My flower horn was a very big tummy and don't want to eat anything. It seems it is dying, what will I do?

Your fish has dropsy. This disease is an internal bacterial infection. Maracyn two by Mardel will treat it, but it is pretty much always fatal. This disease almost always develops as a result of poor water conditions. Check for ammonia, nitrite, and nitrate, and correct any problems before adding the medication. Adding medication to dirty water is never a good idea.fitness
