What is Saprolegnia?
Saprolegnia (SAP) is not an aquatic fungus, it is a Protist that is often mistaken for a fungus. It is commonly found in aquariums, particularly where there is an abundance of decaying organic matter. This can be confused with Columnaris.
Saprolegnia is spread by spores through the air and causes fungal infections in injured or sick fish or amphibians, and often attacks eggs, killing them before they can hatch.
- This fungus spreads and eventually kills the animal.
- Damaged skin or fins.
- Bacteria infections which leads to further skin and fin damage.
- Malachite green.
- Methylene Blue.
- Potassium Permanganate is an effective treatment at the early stages of infection.
- Tincture of Metaphen (tincture of nitromersol)
- Remove fish from aquarium and directly apply drops of 3% Hydrogen peroxide or spray with Terbinafine Hydrochloride (Lamisil AT foot spray) (see image) to the area of the wound for 30 seconds. Repeat daily.
- Some species of this fungus are tolerant to brackish water so salt may not be an effective treatment in advanced cases.
