for the white frost on the goldfish body? The white frost on the goldfish body may be Saprolegniasis. The main cause of Saprolegniasis is traumatic infection. For example, in fishing or transportation, the fish body is traumatized and the spore bacteria enter, which will cause Saprolegniasis. Saprolegniasis is not obvious in the early stage, in the middle and late stages, the skin on the surface of the fish will appear white floccule, which looks like frosting, and in the later stage, there will be ulceration and other problems. The white frost
on goldfish may also be white spot disease, mainly because the water temperature is too low or the temperature difference is too large. In the early stage of white spot disease, there are only sporadic white spots on the fish body. In the middle stage, the white spots will expand into white patches, and the white spots will be covered with a layer of film.
? 1. If it is Saprolegniasis, if you want to treat it quickly, you need to use malachite green with methyl blue to take a medicated bath for 10-20 minutes every day. After a few days, the hyphae on the body surface of the goldfish will fall off, and the breeder will ensure that the water is clean. The new skin will soon regenerate.
2. If it is white spot disease, the breeder needs to raise the water temperature to 25-28 ℃ first, so that most of the Ichthyophthirius can be killed, and then use the white spot net medicinal bath, which is also 10-20 minutes a day, for a week, the sick fish can be cured.
