Aquarium Fish Fungicides

Ich Control - Main ingredient is malachite green, which makes it very useful against fungal infections as well as parasites. One drop/gallon for 3 consecutive days.

Established fungal infections in fish are difficult to treat. The key is to get in under control as quickly as possible. Fungi are a group of organisms that feed off organic matter (fish, eggs, food, etc). Very low, or very high temperatures can compound the disease.

The most effective medication is malachite green and formaldehyde. Acriflavine also has benefits - especially on fish eggs.
