and bear paws and fish
Welcome friends back to this little different pet fish column again, I am the fish and bear paw have both.
Recently, more and more ornamental fish infected with external parasites are increasing, after all, autumn is coming, which is understandable.
In the past few days, he has helped several aquarists diagnose the disease of ornamental fish, and found that many aquarists have a serious misunderstanding when treating ornamental fish diseases.
This misunderstanding is that as soon as the ornamental fish is seen rubbing the tank, it is immediately concluded that the ornamental fish are 100% infected with external parasites.
Is this really the case?
For example, this morning, an aquarist's koi had a rubbing tank, and the aquarist came to share a strange thing with The Boy.
He said that his koi had rubbed the tank, but after several days of insecticide, it had no effect at all. Not only that, but the koi seems to be getting worse and worse.
To be honest, A similar situation has been seen five times recently.
After simple communication, the answer slowly became simpler – because their ornamental fish were not actually infected with external parasites.
Since there is no infection, why do ornamental fish rub the tank?
Aquarists are a little more restless, and listen to the hustle and bustle.

Koi in the rubbing tank
In order to distinguish whether it is a parasite-caused rubbing tank, we must first understand what the parasite-induced rubbing tank looks like.
In the aquarium circle, there are three types of parasites: endogenous, exogenous and gill parasites. We are talking about expatials today, that is, bugs that parasitize the surface of ornamental fish, and have nothing to do with bugs in the stomachs and gills of ornamental fish.
If the external mail breeds on the surface of the ornamental fish, the fish will feel itchy, which will cause the phenomenon of the ornamental fish rubbing the tank, which is understandable.
There are two main categories of common expatials: arthropods and protozoa.
For example, the anchor-headed flea, which belongs to arthropods, will cause ornamental fish to rub the tank, but this bug has an advantage, that is, it is easy to identify, most of which is visible to the naked eye. In this case, aquaters will not misjudge.
The real trouble is the protozoa.
Except for small melon worms, most of the native insects are invisible to the naked eye, which is the root cause of misjudgment by aquarists.
For example, wheelworms, ringworms, three-generation worms and ciliates, without a microscope, it is difficult to determine which kind of bug is messing around in your fish tank.
Here, Hezai shares the characteristics of three parasitic infections for easy identification by novices.
If it is really an exogenous infection of fish, most have three characteristics.
First, mucus secretion on the surface of the body increases. This is the immune system of ornamental fish at work, which is a good thing for ornamental fish and a disaster for fish tank water quality.
The second, high-frequency rubbing cylinder. note! I'm talking about high-frequency rubbing cylinders, not occasional cylinders.
Third, if there is bleeding, there should be punctate blood spots, not filamentous ones.
With the above three characteristics, we can basically conclude that your ornamental fish is infected with expatriates.
In addition, there are actually two situations that can also cause ornamental fish to rub the tank, but these two situations are not related to parasites.
Fish farming tips: If it is confirmed that the infection is sent, it is recommended that you use appropriate insecticides to deal with it. Expensive large fish can use an extended version of the large white flakes, and cheap fish can use a combination of copper sulfate and ferrous sulfate. If it is a scaleless fish, it is best to use exogenous fish medicine corresponding to the fish species.
Fish medicine for the squirrel
Let's put the fish aside, and when do we imagine humans itching?
In addition to being bitten by mosquitoes, is it also itchy when infected with some pathogenic bacteria? We usually call this disease dermatitis. (Divided into bacterial dermatitis and fungal dermatitis)
Yes, bacterial infections can also cause itching on the surface of ornamental fish, and ornamental fish can also develop fish diseases similar to dermatitis.
When the body surface of the ornamental fish is infected by bacteria, the diseased fish will also have the phenomenon of rubbing the tank, but the frequency of rubbing the tank is not high, and a large number of red blood will appear on the body surface of the diseased fish.
note! If only red blood appears and there is no rubbing of the tank, in most cases, it is not necessary to treat.
If there is both a rubbing tank and a large amount of red blood, antibiotic treatment, such as furacillin or enrofloxacin, is recommended.
Conclusion: When this happens, remember not to put insecticides, not only is it useless, but it can also kill your fish.
Let's start with a little story!
An aquarist once came to ask him about fish farming, and he said that his goldfish would occasionally rub the tank and ask me what fish medicine was better.
So I asked for a lot of details.
When we have studied the problem, the aquarist began to be silly.
Why Silly Fun?
Because that's not really a cylinder at all.
The real rubbing tank is that the fish body has obvious contact with the glass, and the frequency is very high, at least you can see it three or four times a minute.
And this cute aquarist saw something different.
First of all, its goldfish did make a rubbing action, but the man's body did not really touch the glass.
Secondly, its fish make so-called "rubbing tank movements" infrequently, only occasionally.
Again, its fish are always rubbing in the same place, and it seems that only that place can make it rub very cool.
Attention! If your ornamental fish also appear these characteristics, you must not panic.
Your ornamental fish is neither infected with external mail, nor infected with pathogenic bacteria, in fact, people are playing with water!
The truth is this – some fish tanks have a high wattage of the circulating pump, causing the water to flow faster. At this time, it is easy to form a vortex-like place in a corner of the water body that is invisible to the naked eye. When watching the fish swim to this place, it will feel very cool, so it "turned over", and many friends mistakenly believed that this turning action was a rubbing tank.
Conclusion: Sometimes, when the ornamental fish make the "rubbing tank" action, they are actually not sick, and people are just playing happily.
The words in the heart of the boy: Watching fish rubbing the tank is a very common phenomenon. But cases of dead fish resulting in this common phenomenon are also common. If you want not to face the embarrassment of "good intentions doing bad things", the best way is to judge the fish disease correctly. However, judging fish disease is a very testing skill, there is no more than 20 years of fish farming experience, do not easily say that you will give ornamental fish to see a doctor, otherwise you will definitely be timid.
Knowledge Easter Egg: Everyone knows that British white flakes are too expensive. So is there a more cost-effective expatriate insecticide for ornamental fish? Of course!
