Tetracycline for fish is a type of antibiotic that is used to treat bacterial infections not only in fish but also in humans. When used for fish it is usually expected to remedy topical diseases of the skin, such as ulcers or fin rot. Tetracycline is best administered by adding it to the fish's food.

The drug tetracycline is a type of antibiotic. In humans it is prescribed for any number of conditions, including acne, urinary tract infections, as well as other bacterial infections. Typically it is taken orally in pill form.

This type of medication can also be used for treating animals, including fish. Tetracycline for fish can be used for types of bacterial infections that endanger these animals. The typical signs of a bacterial infection in fish include swollen eyes or abdomens, or red streaks or spots on the animal's skin.

Specifically, tetracycline for fish is used to treat external ailments. It is recommended for tail and fin rot, a disease in which the fins of a fish appear to be decaying. It may also be used to treat ulcers on the skin, different types of growths or nodules, and different colored streaks on the skin. It is also used to treat scale protrusion, a disease in which the fish's scales stick out in unusual manner and which is caused by a bacterial infection.


Although tetracycline for fish may remedy the health problems fish are having, it is important to attempt to discover the root cause of the problem. Water quality in the tank as well as the filtration system and any other foreign objects in the tank should be checked. Discovering the cause of these infections can help to prevent the fish from becoming ill again in the future. It may be necessary to treat the water and clean the tank in order to prevent further health problems.

When treating fish for illness, tetracycline for fish can be added directly to the tank, although this is not ideal. It is best when the infected fish actually consume the antibiotic to ensure that the animal gets the full benefits. The antibiotic can be added to the fish's food when it is put into the water. It is recommended that fish should be fed when they are sufficiently hungry to not hesitate in consuming the antibiotic along with their regular food.
