Mardel Maracyn Two Bacterial Fish Treatment

Highly effective for common bacterial infections in fish

Mardel Maracyn Two powder is a minocycline-based antibiotic medication which has been shown to be effective against a number of pathogenic bacteria associated with ornamental fish disease. Minocycline is a broad-spectrum antibiotic which is easily absorbed by fish directly through the skin. Maracyn Two is primarily effective against gram-negative pathogenic bacteria which are often associated with internal infections such as dropsy and popeye. Symptoms of clamped fins, swollen eyes or body, labored breathing, patchy coloration, change in swimming behavior or corner-hiding can be signs of possible bacterial infection and may indicate a need for immediate treatment.
