How Can Gas Bubble Illness Be Treated in Freshwater Fish? - Kwik Pets

The disease's moniker is intriguing. The fish are being disturbed by something that resembles gas bubble disease in fish.

Let me now describe what a gas bubble sickness is in actuality. It occurs when the fish's bloodstream fills with gases and is extremely uncomfortable for the fish.

We wondered if fishes also experience digestive or gastrointestinal problems, similar to how people do. Here, the situation is unique. Bubble gas sickness develops when the pond or aquarium fills up with too much gas and becomes supersaturated, or more concentrated than is ordinarily possible.

This is not a rare condition; rather, the majority of fish keepers are likely familiar with it. As the name suggests, you would notice big gas-filled bubbles on the external area of the fish's body when different species are attacked (though especially in squirrel fish and Anthias).

You can see it plainly and instantly recognize it with your unaided eyes. Fortunately, the illness is not communicable. If germs assault it, the situation might worsen and become life-threatening.

Fish Gas Bubble Disease Causes

This can happen when dissolved gases, such as nitrogen and oxygen, become oversaturated in the water where the fish are residing. When this happens, the dissolved gases escape the solution and produce a gas bubble inside the fish.

The following are some typical causes of fish with gas bubble disease:

  • Unexpected Shifts In Water Pressure:
  • The Water Is Too Hot:
  • Low Levels Of Water Oxygen
  • High Nitrogen Levels In Water
  • Gas-Contaminated Water:
  • Blooms Of Algae

Gas Bubble Disease Treatments

Identifying the source of the microbubbles in the pond or aquarium is crucial in the treatment of gas bubble illness. That might not be as simple as you think!

Since there are numerous probable causes, gas bubble disease treatment is essential to preventing the condition from getting worse. Inspect the aeration, water pumps, and water flow back into the aquarium. Also, keep an eye out for little bubbles on your tank's plants, decorations, or walls. It may be possible to identify whether the filter is the root of the gas supersaturation by momentarily turning off the filtration and checking to see if bubbles are formed. To ensure that all creatures in the aquarium or pond are treated adequately for their symptoms, it is also crucial to evaluate all of the species there.

A very tiny needle and syringe will likely be used to aspirate the bubbles out by your veterinarian. Any treatment plan for gas bubble disease usually includes antibiotic medication. Barometric chambers have occasionally been used if your aquatic practitioner has access to them.

The microbubbles will naturally dissipate over time once the cause of the gas supersaturation in the water has been identified and remedied. Degassing the water will be aided by gentle stirring. Cooler water naturally stores more dissolved gas, therefore decreasing the water's temperature a little bit at a time would also be beneficial.

Fish that have trapped gas bubbles in their bodies are comparable to SCUBA divers who experience the bends. The gases will spontaneously spread out of the fish and the bubble will disappear if the water's oversaturation is removed. Before that occurs, though, the condition might be fatal if the bubbles enter the fish's brain, heart, kidneys, or other vital organs. Even if the superstation is fixed, fish who develop bubbles in their fin capillaries may lose fin tissue because of the obstruction of blood flow to the fins.

How To Avoid Gas Bubble Illness

It's critical to assess all probable sources of gas bubble disease and get rid of them from your pond or aquarium to properly prevent it.

  • Verify that every piping and filter component is securely fastened and sealed.
  • Maintain a proper water level and top it off as necessary. Keep track of when you change your water so you can catch leaks early.
  • When adding more water during water changes, make sure to check the temperature first and maintain it at the same level or within a few degrees.
  • Keep an eye out for tiny bubbles like those in champagne in the water. Never let the aquarium glass, aquarium accessories, or the sides of ponds become overly bubbled.

Apart from all these steps, there is verified product help for the gas bubble illness and Aquatics Fish Tank Filters & Media. Which are: 

biOrb Orb ReefOne Service Kit -  The Biorb service kit is the specialized service kit used by the method of water stabilizer and sponge filter to use clean the aquarium. 

Aquavitro seed 350ml - The product have a nitrifying and denitrifying bacteria blend which helps in cleaning the strained water and adapting to the new fresh water in the aquarium. 


When water is introduced to the aquarium, it should be gradually warmed up to avoid the development of gas bubble sickness. Also, avoid immersing the hose when filling a pond. Spray water from above instead to allow all the gases to be released into the air safely


  1. Fish that have gas bubble sickness may recover.

Because trapped bubbles inside the fish may or may not disappear when gas saturation returns to normal, it is necessary to locate and eliminate the source of the excess gases in order to cure GBD. Some vets choose to lance certain bubbles, however, antibiotics are required to prevent infection following this surgery.
