Use Thomas Labs' Fish Pen to knock out the organisms that make your fish sick! Using dosed penicillin, Fish Pen Forte combats bacterial infections common in aquarium fish.
Fish Pen is useful in controlling a number of common fish infections, including pop-eyes, infected eyes, fin & tail rot, gill disease, columnaris disease, skin ulcerations and other bacterial infections in ornamental fish.
Directions: Add one tablet (250 mg) into aquarium for each 10 gallons of water to be treated. Repeat in 24 hours. It is suggested that a partial water change be made between treatments. While duration of treatment depends on type and severity of the infection, it is recommended that extended baths in the medication continue for a minimum of 5 days & for not more than 10 days. Discontinue treatment with this medication if no improvement is noted within 5 days.
Keep out of reach of children. Aquarium use only.
If you are allergic to penicillin, do not put your hand in the tank for three days after treatment.
