Want to raise fish and do not want to use the heating rod, you can choose these fish (including some tropical fish) before this we first have to know that the fish are divided into cold water fish and tropical fish, cold water fish as the name suggests is also able to survive in low temperatures, most of which are domestic native fish, they can withstand very low temperatures, both north and south can be raised. Tropical fish are fish living in the tropics, they will survive well in the environment of 20 to 30 degrees, but some of them tropical fish, can withstand lower temperatures, in the case of heating in the northern winter, without heating rods can also be raised indoors.

I believe that many friends have such regrets, I want to try to raise fish, but I am afraid of trouble, especially in winter, I need to insert heating rods, and I feel that I am afraid of electricity and any safety hazards. If there is a fish that you like in winter, you can raise it without heating, how good it would be. So today we will take stock of which ornamental fish can be raised without heating rods to see if there are any fish you like.
<h1 class = "pgc-h-arrow-right" > before this we first need to know that fish are divided into cold-water fish and tropical fish, cold-water fish as the name suggests is also able to survive in low temperatures, most of which are domestic native fish, they can withstand very low temperatures, regardless of the north and south can be raised. Tropical fish are fish living in the tropics, they will survive well in the environment of 20 to 30 degrees, but some of them tropical fish, can withstand lower temperatures, in the case of heating in the northern winter, without heating rods can also be raised indoors. </h1>
First, let's take a look at the cold-water fish
1— Goldfish, grass goldfish
The ornamental fish we see most often in aquarium markets is probably the fish that many people first recognize. They evolved from crucian carp, so they are similar to crucian carp in terms of water temperature tolerance. It can withstand the water temperature of 0 ° ~ 39 °, of course, it can not live in the extreme temperature for a long time. This temperature range is believed to be adaptable to almost all regions.

Tropical fish are fish living in the tropics, they will survive well in the environment of 20 to 30 degrees, but some of them tropical fish, can withstand lower temperatures, in the case of heating in the northern winter, without heating rods can also be raised indoors.
2—Koi
It is also an ornamental fish species cultivated by carp through continuous selection, hybridization, etc. Koi is also a kind of ornamental fish that often appears in outdoor fish ponds and ponds, and many parks and botanical gardens like to raise koi. It can survive in the water at 0° in winter.

3—Look at the medaka
The body length of the guanbei medaka is about 3 to 4 cm, originated in Japan, the color is bright and changeable, it is very ornamental, and the variety is diverse. Compared with the goldfish and koi above, they can be raised with only a small tabletop tank, and they can live well without filtering the oxygen heating equipment. It can live in a water temperature environment of 0 ~ 40 ° C, and the suitable growth temperature is 15 ~ 30 ° C. At present, due to the increasing number of players raising native fish, the back-watching medaka has also received more and more attention.

4—White cloud gold wire
Also known as Tang fish, it is a unique fish species in China, and it is also a national second-level key protected wild animal, which is a national protected animal that can be legally raised. Circulating in the market are artificially bred individuals, the white cloud gold filament body color is bright and colorful, the base of the dorsal fin is red, the other fins are yellow and green, and the edges are transparent. It is a cold-water ornamental fish that is very close to tropical fish. It can survive in a 5° environment, and if your aquatic weed tank is not heated, this fish is definitely the first choice for matching. May my big tang fish go to the world.

5— Chinese fighting fish
Players often refer to it as "Guodou", which lives in the area south of the Yangtze River in China and can be found in small still water bodies such as ditches, ponds and rice paddies. The physique is very strong, like the Thai fighting fish, the fight is very fierce, so it is recommended to raise it alone, if you want to raise more than one, it is recommended that 7, 8 or even more, if you only raise three or four, then the fierce may only live one in the end. It is not harsh on water quality, has pleats, can survive in a low-oxygen environment, and is resistant to low temperatures of 3 °.

6—Sucking loach
A benthic native fish, known as the domestic "scavenger". It lives in streams and needs to be raised in a high-oxygen environment. Breeding has a certain degree of difficulty, generally more professional native tank players like to breed. It can survive at a temperature of about 10 °.

7—Sturgeon
A very common native fish, adult males have a beautiful color during the breeding season, and there are currently some aquarium players who like fish very much, and there are already professionals who do strain purification. Species include high-body sturgeon, volcanic sturgeon and so on. The reproductive ability is not strong, and it is necessary to use river mussels to reproduce, and the females will lay their eggs in the river mussels. The temperature requirements of the salmon are not high, and many players can successfully survive the winter under the water temperature of 1 to 2 °.

8— Broadfin carp, albacore
Commonly known as peach blossom fish, the scientific names are flat-jawed carp, longfin horse-mouthed carp. It is found in streams in China, Korea, and Japan, especially in mountain streams. For this reason, this fish does not like high temperatures and can still swim actively at 5° water temperature. Once the main economic fish species in the mountains, the marriage color is very beautiful during the breeding period, and it is gradually accepted and raised by aquarium players. It is easy to have a stress response when being frightened, and care should be taken to prevent jumping when feeding.

9—Light-lipped fish
Most of the streams in the south of our country are distributed, generally believe that this is a relatively fierce fish, its speed is very fast, and there is a situation of food grabbing. When polyculture, care should be taken not to raise fish that are too weak to be raised together.

It is found in ditches or streams between the plains of Chinese mainland and western Taiwan. One of the most common native freshwater fish in Hong Kong, but its population has also decreased in recent years. Like peacock fish, the male is smaller and brighter in color, and the female is larger.

Tropical fish prefer high temperatures, but there are also some species that can survive in low temperatures. Generally in the northern winter, there is a heated indoor, and it can safely overwinter without inserting a heating rod.
1— Blue Manlong, Yellow Manlong
The scientific name is filamentous hairy-footed perch, a tropical fish with strong adaptability, climbing perch fish have pleated gills, can live in water with low oxygen content, when the water body is hypoxic, can go to the surface of the water to swallow air, to ensure survival. Blue Manlong's temper is not particularly good, and caution should be exercised when polyculturing with small fish. The most suitable temperature of Blue Manlong is 22-28 ° C. It can survive for a long time at 14 °C; the lowest temperature for death is 11. 5℃。

2— Peacock fish
Peacock fish is the most common tropical ornamental fish, large and flowing fins, they also have a certain tolerance to low temperatures, 18 ° is a safe temperature, below this temperature Peacock fish body functions began to decline, can survive for a short time. 18 ° is still relatively easy to achieve for households with heating in the north.

Strong and mild-mannered, it can be polycultured with almost all small fish. After a long period of artificial breeding, the temperature adaptability is also getting stronger and stronger. Zebrafish survive at water temperatures of 11 to 15°C. The limit temperature is also around 6° and can also survive for a short time. It can be said that it is a very frost-resistant fish among tropical fish.

6—Miscellaneous seabream
The so-called hybrid seabream refers to several varieties of artificial large breeding in the Three Lakes cichlid, which is jokingly called the hybrid seabream because of its low price. They also have a certain tolerance to low temperatures, when I first started raising three lakes cichlids, the water temperature in winter was around 16 °, and the seabream were still alive and well, grabbing food like mad dogs.
