Medications
Fish medication is available to treat a wide range of external and internal maladies. These medications come in the form of liquid or powder usually and can be used to treat bacterial infections, fungal growth, and parasites both external and internal. Often when a fish has one problem it will develop a second problem, which will compound the medication process. For example when a fungus shows up, it is usually there because it is attacking a wound that may have already been infected with a bacterial infection on the fish and it was an easy target.
