Hello fellow aquarists! If you have any questions about raising ornamental fish , you can directly search the entire Internet for fish farming tips and keywords, such as fish farming tips, white and turbid water quality, fish farming tips, ornamental fish black spots, rot diseases, etc.
If you see the foam on the water surface of the fish tank that persists, you should change the water. If you see some feces residue at the bottom of the tank, you should do something drastic. If you see the water in the fish tank turning slightly green, that is a chlorella outbreak. If you look at the side and see some suspended particles, you can't stand it?
We have to have a tolerance for these problems. Only when our tolerance is exceeded, it is better to take action to deal with them.

1. The water quality of the fish tank always goes through a process of rebirth, development, stability, limit, and reversal.
As the saying goes, everything in the world is the same, and the ecological environment in the fish tank is also the same.
So, in the process from the newborn period to the terminal period, do you become impatient and insist on fixing it as soon as you see a small problem with the water quality?
That’s not necessary, especially before the stable period. Especially before a stabilization period. Especially before a stabilization period.
Many novice aquarists seem to be at a higher level than veterans, or have higher requirements, but we must not forget that firstly, we do not have that level and ability, and secondly, we are too impatient.
2. A small problem with the water quality is not a problem, but a high density of fish or disease is a problem.
Many novice aquarists simply deal with the problem by putting the last thing at the expense of others. They raise the fish at too high a density and buy a tank of diseased fish. They never pay attention to it and just stare at the water quality all day long, looking for problems with the filtration system or nitrifying bacteria. Therefore, this kind of approach of putting the best at the expense of the last thing is bound to cause problems.

Now that we understand that the water quality has a new, developing, and stable stage, then, what are we worried about?
For example, the foam on the water surface in the initial stage of opening the tank may be tiny impurities in the filter material. This will get better on its own with the passage of time.
For example, if you look at the water quality of this fish tank from the front, it is very good. But if you look at it from the side, facing the sun, or turning on the light, you will see that it has some suspended particles.
Isn’t that normal?
In any large space, there will be suspended particles facing the sun. The same is true for indoor spaces. Why don't we deal with it?
So there are reasons why I often say that you can add a dark background paper or illuminate the fish tank light sideways.
is for us to stabilize our emotions and just wait quietly. There is no need to worry about these issues. When the time comes, everything will be restored.

3. Initial stage Brown algae , impurities at the bottom of the tank, yellowish and green
Currently, many of my small fish tanks have foam on the water surface. The reason is very simple. The filter cotton needs to be replaced, and the water and fertilizer need to be replaced. However, because the stocking density is low, the ornamental fish are not a big problem, so why should I care about it? So what if it's a little bubbly?
If you don't like the early stage of brown algae, just wipe it off. If it grows again after wiping it off, then continue to wipe it off. If you are too lazy to wipe it off, add scavenger . If you can't add it and you are too lazy to wipe it off, then keep it. The presence of a very small amount of
will not cause any serious harm to ornamental fish, and they will disappear if the water quality improves.
Why is the water color turning green and yellow again? Change the water. Why not do it?
is obviously very dense and has sufficient light, so how can it be neither yellow nor green? You can change the water in moderation, and you won’t be tired if you change it slowly, so why do you have to rush it?
To put it bluntly, these problems are not problems. Either I don’t want to deal with them at all, or I am too anxious.

It has not developed to the point of irreversibility, and the condition and appetite of the ornamental fish are very good. What are we looking for in a hurry?
If you have to achieve the effect of an air fish tank, it is very simple. Just lower the density and ensure that the ornamental fish are disease-free or simply don't feed the fish, and you can achieve it very quickly. All problems above
can be solved quickly. The question is, have you done this only thing?
I am an experienced fish farmer, please stay tuned for more ornamental fish issues, thank you!
