Without a well-stocked cache of broad-spectrum antibiotics like Fish Aid Antibiotics, it’s just a matter of time before your beloved pet fish falls victim to bacterial disease and fungal infections, spread readily and rapidly especially in calamitous times when water treatment systems are offline, and hygiene takes a backseat to survival. Penicillin is effective against treating gram-negative and gram-positive bacterial pathogens that your ornamental fish may fall victim to. It’s manufactured using the same quality standards for safety and potency as any antibiotic labeled for human use, as verified by its USP grade seal. A must-have for every aquarium, home, emergency shelter, supply cache, or bug-out bag, it comes in a bottle of 100 tablets of 250 mgs each. You never know where you’ll be when disaster strikes, and at this affordable price - the lowest you’ll find anywhere - it’s painless to stock multiple locations for maximum preparedness. For pet/ornamental fish use only. Not for use in fish raised as a human food source. Not for human consumption.
