About Mardel Maracyn® Two Provides relief from bacterial infections such as fin and tail rot, popeye and dropsy in fresh and saltwater aquariums. Mardel Maracyn® Two powder is a broad-spectrum antibiotic (minocycline) developed for use in aquariums. Due to its unique properties, it is absorbed by the fish through the skin. During the prescribed treatment, the concentration of minocycline in the fish fluids rises to a therapeutic level and is available to fight systemic infections susceptible to its action. It is primarily effective against gram-negative pathogenic organisms. Internal diseases are more difficult to detect than external ones and early detection is almost impossible. Symptoms of clamped fins, general listlessness, not eating or other unusual behavior can be caused by internal infections. All suspected bacterial infections should be treated immediately. Mardel Maracyn® Two is non-toxic to invertebrates.
