Why is my betta gulping air after tank cleaning and fin rot recovery?

Bettas will surface to breathe air. This may be normal. Check the water chemistry though. Elevated ammonia levels may drive him to the surface. Check the temperature as well. Warm water does not hold as much oxygen as cooler waters. Bettas do best between 78 F and 80 F.

Begin by submitting a water sample for quality testing. Most pet stores will do this for free or a nominal fee. High ammonia levels, PH imbalances may be responsible for that. Oxygen concentration and quality of the filters should be determined as well. Lack of oxygenation could be the cause of it. If water quality is good and there are no major imbalances, Bubbles should examined to look for any sign of bacterial/fungal infection and eventually water should be treated. Please do not hesitate to contact us again on the forum or by requesting a consultation (where you can post pictures ) if you have any more questions or to discuss it any further.

Recheck water chemistry to confirm 0 ppm ammonia and nitrites with nitrates at 20 ppm or less. A pH of 7 is fine and they can adjust to more acidic water as long as the change is gradual. Temperature should range between 78 F and 80 F. Plain aquarium salt (NOT table salt or epsom salt) can be used as a general tonic to reduce stress, improve gill function, treat minor infection and aid in recovery. Dissolve 1 teaspoon of salt per gallon of water in a cup or two of tank water and gently pour it into the tank. Perform partial water changes every couple of days to maintain water quality. Treat only the volume of water being replaced. Treat with aquarium salt for no more than 14 days then reassess the condition. An antibiotic, such as kanamycin or erythromycin, can be found in the aquarium section of the local Petco if the salt treatment doesn't help. Follow label directions carefully and remove the carbon filter insert during treatment if indicated.

Thanks for reaching out about Kirky and including a photo, although the photo is out of focus. Swimming to the surface and gulping air is typically and indication of gill disease. Gill disease can be caused by poor water quality, bacterial infections, gill parasites, and metabolic disorders. First, check water quality for pH, ammonia, nitrites and nitrates. Correct problems. Make sure to treat tap water for several hours prior to adding to the tank. If water quality is correct, a veterinary visit for assistance in a diagnostic/treatment plan. A gill clip can be examined under the microscope to determine parasitic or other gill disease. Antibiotics added to the water typically cause more problems than benefit, altering biological filtration. Good luck.

Confirm stable water chemistry and water temperature. Bettas will jump out of the tank of stressed or if water quality is poor. They can breathe air for short periods of time as long as they stay moist. He may recover in a bit.

Thanks for reaching out about Goldie and including photos. Betta fish are buccal breathers and will hang at the surface to gulp the oxygen rich water at the surface. If constantly hanging at the surface or when stops swimming bobs to the surface, that is an indication of a possible swim bladder disease. Then a veterinary visit is recommended. Fish usually sleep in the middle of the water column or behind furniture where they feel safe. Always when concerns, check water quality parameters with a test kit. Good luck.

The first thing that needs to be done is a water quality analysis. If you don't have a test kit, most pet stores sell a basic test kit that measures pH, ammonia, nitrite and nitrate. If any of those are amiss, correct that problem. Laying on the bottom of the tank is often a sign of swim bladder disease. This could be an infection, fluid accumulation or a mass pressing on the swim bladder. All of these create a situation where the swim bladder can not contain air, that allows them to control their buoyancy in the water column. The best treatment for this is seek assistance at a veterinary clinic with experience with fish, and have systemic antibiotics prescribed. A radiographs would be helpful in diagnosis. A good fish veterinarian would probably be able to aspirate the swim bladder and collect a sample for diagnosis. The majority of antibiotics available for fish over-the-counter are not good for internal infections and could possibly make things worse. Good luck.
