SWIM BLADDER DISEASE
Symptom:
1.Difficulty in swimming.
2.Always float near the top of the tank.
Usually it will work if you go to the fish shop and just buy a antibiotic or medicine for your poor fish as sometime may be "bacterial infections" as I try it before using a medicine to cure most of my fishes with this problem and it work well and in 3-5 days the fish will recovered.
Here are the step:
Firstly, go to your fish retailer shop ask for swimming bladder medicine .The medicine may come in tablet or solution.
Later just add the medicine in your fish tank according to the amount or dossage required and don't,t take other fish in the tank out as they might have the disease as well.
Lastly ,change the water after 2-3 day and repeat the procedure above until the fish 100% recovered.
Or
you can just removed your fish from nitrate-rich water to reversed flipover problem.
Hope my answer has help you and your poor Goldfish.
Good luck :)
