1. Cause of disease: Skin mildew is also called water mildew and white disease, which is one of the common diseases of ornamental fish. Usually, in the process of fishing or transportation, skin injuries are caused carelessly, or parasites are attacked, so that mold spores enter the wound, and then absorb nutrients from the fish body, forming hyphae to grow inside and outside.
2. Main symptoms: The characteristic of dermatomycosis is cotton-like mycelium. When the parrot fish is just sick, because the mold is small, it can not be seen by the naked eye, generally only when the hyphae appear. After that, the mold will cause tissue necrosis, and the number of hyphae will increase, which will affect the appetite and swimming of fish, and eventually lead to their death.
3. Treatment: After the parrot fish is found to be suffering from skin mildew, it needs to be soaked in 3% salt water for 5-10 minutes every day. If you need to use drugs, you can choose potassium permanganate, malachite green, methylene blue and furacilin, etc. The concentration of different drugs must be paid attention to, if the concentration is too high, the damage to the fish will be greater.
4, how to prevent: want to prevent skin mold disease, the first thing to do is to avoid parrot fish injury, and need to change water regularly, keep the water clean, avoid the entry of parasites. In addition, the growth of mildew can be inhibited by raising the water temperature, and ultraviolet lamps can be installed on the top of the water tank to prevent its reproduction through illumination.
White spot disease is one of the common diseases of tropical fish, which can be infected all the year round, and the morbidity and mortality are relatively high. In the early stage of illness, there will be white spots on the fins and skin, and then it will be covered with the whole body, affecting its appetite. After discovering the disease, it is necessary to replace the new water immediately, keep the water temperature, or soak it with mercurochrome solution.
