Fish Pen & Pen Forte (Penicillin)
Fish Pen and Fish Pen Forte - Penicillin 250 mg and 500 mg
Fish Pen and Fish Pen Forte are manufactured by Thomas Laboratories and are both Pharmaceutical Grade Fish Antibiotics. They come in penicillin 250 mg and penicillin 500 mg. Currently they can be purchased in 30 and 60 count bottles. Thomas Labs used to make 30, 60 and 100 count bottles but the price of penicillin has gone up significantly and now they are made in bottles sizes of only 30 and 60. Each bottle of Fish Pen and Fish Pen Forte has a safety seal and has directions for fish and fish tank use and clearly shows the expiration date of the medicine.
At FishMoxFishFlex we get 1-2 new shipments of medicine in every week to guarantee that we have the latest expiration dates possible on our fish antibiotics, and as always, place your order before 2 and we'll ship it that day.
