Natural Non-Antibiotic Fish Treatment & Preventative Care

Fritz Bactershield is a revolutionary, non-antibiotic solution that helps repair and strengthen a fish’s natural slime coat—the first line of defense against bacterial and fungal infections. Using a unique bio-adhesive matrix with natural oils and extracts, it forms a protective shield around your fish to reduce stress, prevent infections, and support recovery from common ailments.

Safe for use in freshwater, saltwater, reef tanks, plants, and invertebrates, Bactershield is ideal for both preventative care after stressful events and mild cases of disease.
