Hello everyone! If you have any ornamental fish feeding problems, you can directly search for fish raising old ways and keywords on the entire network, such as fish raising old ways, water quality white and turbid, fish raising old ways, ornamental fish black spots, rot disease , etc.
Today, a fish friend's butterfly carp was covered with red bloodshots, especially his tail, which was almost completely red. This was the result of a stage of treatment after some anti-inflammatory drugs were applied.
Then, many aquarius friends will definitely ask, and they will definitely encounter it. Why is this happening? What cannot be escaped must be the water quality problem.

The tank is not well-kepted, which leads to the filtration and cannot be treated
The first reason is that tank is not well-kepted or the water is not well-kepted. This is something that many ornamental fish cannot stand, especially the big fins and big tails of butterfly carp, and fins are very soft and very fragile.
Their requirements for the water quality of the fish tank are much stricter than other ornamental fish, so if the water quality is a little disturbing, the first problem must be the butterfly carp.
Because there are other koi in the fish tank, they are nothing, why are they okay? The tail is not long, not big, not soft, it's that simple.
removes algae and changes water in large quantities, and the water quality changes greatly.
If a large amount of algae explodes in the fish tank, the water quality may acidify. Then we remove a lot of algae or change water in large quantities. Other ornamental fish may be fine, but butterfly carp will also not be able to bear it because the fish fins are weak and are most susceptible to irritation, so a large number of red bloodshots will appear.

Actually, like the butterfly carp with particularly flowing fins and large size. Some people will also see the roots of the tail fins in the fish shop. If it is a little red, we can also accept it. is impossible to play the water quality to the extreme. The end of is often rubbed and hurt, because it is the softest place here.
However, something is wrong with a large number of red bloodshots like this. Regardless of whether the water quality tested meets the standards, they just can't stand the water quality, so there will be problems.
Fighting and friction, density issues
Then there is the fight and friction between butterfly carp and koi, and even koi with faster swimming posture and agile body, they will directly bite the big tail of the butterfly carp, which will also happen.
In many cases, it may not be easily discovered by the owner present.
Even if there is no fighting or biting, as long as is dense, there will definitely be friction between each other . Koi is not afraid at all, but butterfly carp still can't do it.

Acidification, aging, not watching the water change
Finally, it is the acidification and aging of water quality, which directly stimulates the body surface of the butterfly carp. Why do some have acne, some have red blood, and some have bifurcations?
These problems will not come up for no reason, there must be a reason.
So, we have always emphasized that you should be careful when raising butterfly carp in . It is not so easy to raise. should be extra cautious in water quality and density, water change and feeding. must be trapped when changing water, and the water quality should not be too new, and the amount of water should not be too large.
This thing is delicate and attractive.

Fishing fish, one that can involve water quality problems may be pH, the other is that the water quality is too new or too old, and then it is that the water is changed significantly, the tank is wiped, and the filter cotton and filter materials are changed, causing the water body to fluctuation. Finally, the water body toxin exceeds the standard. However, there is another invisible reason, which is that the feeding density of is too high.
Especially for ornamental fish that raise koi, butterfly carp, goldfish, etc., solid color and big tail should be more careful.
I am a fish-raising master. Please pay attention to more ornamental fish questions, thank you!
