their buoyancy, resulting in severe stress and death.

Try to scoop the fish into your aquarium net.

What does a swimbladder look like? A swim bladder can best be described as a thin sausage skin inflated with air. It is a very delicate organ which runs centrally through the core of the fish. The length of it depends upon the species of fish.
The swim bladder is located in the body cavity and is derived from an outpocketing of the digestive tube. It contains gas (usually oxygen) and functions as a hydrostatic, or ballast, organ, enabling the fish to maintain its depth without floating upward or sinking.
The dried swim bladder, or maw, can fetch a price of between $20,000 and $80,000 per kilogram on the black market. Demand for maw stems from its use as an opulent business or wedding gift in China, as well as its value as an investment.
Swim bladder deformation, accumulation of clear fluid within the swim bladder, chronic aerocystitis, and bacteria identified as Aeromonas hydrophila/caviae group and Shewanella xiamenensis were the main findings.
Certain species of bacteria such as Pseudomonas, Aeromonas and Vibrio bacteria can infect fish internally causing an array of symptoms. Usually manifesting as lethargy, clamped fins, reddening of the body and fins.
Bacterial infection of the swim bladder causes fish to lose control of their buoyancy which results in severe stress and untimely death.
