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.
