Erythromycin for Aquarium Fish

 

Updated 1-16-19

API Aquarium, Pond, fish Erythromycin, for sale Erythromycin is a primarily gram positive antibiotic with a slightly "wider" antimicrobial spectrum to otherwise similar to penicillin.

A popular albeit often incorrectly and over recommended for fish infections. In humans Erythromycin is often used respiratory tract infections, which of coarse does not exist in fish (gills versus lungs).

During treatment Erythromycin is rapidly absorbed in a microbiologically active form into most tissues and phagocytes found in vertebrates (such as fish). Due to the often resulting high concentration of Erythromycin in phagocytes (white blood cells), Erythromycin is actively transported to the area of infection.
Over use of Erythromycin may result in muscle (including heart) and kidney damage, providing electrolytes, in particular calcium while treating with Erythromycin can aid in prevention or reversal of this damage

USE:

The primary disease pathogens for use of Erythromycin are Staphylococcus and Streptococcus (which often includes many eye and mouth infections of fish).
Occasionally these bacterial pathogens can result in fin and tail rot as well.

Erythromycin can generally be combined safely with Triple Sulfa for a more wider spectrum treatment (especially for use against Staphylococcus infections).

Another use for Erythromycin is for cloudy aquariums and cyanobacteria blooms, however Erythromycin Sulfate is much more effective for these applications (as well better for fish pathogens) and most Erythromycin (such as API) is not of this form of Erythromycin.
Sometime in 2019, "AAP Professional Aquarium Treatments" will have this preferred form of Erythromycin available for aquarium/pond use again.

Although often recommended for Columnaris and Fish Fungus, these are simply INCORRECT uses for Erythromycin.

As with ANY treatment regimen, it is extremely important to follow correct procedures that includes addressing ALL water parameters and stressors (including oxidative stress.
Please read this easy to read article and follow ALL advice given as to proper treatment regimens:

Please realize diagnostic charts are generalizations with many inaccuracies such as use for "true" mouth fungus.

FINALLY: While I strongly recommend the use of a UV Sterilizer both before and after treatment (24/7), use of this device should be discontinued during treatment with Erythromycin.
