Many novice aquarists want to raise some fish at home, but do not know what fish to raise, do not know where to start, suitable for novice breeding ornamental fish I think should start with cold-water fish, because cold-water fish is cheap, easy to raise, through the cold-water fish first understand some basic knowledge of fish farming, as well as the daily care of fish precautions, and so on the fish has a certain understanding, and can feed the fish, then you can achieve a full pass, handy, raise other fish will be familiar with the road.
So, what are the cold-water ornamental fish suitable for novices? Which of them can be polycultured? What kind of tank culture is suitable for, today I will explain to aquarists.
1. The common cold-water ornamental fish suitable for novices are as follows
(1) Crucian carp
1. Red grass carp, also called golden crucian carp.
It is one of the most primitive ornamental fish, but also the best fish, it is covered with scales, eyes are double eyelids, body color has pure red, red and white flowers, five flowers, etc., is the novice fish entry-level fish, but also the best fish.

2. Cold-water parrot fish
It is a mutation of the red grass carp, and the difference between it and the red grass carp is that there are almost no scales on its body, and the entire eyeball is black, and the color is redder than the red grass carp, and the red grass carp's body is covered with scales, and the eyes are double eyelids.

3. Alloy fish
It has the body of red grass and the tail of a goldfish, and is a species between red grass carp and goldfish.
Alloy fish
Red grass carp, cold-water parrot fish, and alloy fish all belong to crucian carp, which cannot grow too big, and the maximum is 30 cm. They are all very good fish.
(2) Koi
Koi carp belongs to carp, and the difference between it and the previous crucian carp is that the color is bright, the pattern is rich and colorful, there are many varieties, and the ornamental value is high. Common colors are pure red, red and white, Taisho tricolor, Showa tricolor, yellow, black, white, etc.
Koi
Koi fish small fry color is not red, not good-looking, with the passage of time in the growth process, the color gradually becomes gorgeous, so too small koi because the color is not bright, did not achieve the ornamental effect, so will not be on the market, this is the reason why there is no too small koi on the market, the smallest koi is basically more than 15 cm.
Koi
Many koi fish will be eliminated many times during the growth process because of bad patterns, bad body shape, and poor color, so the cost of koi is relatively high, and the price is higher than that of red grass carp, alloy fish, and cold-water parrot fish. Crucian carp does not need to be screened and eliminated in the process of growth, and it can be sold as long as it is raised, so the price is low.
Koi
Due to different genes, koi fish can be divided into scaly fish and soft-scaled fish from the scales, in addition to the color and pattern. Because of the different appearances, colors, and patterns of koi fish, the price difference is very large.
Koi fish can be kept with red grass carp, cold-water parrot fish, alloy fish and gilt goldfish.
(3) Goldfish
Goldfish belong to crucian carp, and the biggest difference between it and red grass carp, alloy fish, cold-water parrot fish and koi fish is that it has a butterfly-shaped tail and a short body.

There are many varieties of goldfish, and the common ones that are easier to raise are the following
1. Gilded goldfish
It is the most primitive species of goldfish, which evolved from red grass.
It has a pointed head, a large belly, and a high back. It can be distinguished into long-tailed gilt and short-tailed gilt according to the length of the tail.
Longtail gilt
Short-tailed Chinkin
From the body type, it is divided into ingots gilt goldfish and ordinary gilt goldfish, the body of ingots gilt looks round from the front, the dorsal arch is high, and the angle between the dorsal arch and the fish head is 90 °, which looks like an ingot, so it is called ingots gilt.
Ingot gilt goldfish
The angle between the dorsal bow and the head of the fish is small, and the body shape of the fish deviates from the round, so the price is relatively cheap.
Common gilt goldfish
Gilt goldfish can be polycultured with red grass carp, cold-water parrot fish, and alloy fish, which is the best goldfish species.
2. Lion's head goldfish
It has a large sarcoma on its head, which is very beautiful and has the style of a king, and the white body and red sarcoma on the head are called Hongyun Dangtou.

Second, the previous introduction of several types of cold-water ornamental fish suitable for novices, so what kind of tank culture are they suitable for?
Goldfish are small in size, suitable for raising in aquariums, clay tanks, and porcelain tanks. Goldfish don't have that strong muscles, so they swim more slowly, and even if there is no lid on the tank, they don't have the strength to jump out of the tank.
Red grass carp, alloy fish, cold-water parrot fish, and koi fish are large in size, and are suitable for raising in large aquariums or courtyards and park pools. New fish into the tank because of the lack of adaptation, easy to jump out of the tank, so you need the lid of the fish tank cover for three or four days, and after the fish adapt to the environment, it will not jump.
Cold-water ornamental fish are generally suitable for the temperature of about 15 °C, higher than 25 °C, if the fish density is large, the density needs to be reduced, and the number of water changes should be increased, otherwise it is easy to die. If the water is deep enough, surface icefish can also be fed.
Goldfish are small in size and swim slowly. Crucian carp and koi carp are large and swim fast.
In terms of adapting to the temperature, the crucian carp, koi fish and goldfish can be polycultured, but because the goldfish are small in size and swim slowly, goldfish and koi, and the polyculture of koi crucian carp will not only affect the ornamental effect, but also the goldfish will be easily aggrieved when feeding, and it is easy to be injured by the koi crucian carp. Therefore, crucian carp and koi fish can be polycultured, and goldfish are best kept separately, but different species of goldfish can be polycultured.
The above kinds of fish are suitable for novices, they are more solid and durable fish, and do not need to be heated, aquarists can choose the right fish according to their own fish tank size and their own preferences. When you have mastered some basic knowledge of ornamental fish conservation and the prevention and treatment of some common diseases, you can keep the fish and not die often, then you can try to raise some tropical fish, small fish and other fish you like.
