Fish Erythro Forte Erythromycin 500mg

500 mg Erythromycin Antibiotic

Fish Erythro Forte Erythromycin is used to treat many different types of fish infections caused by bacteria


Fish Erythro Forte Erythromycin exerts a broad range anti-bacterial action on both gram-positive and some gram-negative bacteria. It is generally more effective in gram-positive infections.
Protect your fish from illness with Fish Erythromycin (Fish Mycin) fish tablets. This broad spectrum antibiotic helps treat and control bacterial diseases including bacterial gill disease, body slime, furunculosis, hemorrhagic septicemia and mouth fungus. Help your finned friend regain his strength or prevent infections from spreading. The tablets are safe for freshwater and saltwater tanks.

Add one tablet (500 mg) into aquarium for each 20 gallons of water. Repeat in 24 hours. It is suggested that a partial water change be made between treatments. While treatment duration depends on the type and severity of infection, it is recommended that extended baths in the medication continue for a minimum of 5 days and for not more than 10 days. Discontinue treatment if no improvement is noted within 5 days.

Fish Erythro Forte Erythromycin 500mg is a Thomas Lab Fish Mycin alterternative.

For aquarium and ornamental fish use only. Not for human consumption.
