Freshwater Medications and Protectives
Freshwater aquarium medications and protective agents help manage critical situations and protect fish during stress and recovery: antiparasitics, antibacterials, antifungals, anti-stress adjuvants, and natural solutions (e.g., catappa/tannins).

What you'll find: targeted treatments for external parasites (ich, costia, trichodina), bacterial infections (frayed fins, reddening), fungal infections (white fuzz), and protective adjuvants for mucous membranes/vitamins; natural extracts (catappa/blackwater) for slightly acidic water and calmer fish.
Correct use (general guidelines): when possible, isolate in a hospital tank; remove carbon/resins and turn off UV/ozone during the cycle; respect dosages/times on the label and perform the scheduled water change at the end of the treatment.
Compatibility & warnings: many medications are not shrimp-safe or can damage plants/biological filters. Always check for “shrimp/plant safe” and do not mix similar products. In the presence of shrimp or sensitive species, consider soft remedies (catappa, therapeutic salt/separate baths) or the use of a hospital tank.
Prevention: quarantine new additions, balanced diet, filter maintenance, and stable parameters reduce the risk of recurrence. Integrate water conditioners/bacterial activators when indicated.
Tip: plan the treatment step-by-step (probable diagnosis → hospital tank → protocol → final change). During treatment, increase oxygenation and monitor ammonia/nitrites: biology can slow down.
