Hello fellow aquarists! If you have any questions about raising ornamental fish , you can directly search for fish farming experts and keywords on the entire Internet, so that we can easily raise water and happily raise fish.

Aquarists often ask this question, what issues should I pay attention to when raising Luohan ? I want to raise koi or goldfish, or even high-end goldfish, or ordinary small goldfish. What issues should I pay attention to? Can you explain

in detail?

In fact, I think that fish farming, if we look at it from a broad perspective, it should be self-explanatory.

Although there are definitely individual differences among each type of ornamental fish, the general problem is that there are only a few fish over and over again.

Large water body, good water quality, suitable water temperature and feeding

Large water body breeding means low density.

Of course, depending on the individual differences of different ornamental fish, some ornamental fish may have certain requirements for high water levels. For example, many goldfish species are not suitable for high water levels at all.

However, this also depends on the size, variety and body shape of the individual goldfish, especially the size of the individual, which is different, a small fry of 3 or 5 cm and an adult Thai lion goldfish of 20 cm , can their requirements for high water levels be the same?

If the water level is too high, small fish will struggle to swim or easily lose their drift. If the water level is too low, the big fish will not be able to show its dorsal fin, so how can it swim? Shouldn't there be a height suitable for playfulness?

This all depends on the actual situation. Lanshou without dorsal fin and lion head and gilt with dorsal fin cannot have the same water level requirements.

Good water quality requires not only clear and transparent water, but also a pH suitable for ornamental fish, and each ornamental fish is different.

The remaining water temperature and food requirements are even more different. However, these general necessary conditions must be known before raising fish. Does the

filtering system have different features, suitability, and power?

We say, fish farming, whether there should be a filtration system, whether the filtration system is suitable or the filtration system is powerful are not the same thing.

It is not impossible to raise fish without a filtration system, but it definitely requires personal diligence and low-density and wide water bodies.

For example, when raising goldfish using the ancient method, the wooden sea or tiger head basin in the past had a very large water body, but how many goldfish were kept in it?

But now, we just keep goldfish in the whole small fish tank, and we also think about raising fish without filter, just by cultivating some moss, and it will be done? As long as the density of

is high, it cannot be separated from the filtering system. The low density of can be completely ignored.

Then there is the question of whether the filtering system is appropriate.

generally requires the breeding density of our ornamental fish to be suitable for the original filter system . In this way, it is relatively simple for us to raise ornamental fish, and we do not have to go to great lengths to carry out various modifications.

What is the appropriate breeding density for ornamental fish in a filtration system?

I think that at least under the current circumstances, even if a large number of ornamental fish are fed, the water quality will be stable. Even if the power is out for a day or two, the ornamental fish will not die due to lack of oxygen or the water quality will immediately deteriorate. This is More suitable for the stocking density of the existing filtration system.

Why do some aquarists, as soon as the ornamental fish enter the tank, everything is over, the water quality immediately becomes a pot of slurry, the ornamental fish often suffer from various surface rot diseases, and various problems of water quality collapse arise?

may not necessarily be a water problem. In most cases, the density of fish is too high and is not suitable for the filtering capacity of the fish tank.

So here you go, stop eating, change water, add water purifier, nitrifying bacteria , all of them are ineffective. At this point, you still don’t understand what’s going on?

It’s not that we didn’t choose the right fish, the fish are seriously ill, or there are too many fish, these are the two problems.

Powerful filtration can moderately increase the breeding density, but it also increases the difficulty of breeding.

Many aquarists feel that as long as the filtration system is more powerful, we can leave it alone for a long time and reduce the difficulty of feeding.

That's not necessarily the case, it also depends on how dense it is?

Under the existing conditions, it is not impossible to change the filtering appropriately, or the filtering of the cylinder itself is too weak.

But we must understand that behind the powerful filtering of , it means that there are more filter materials and the water flow must be strong. Some fish cannot adapt to the large water flow.

If the density of ornamental fish is too high, the feces may seriously contaminate the filter material over time, which requires us to do a lot of work. Even if we are not paying attention, the toxins in the water may exceed the standard, and we will not know it because it is very likely It is the dirt and stagnant water areas of the filter material that continue to release toxins.

Therefore, these problems are complementary to each other, and they are both too much and too little.

This does not mean that fish farming must require a filtration system, nor does it necessarily become a necessary condition for raising ornamental fish.

However, if we look at the problem from the other side, a filtration system should still be necessary for most ornamental fish, especially fish in glass aquariums, unless they are small fish with extremely low density.

I am an experienced fish farmer, please stay tuned for more ornamental fish issues, thank you!
