Fish kept in aquariums are susceptible to a common fungal infection called saprolegnia, also known as dermatomycosis. It typically manifests when fish are under stress or when the tank’s water quality isn’t optimal. Aquarium owners may find this disease quite concerning because it frequently presents as white, cotton-like growths on the fish’s skin, fins, and gills.
It’s essential to comprehend the signs and causes of saprolegnia in order to stop the infection from spreading throughout your tank. A compromised immune system, fish injuries, and poor water quality can all play a role in the development of this illness. Make sure your fish are healthy and happy by detecting problems early and treating them quickly.
This post will discuss the primary causes of saprolegnia, warning signs to watch out for, and practical treatment options to help you control the illness and maintain the health of your aquarium.

Description of the disease
Saprolegnia, also known as dermatomycosis, is a fungal-based mycotic illness. Freshwater inhabitants are primarily affected by the disease. Phycomycete fungi are the pathology’s causative agent. Fungal spores burst during development and disperse throughout the afflicted fish’s body. It is important to remember that saprolegnia fungi can reproduce sexually, which causes them to grow rapidly.
Kindly take note! Despite coming from fungi, saprolegnia poses no health risks to humans.
Causes of the development of saprolegniosis
Dermatomycosis can develop as a result of a number of things, such as trauma sustained during transit, variations in the salt content of aquarium water, gas regime violations, or fish malnourishment. Saprolegnia frequently develops in conjunction with other illnesses such as branchiomycosis, aeromonosis, pseudomonosis, etc. If the conditions in the aquarium or pond have become favorable for this, the disease affects the body of aquarium fish year-round.
Crucial! The fish won’t contract saprolegnia if you feed them, change the water frequently, and adhere to all maintenance requirements. Even in situations where the aquarium contains pathogens, this is not feasible.
If left untreated, saprolegnia, a common fungal infection in aquarium fish, can have major negative effects on health. This article describes the condition’s visible symptoms, such as white cotton-like growths on the fish, examines its causes, which include stress and low water quality, and offers workable treatment solutions to help your aquatic pets get well.
Characteristic symptoms
A white coating that covers the fins or the entire body of the aquarium fish is the first sign that it has a fungal infection. However, after a few days, a thin layer eventually turns into thick mold. Lesions: blood stains and slightly elevated scales appear where it should have developed. The disease causes the petals to turn pale and start to wither away if it has affected the gills.
The body of the contaminated fish may also exhibit the following symptoms in addition to ulcers and mold marks:
- exhaustion of the body (the fish becomes very thin);
- clouding of the pupil;
- appearance of a film on the eyes;
- decreased activity;
- deterioration of appetite or complete loss of it;
- sticking of the rays of the fins (they gradually delaminate or break).
The diseased fish starts to exhibit severe lethargy. The pet does not have much time left in such a depleted state, so if the proper treatment is not started, it will pass away within a few days.
Treatment of dermatomycosis
The aquarium’s temperature must be raised to the advised 26 °C in order to lessen the fungus’ activity. Regardless of the medication selected, this is how fish therapy for dermatomycosis should get started. Next, drugs that successfully treat the fungal infection are used. Typically, methods like malachite green, copper sulfate, or ordinary salt are employed. Let’s examine each medication in isolation.
Malachite green
A solution containing 1 milliliter of the medication per 100 liters of water must be made. The contaminated fish needs to be submerged in clean water after spending 40–60 minutes in the prepared solution. The process can be repeated if needed, but not before five days have passed.
Copper sulfate
Fish with fungal infections on their bodies respond well to a copper sulfate bath. One milliliter of copper sulfate must be added to ten liters of water in order to prepare the medication. For thirty minutes, submerge the fish in the prepared solution. After seven to ten days, resume the therapy regimen.
Methylene blue
An additional successful treatment for dermatomycosis. 50 milliliters of methylene blue must be added to one liter of clean water in order to make a medicinal bath. The aquarium animal needs to be left in the mixture for a full day. This is sufficient time to eradicate the fungus.
Salt
A quick fix that works wonders for saprolegniosis. The fish must be placed in a 5% table salt solution that you have made. It must be put in an aquarium with fresh water after five minutes. The process can be repeated in a week if needed.
Kindly take note! Manganese solution disinfection is required for all aquarium decorations, plants, and soil where the infected fish resided. To eliminate all spores and dirt, this is required.
Drug therapy
Baths are not the only remedy for saprolegniosis. Pharmacy medications effectively treat this illness. The ones that work the best are listed below.
Medication for fish saprolegniosis (Table).
To avoid making the condition of the infected fish worse, you must read the manufacturer’s instructions before beginning therapy. Adhering to the recommended dosage is crucial, as potent medications may injure an infirm body.
Sustaining a healthy environment for aquarium fish requires effective management of saprolegnia. Faster treatment and better results are possible when symptoms, such as white or gray cotton-like growths on the fish, are identified early.
You can stop this fungal infection from spreading by taking care of the underlying causes, which include damage or low water quality. Important preventive measures include routine water changes, appropriate tank maintenance, and careful observation of fish behavior.
Your fish can recuperate and flourish if saprolegnia is detected, and treatment with antifungal drugs and better tank conditions can help. You can make sure that your aquarium is a safe and healthy place for all of its inhabitants by being watchful and proactive.
