"Why do ornamental fish grow algae?" Yesterday I received a question like this. I was a little surprised and asked the other party to take a picture to show me, however, what grows on the ornamental fish is not an algae, but actually a relatively harmful parasite "anchor head loach", which is pronounced the same as "hairy head", a strange parasite. Anchorhead bream generally appears from June to July, which is the most lively period for anchorhead bream. At this time, the anchorhead usually hides in the scales of the fish, does not show a small tail, and can not be seen without careful care. After two or three days, the characteristics of the anchorhead bream will also be revealed. You will see a short "branch" protruding from the gap in the fish scales, and the top is more than a "ya" gesture, swinging in the water. This is the tail of the anchorhead bream. Anchorhead bream burrows into the fish' bodies, sucks up nutrients, exposes its tail, and if left unchecked, anchor-headed bream can make ornamental fish very thin.
The main reason for the emergence of anchorhead loach is because of seasonal reasons, and anchorhead bream activities are more frequent under the condition of high water temperature. And just the high water temperature is not enough, but also need the water quality dirty, long-term do not change the water, impurities and dirty things piled together, it is easy to appear anchorhead loach. Anchorhead loach seems to specialize in fish with scales, it seems to be loach, heterotypic These non-scaled phosphorus-free anchorhead loach are not easy to attach, but it is still possible for heterotypic fish to attach to it. What should you do if your ornamental fish grow anchorheads?
<h1 class="pgc-h-center-line" > the first step, manually cleared. </h1>
If you can observe the shadow of the anchorhead loach at an early stage, it is best to aim at the fish and immediately fish it out to manually remove the anchorhead bream. Adult words are best identified. This piece is recommended to be cleared with tweezers, which is used to clamp the base of the anchorhead bream, and then pulled directly out of the scales to completely tear it off. If the anchorhead loach is broken, it is recommended to pick it out, leaving it prone to wound infection, and the anchorhead loach that loses its tail will die, and it will rot after not completely tearing it off.
Rip off all the anchorheads you can see. After that, the ornamental fish will have a small area of trauma and bleeding, which needs to be detoxified first. There are still many substances that can be used for disinfection, and the common ones are methyl blue, potassium permanganate, and yellow powder. It is recommended to soak it in potassium permanganate solution for five minutes and then fish it back into the original tank, and the effect of potassium permanganate will be strengthened.

In addition to the anchorhead bream that has been parasitic on the ornamental fish, there are some individuals who have not found the host. The anchorhead bream is removed first so that the ornamental fish are not tortured first. Anchorhead loach in the water is treated with drugs and is an insecticidal pesticide. I've heard people use avermectin, which is a very widely used pesticide, and I can often see my next-door neighbor spraying vegetables there, and each spray has a particularly large taste. However, I do not know the dosage of avermectin, and I recommend that you use "dimethods", according to the concentration of 0.2% to 0.5% of the use, not too much. Speaking of pesticides, a large dose can cause fish to die.
Half a month after the next one, make sure that the anchorhead in the water has been completely removed. The whole course of treatment is about 18 days, and the anchorhead will disappear.
The main precautions for the treatment of anchorhead bream is to be sure to grasp the amount of pesticides, I recommend that you use powder to control the concentration better, emulsion is watery. Pesticides are aimed at insects, so the insecticidal effect is excellent. But it is also harmful to fish, and fish that exceed the dose can also die.
Another way is to re-raise the water, and then dispose of the anchorhead loach on the sick fish and put it in a new water source to raise it.
