Can I use fish antibiotics for swim bladder or disease prevention?

Thanks for reaching out about your fish. Antibiotics rarely help these conditions if placed in the water, as fish don't absorb antibiotics through the skin, gills or drink it. Systemic antibiotic (injections) could help. A veterinary visit is highly recommended to assess, determine a cause, and plan a diagnostic/treatment protocol. Acetazolamide in the water can occasionally help. Good luck.

If you believe it is swim bladder disease, fast them for 3 days. Resume feeding bits of cooked and shelled green peas until swimming and defecation are normal. The peas can relieve constipation which can cause swim bladder issues. You can also consider a broad spectrum antibiotic and/or a broad spectrum dewormer for the tank to cover infection and parasites. Look in the aquarium section of the local Petco for products. Follow label directions carefully and remove the carbon filter insert during treatment if indicated.

Thanks for reaching out about Tank. A radiograph or blood work could help provide answers. Radiographs could show a fluid/pus filled swim bladder. Injectable antibiotics could assist. There is little that can be done at home. Good luck.

Either may work to treat ulcers which are caused by bacterial infection. Pristine water quality is just as important, if not more so, than medication. Elevated ammonia or nitrite levels can be stressful as well as toxic. A stressed fish is more likely to become ill. Use a home test kit or submit a water sample for testing. Aim for 0 ppm ammonia and nitrites, with nitrates at 20 ppm or less. If your fish are salt tolerant, you can use aquarium salt (NOT table or Epsom salt) in conjunction with an antibiotic. Dissolve 1 teaspoon of salt per gallon of water in a cup or two of tank water and gently pour it in. This will improve gill function, reduce stress, treat minor infection and aid in recovery. Treat for no more than 14 days then perform a partial water change to decrease salinity. Use only conditioned water that is temperature matched to prevent stress or shock.

Thanks for reaching out about Bacon. If a swim bladder infection and over-distention (causing the floating), systemic antibiotics are needed. Melafix will do little to solve this problem as the medication is not absorbed into the body. Systemic antibiotics are recommended, as in injections. A veterinary visit would be necessary for the prescribing. Check and correct water quality, as this is required for health. Good luck.

Metronidazole is used as an antibiotic against anaerobic bacteria in aquaria as well as an antiprotozoal medication. Dosing will depend on the concentration of the product as well as the size of the tank. Follow label directions carefully and remove the carbon filter insert during treatment.

Pimafix is an acceptable "natural" antifungal treatment. Melafix is for bacterial infections. Kanamycin, erythromycin or metronidazole are good broad spectrum antibiotics. Fungus Cure (by API) is an excellent antifungal. You can find these medications in the aquarium section of most pet stores or even online. Follow label directions carefully and remove the carbon filter insert during treatment if indicated. The cornerstone of any treatment is to first maintain pristine water quality and stable chemistry.
