with metronidazole 1, reason: The water quality that parrot fish lives is too poor can bring about the breeding of yuan Sheng insect. Because the protozoon lives in the body of the parrot fish all the time, it only appears when the water quality deteriorates. Parasitized by yuansheng worms, it will lead to the disease of rotten head of parrot fish.
2. Solution: First of all, the parrot fish should be isolated, and the water temperature should be raised by 2 degrees, preferably to 30 degrees. Install the oxygen pump and heating rod, then clean the affected area with hydrogen peroxide, and finally take a medicated bath with metronidazole.
with erythromycin 1. Reason: Parrot fish will be infected by flagellates if they are malnourished for a long time. Flagellates absorb nutrients in the intestine, forming a vicious circle. The increase of flagellate reproduction will weaken the absorption capacity of the intestinal mucosa of parrot fish. Rotten head disease is caused by lack of calcium, phosphorus and vitamin D.
2. Treatment: First of all, it is necessary to isolate and warm up, and then prepare anti-inflammatory and bactericidal drugs, such as hydrogen peroxide, erythromycin ointment, metronidazole powder, etc. Then fish out the parrot fish, dry the water of the fish body, and begin to clean up the festering part of the head. If there is pus in the festering part, be sure to squeeze it clean first. Then clean up the rotten meat and other putrefaction, wash it with hydrogen peroxide after cleaning up, and then fill the rotten hole with metronidazole and seal it with erythromycin, which is conducive to the absorption of drugs. If it is effective, it is better to treat it again every other day, and it can be cured three times in a row.
