API MELAFIX Freshwater Bacterial Infection Remedy (16 oz)
This product targets bacterial infections and repairs damaged fins, ulcers, and open wounds. It uses a natural, botanical tea tree extract to support rapid healing. Best for community tanks and fish showing early fin damage or ulcers. Use with caution in heavily stressed fish or tanks with sensitive inhabitants, as rapid tissue changes can occur.
Who it’s best for
- Aquarists with fin tears or ulcers needing quick recovery.
- Owners seeking a broad, bacterial-focus treatment for freshwater fish.
Important note
Contains tea tree extract. Avoid overuse and follow dosing directions to prevent potential stress to delicate species.
API LIQUID SUPER ICK CURE (4 oz)
Designed to treat ich (white spot disease) and secondary bacterial infections, this remedy rapidly kills the ich parasite, typically within 24 hours after the first dose. It’s best for small to medium tanks showing initial ich symptoms. Better for new or early-stage infections; may be less effective in heavily infested tanks.
Who it’s best for
- Keepers encountering early ich signs in freshwater or mixed tanks.
- Those seeking a fast-acting solution to kelp parasite outbreaks.
Caution
Ich treatment often requires stepwise dosing. Monitor air-driven filtration and water parameters; abrupt changes can affect stressed fish.
API MELAFIX Freshwater Fish Bacterial Infection Remedy (4 oz)
This 4-ounce bottle provides a compact option for treating bacterial infections and aiding recovery of fins and wounds. It uses the same natural tea tree extract as the larger version, making it suitable for smaller tanks or light-bioload setups. It’s an ideal pick for hobbyists who want a ready-to-use daily treatment without committing to larger quantities.
Who it’s best for
- Owners of small tanks or betta setups needing targeted bacterial treatment.
- Users seeking a compact treatment to complement routine tank maintenance.
Limitation
Smaller bottles require more frequent dosing in larger or heavily infected tanks; plan purchases accordingly to avoid gaps in treatment.
API FIN & BODY CURE Freshwater Fish Powder (10-Count Box)
This powder medication treats body slime, eye cloud, fin and tail rot, open red sores, gill disease, and hemorrhagic septicemia. It may cause slight water discoloration, which can be corrected by adding activated charcoal. Best for cases requiring rapid surface application and easy dosing in community tanks with visible external infections.
Who it’s best for
- Aquarists dealing with multiple external symptoms like fin rot and gill issues.
- Keepers who prefer a powder format for precise, quick dosing.
Limitation
Color changes in water can occur; using activated carbon can help restore water clarity after treatment.

Herbtana is an herbal immune-boosting stimulant designed to reduce parasite infections in freshwater or saltwater aquariums. It targets white spot Ich, Costia, Trichodina, Chilodonella, and skin flukes, supporting clearer skin and normal breathing. It works best as part of an overall health strategy, including water quality and proper quarantine practices.
Who it’s best for
- Aquarists seeking immune support and parasite reduction without harsh chemicals.
- Tank owners adding new fish or managing parasite-prone communities.
Limitation
Herbtana is an immune-boosting product and should be used alongside other recommended water treatments when parasites are present.
Buying Guide: Key Considerations For Fish Tank Medicines
What should you consider before selecting a medicine for your aquarium? Here are practical questions and guidelines to help you decide.
- What is the main issue? Bacterial infection, ich, fungal disease, or parasites? Choose a product targeting the specific problem.
- Tank size and bioload. Larger or heavily stocked tanks may require larger bottles or extended dosing schedules.
- Compatibility. Confirm whether the medicine is suitable for freshwater tanks only or supports mixed or saltwater environments.
- Treatment duration. Some products require multi-day dosing or gradual water parameter adjustments.
- Water parameter impact. Be aware of potential water discoloration or filtration effects and plan for carbon or water changes as needed.
- Quarantine practices. Ideally treat in a quarantine tank to minimize stress on existing fish and reduce exposure to the main community tank.
- Live plants and invertebrates. Some medicines can affect plants or shrimp; verify compatibility if you have a diverse ecosystem.
How to compare products
- Identify the target ailment (bacterial, fungal, Ich, parasites).
- Check dosage guidance and bottle size for your tank volume.
- Consider whether you want an herbal option or a chemical-based treatment.
- Plan for follow-up care, such as water parameter stabilization and carbon filtration adjustments after treatment.

- Q: Should I remove carbon during treatment? A: Some products require carbon removal during dosing, while others may be compatible. Follow the product’s instructions.
- Q: Is treatment safe for freshwater and saltwater tanks? A: Check product labeling. Some medicines are formulated for freshwater only; others support both environments.
