What is dropsy disease?

Dropsy isn’t a disease; instead, it’s a bacterial infection caused by ‘Aeromonas bacteria’ that enters the scales of the betta fish. It promotes the deterioration of various organs in the betta fish, including the pivotal kidneys and liver. The decline of kidney function prompts abnormal fluid build-up, which affects the quotidian activities of the fish, making it feel uncomfortable. It may show lethargy in active swimming and eating.

What is swim bladder disease (SBD)?

It is a menagerie of diseases affecting the swim bladder of the betta fish. Usually, it is caused by overfeeding of the betta fish or bacteria. Moreover, a sudden change in the fish tank can also lead to a possible swim bladder disease. The common symptoms of swim bladder disease are as follows:

  • Your betta fish has problems swimming in the tank. It has an imbalance in maintaining buoyancy.
  • Unnatural shaking
  • Lethargy in swimming 
  • Loss of appetite

Before treating the fish with Epsom salt it is recommended that the feeding be stopped for 24 hours.

How does Betta fish Epsom salt bath work? 

Betta fish Epsom salt bath or, for that matter, any aquarium salt bath works on the sole principle of dehydration. When the salt is put into the aquarium water, it interacts with the bacteria, parasites, or fungi that have paved the way for the comorbidity in the fish. 

The bacterial/fungal / parasite body is composed of various fluids. Since there is a higher concentration of Epsom salt water outside the fish than within the body of the bacteria, the fluids diffuse out of the body of the bacteria and thereby infuse dehydration, eventually killing the bacteria.

Another major function of Epsom salt is its function as a laxative. It leeches all the waste out of the betta fish and removes all poisonous elements within the fish’s body. Betta fish Epsom salt treatment can also be absorbed in the fish to help reduce bloating or swelling. The reduction of water allows your pet to return to normal size.
