Fungus in fish: types and solutions

Everything you need to know about how to deal with fungus in fish, home remedies to combat it and the symptoms so you know when to sound the alarm.

Fungi are saprophytic organisms belonging to the kingdom Fungi, probably the least known but important microbial decomposers in ecosystems. They occur naturally in naturealthough these fungi increase in size as the amount of decaying organic matter in the environment increases.

They have a fruiting body consisting of hundreds of threads, with the function of reproducing new structures when attacked by an unknown environment, in this case the body of a fish. These threads are called hyphae and once they reach human tissue, they develop very quickly., because in just one or two days you can already see the first symptoms. The worst thing is that the fungal spores continue to multiply in the environment and can affect other fish.

And the order in which the fungus affects the fish is as follows: the fungus begins the process as if it were a seed. This seed burrows into the fish’s body and penetrates its skin through the development of putative roots. When the fungus is at a later stage, it spreads to the outside of the body., but we must not forget that its roots continue to be located throughout the inside of the animal. Thus, if the process is not stopped, the roots penetrate into the tissues of the fish with irreparable damage, even to the point of destruction.

Their food is dead organic matter found in the aquarium, be it the remains of dirt or food, and even those tissues damaged or destroyed by the fish themselves for numerous reasons. And there are various reasons why fungus can settle in the tissues of this pet’s body, but first of all This may be due to poor hygiene conditions, careless handling that can injure the fish, or unsuitable temperatures..

This problem mainly affects those people who have public aquariums, those who do not take care or precautions when handling fish, and those aquariums that have not been quarantined before introducing new fish. Therefore, if you see white threads or spots, it is most likely a symptom of a fungal disease in your fish. Below is everything you need to know about fungi, how to control them, home remedies for them, and symptoms so you know when to worry:

Types of mushrooms

Most fungi attack fish when their body is weakened., for example, in case of damage to the mucous membrane, wounds and other pathologies. And when the hyphae, that is, what makes up the body of the fungi, penetrate the tissues of the fish, they can cause irreparable harm, including complete destruction. There are more than thirty-five species of fungi that infect fish, which cannot be described in detail in their entirety, so we will focus on the most common:

Genera Saprolegnia and Ahliya.

Without a doubt, it is this type of fungus that most often affects fish living in aquariums. Appears as a result of secondary infections or searching for food, as they survive on dead organic matter, such as dead eggs, although they can parasitize and take advantage of weaker fish.

Thanks to the formation of cotton wool layers on the fish’s body, we will be able to determine when they are affected. The problem is that the threads of this type of fungus grow both outward and inward, which causes serious harm to the fish’s body. Treatment should begin at the initial stage.

Ichthyosporidium hoferi

This fungus usually affects fish such as cichlids and carp. This is rare but has devastating consequences as the affected fish release spores through their excrement and thus contaminate the rest of the fish and the entire aquarium. In addition, it affects all the internal organs of diseased fish and causes the formation of black or brown cysts up to 2 mm in size. The worst part is that there is no known cure for this type of fungus.

branchiomycetes

The fungus Branchiomyces sanguinis and the fungus Branchiomyces demigrans are less responsible for attacking the gills of aquarium fish, causing serious damage such as CO2 poisoning. The result is a malfunction of the animal’s vital organs, leading to suffocation on the surface and rapid breathing. The likelihood that fish will survive this type of fungus is low.

Symptoms caused by fungi

Some of the symptoms that we may observe in our pets when affected by fungi are:

The symptoms are very obvious and we must be careful.The symptoms are very obvious and we must be careful.

You can also place the infected fish in a net in a large container and add two tablespoons, that is about 10-15 grams of salt tea, to about two liters of water for 5-10 minutes. This salt bath will have to be done every day until you manage to kill the fungus on the fish and we see that they swim without problems.

Another option is to use green malachite, that is, a green aqueous solution in a ratio of 1/15,000, in which the fish will be immersed for 10 – 30 seconds. If the bath does not work, it is repeated every 2-3 days, not forgetting that the temperature of the bath should be the same as in the aquarium.

Finally, oxygenated water is a good remedy when fish develop strange growths on their fins or scales. A proportion of 175 ml per 10 liters of water will be enough to keep your pet under water for 10–15 minutes.
