Fish mycosis-water mold

Signs of infection obvious signs of infection are cottonlike vegetations, usually white, but sometimes gray black to green. The fungus usually starts in the torso, but it may also originate in a damaged area, which can spread and invade the fins, mouth, eyes, and gills.

Affected fish all fish may be harmed.

Infection details fungi are plants that grow on dead organic matter. A typical mycelium, or mycelium, consists of very fine filaments or external hyphae that pierce dead or decaying tissue and absorb nutrients directly through their cell walls. Therefore, although fungal spores appear in water, healthy fish are resistant to infection. The spores are released from the swollen tip of some outer hyphae and swim freely on two flagella until they fall on the right tissue and begin to grow into another fungal mass. Fungi only attack injured fish, or weak fish in some way. If the invasion appears to be spontaneous, it may be the second infection of tissue damaged by other reasons, such as by skin trematodes. In these cases, both the fungus and the primary infection need treatment, and if left untreated, the fungus can die. Damaged or unfertilized eggs are particularly vulnerable to fungi, while healthy eggs laid in the same mass can hatch normally. It is often wise to remove eggs with fungal parasites to protect healthy eggs from containment during their development.

The recommended treatment is in the aquarium, by testing whether the water is in good condition, whether the water is at the right temperature, and whether the water is not too alkaline (the freshwater aquarium is PH7.2), it can prevent possible infection, many treatments are recommended, but there are some serious disadvantages. Salt water bath is a traditional treatment for freshwater fish diseases, but it can cause inappropriate irritation and need to be changed frequently, and it is not particularly effective to use it alone. Methylene blue is effective for mild cases, but the prescribed dosage will color the water and make it difficult to continuously check the development of the disease. Malachite green can be applied to infected areas, and there are several new special treatments that are usually effective against fungi.

In ponds, fungi usually appear in spring, when the fish are at their weakest, or when they become damaged after spawning, before the wet or cold weather begins, feed balanced and nutritious bait to "fatten" the fish (lump porridge is suitable for fattening bait) and ensure that the PH of the water is satisfactory (between PH6.5~PH7.8), which has the potential to reduce fungal infection. Special fungal treatment agents are already available for ponds. However, according to the environmental conditions, it is best to transfer the infected fish to suitable containers that can maintain more stable conditions for treatment. the wide gap between cold and heat will reduce the effectiveness of drug treatment and promote further infection. For example, to take an old-fashioned bath, be sure to carefully transfer the fish to a large container filled with chlorinated or stale water, ideally oxygenated. Undue irritation to fish should be avoided at any cost. When transferring the fish, wipe off the fungal vegetation on the rain body with cotton wool.
