Many disease symptoms will be clearly visible, such as white streaks, lesions, protruding eyes, and other unusual marks or spots on your fish. If you suspect your fish has a disease, it will fall under the categories of fungal, parasitic, or bacterial. One way to diagnose is by matching fish symptoms to the description of a wide range of API fish remedies, which include treatments specific to Ich disease, Betta fish, and various common symptoms (hole-in-the-head, eye cloud, fin & tail rot, etc.)
Add 9 drops per pint (473 ml) or 18 drops per quart (946 ml) of bowl or aquarium water. For larger aquariums, add ½ teaspoonful (2.5 ml) per gallon (3.8 L) of water. Repeat dose daily for up to 7 days, and then make a water change. Treatment may be repeated, if necessary. For tropical fish use only.
API BETTAFIX fish remedy is completely safe with invertebrates such as snails and shrimps, and will not harm the biological filter or aquarium plants.
