A veterinarian specializing in aquatics may charge $50 to $100 for an exam. Fees can vary widely depending on geographic location and clinic.
"Bubble" disease, or swim bladder disease, may be caused by poor water quality, constipation or infection (bacterial or parasites).
You may be able to manage it at home. Check water chemistry using a home test kit or by submitting a water sample for testing. The local Petco may do this for free or for a small fee. Aim for an absence (0 ppm) of ammonia and nitrites with nitrates at 20ppm or less. pH should be as close to 7 as possible and water temp can range from 65 F to 72 F. Goldfish are cold water fish. If necessary, perform a partial water change to stabilize chemistry and/or to improve water quality. Use only conditioned water that is temperature matched to prevent stress or shock. Fast your goldfish for 2-3 days. Resume feeding bits of cooked and shelled peas until swimming and defecation are normal. If needed, a broad spectrum antibiotic can be used to treat any infection. Find one in the aquarium section of the local Petco. Follow label directions carefully and remove the carbon filter insert during treatment if indicated.
