"Red nose scissors, excellent group swimming, good water quality nose will be red, can be used as a reflection of water quality indicators of biology, very practical"
When we install the decoration of an aquarium and the water is already raised, then we can safely put the fish down, but someone will definitely ask, what kind of fish should I keep? What fish is good to look at? And how many are appropriate to keep? I think this is a question that many people are thinking about, and today Crazy Jun will answer them for everyone!
First of all, we have to understand the classification of ornamental fish, crazy jun here to introduce two kinds of classification, the first is classified by body type, according to the size of the it can be divided into large fish, medium fish and small fish, common large fish such as elephant fish, dragon fish, cichlid, the volume of these fish is very large.

However, most of the people fed in the grass box are some small and medium-sized fish, the first is due to space limitations, the second is because the small fish are easier to raise and ornamental, and some common small and medium-sized fish such as lamp fish, parrot fish, angelfish.
In addition, there is a more professional classification method, that is, according to the genus to distinguish a variety of fish, the common lamp family (this is a generic name, the lamp family contains the lipid carp family, etc.), medaka and cichlid family, here the crazy Jun recommends that novices can start from the lamp family fish, because the lamp family fish is relatively easy to raise, and the ability to adapt to most of the environment is relatively strong.
In addition, on the number of questions must be noted, it also depends on the size of your tank, in general, a liter of water can raise a centimeter of fish, for example, your tank has 120L, and you raise fish 3 centimeters long, so you can raise 40. After reading these, do you feel that you have increased your knowledge?? It turns out that there is so much learning in fish farming, but crazy jun feels that this kind of benevolence is the wisdom of the benevolent, not necessarily in accordance with the above standards, or according to the specific requirements of their own tank to analyze specifically. Well, after analyzing the above, let's introduce some of the more popular fish species.
The name of this fish is called the colorful immortal, of course, from the name, the immortal must have very high requirements for the growth environment, so although this fish is good-looking, it is very difficult to raise, and novices generally do not recommend raising this fish.
Doesn't the color look bright? Red, green, and blue, the fish's name is very suitable for its characteristics, called neon lights.
The name of this fish is also particularly interesting, called Pauline Lamp, this fish has a particularly interesting place is that it likes to chase food, so special good breeding, it is estimated to be a full-fledged foodie, but the figure is so slim, so that the crazy jun is very envious!
See the triangle on the body, the name of this product is called the triangle lamp, the crazy jun does not understand why, I think it is more suitable to call the triangle black, look at this sharp little eye ~ ~ ~ ~ ~ ~
I will not say the name of this, leave it to all readers to guess what the name is, combine all the features on it, it is its name, and publish the answer in the comments.
And of course there are all kinds of goldfish! But goldfish are very large, so if everyone's tank is relatively small, you should focus on goldfish.
Some people will definitely ask here, what if I want to raise multiple fish in one tank? How I choose, this is a particularly important content! Special special special important! Say it three times! First of all, large fish must not be raised with small fish, which is very understandable, because large fish are easy to cause harm to small fish, and large fish generally eat aquatic grass yo, poor control will eventually affect the ecological balance of the whole tank. Secondly, when choosing fish species, try to choose some fish with a more docile personality, which can be of different species sizes. Finally, when the conditions are suitable, try to raise some working fish, although these fish are not good,but play a very important role in the ecological balance of the whole tank, such as working fish will eat some algae to prevent bursting algae.
Aquarists: After reading this, I could tell that what was in my fish tank was a neon lamp and a Pauline lamp, haha, I always thought it was a breed. It's a long time of knowledge
