It can grow up to 17cm in the wild, but it is usually less than that big in aquarium. Most of them sold on the market are about 5cm. Freshwater fish, high hardness water pH8. O, suitable for water temperature 24-28, non-toxic. Submarines usually have a lighter body color when they sleep or rest.

morphological character

The body is small, round and bloated, with a large abdomen. A pair of protruding eyes are very vivid and clumsy when swimming. The fish's body is bright yellow green with black or green spots on it. Its appearance is simple and honest, and its appearance is very lovely. Swimming with pectoral fins, more funny. When fishnet is used to pick up, air will enter the swim bladder, and the belly of the fish will expand like a ball. The adult fish is 15 cm long.

habit

1. It can be raised in fresh water and properly salted in the water. The fish has sharp teeth and will attack other small fish. When it comes to bigger fish or danger, its body will expand to scare off the enemy.

2. Although he is small, he can take care of other people's fins. He especially likes to bite other fish and even his companion's tail fins.

3. Submarine fish have the habit of reproductive migration, which is vicious and timid. When the living environment is bad (such as lack of bait and high breeding density), they often kill each other, especially in the stage of seedling cultivation. The special structure of the esophagus makes the submarine fish inhale air and water when encountering enemies or being frightened, which makes the chest and abdomen expand like a ball. The skin spines stand up and float on the surface of the water to pretend to be dead, so as to defend themselves. When it is safe, the submarine fish can quickly discharge the air and water in the chest and abdomen and swim away quickly. In addition, it also has the habit of biting teeth, and will make a "Goo Goo" sound after being arrested.

toxicity

Golden giant salamander is a kind of puffer fish. The skin, muscle, viscera, blood and eggs of puffer fish are highly toxic. It will be fatal if you eat 10g of it. According to experts, most puffer fish belong to toxic fish, and the toxicity of its toxin is 1250 times that of highly toxic drug sodium cyanide. It only takes 0.48 mg to kill people. If the submarine fish is raised as an ornamental fish, special care should be taken to avoid direct contact with the fish when there is a wound on the hand (but most of the fish on the market have been artificially bred for a long time, and their toxicity has weakened or become non-toxic).

varieties

Golden Doll is an ornamental fish of the family ambrosidae on the domestic market, which can be called spot green puffer. Among many kinds of ornamental fish, the finless porpoise is one of the special species. Many people know nothing about them. Usually, when people find them in the aquarium shop, it's hard for them to resist the temptation: sweet and lovely face, clever and constantly trembling fins, round body. But a few weeks after buying them, problems followed. Those lovely little guys are no longer as lively as before. They hide or crawl under the water. The small fins on the fat body are no longer flapping. These fins droop listlessly. The bright body color in the past has gradually become dim. The scene of wolfing down in the past can no longer be seen. The sad blue eyes are watching the master, but the master is often helpless.

In fact, dolphin ornamental fish often have some special requirements, the owners should study the needs of these small things, and establish a suitable environment for them to meet their requirements. There are many kinds of ambrosidae ornamental fish in fresh and salt water, and about 300 species have been found. They range in size from 2.5cm to 66cm. Most of the finless porpoises need 30 liters of water for every 3cm long, according to the length of the fish. If your little one is 6cm long, it needs at least 60 liters of water. For the common green black spotted puffer in the domestic market (submarine, deep-water bomb, Golden Doll, etc.), because of its small size, it does not need to calculate according to the above method.

Reproductive characteristics

Golden baby chooses the fish about 7 cm in length as its parent. It is difficult to distinguish between male and female fish at ordinary times, but the body color of male fish in estrus period is more gorgeous than that of female fish, and the caudal fin is pointed in the center of the outer edge of the caudal fin; while the caudal fin of female fish is still round, and the dorsal fin and gluteal fin are round and blunt. The body length and size of male and female are similar, but the abdomen of female is enlarged. The water temperature of spawning box should be kept at 25-26 ℃, the water quality should be slightly acidic, the concentration of hydrogen ion should be 158.5-199.5 nmol / L (pH 6.7-6.8), and the hardness should be 6-7 degrees. One female can lay more than 100 eggs, and then take out the parent fish. The hatching period of fertilized eggs is longer, and it takes about 12 days to hatch larvae. The larvae can feed on the live baits such as the fleas and the fleas.

Feeding points

1. Keep constant water temperature (about 24-28 ℃) and pH value. Water to add some salt or half of the proportion of artificial seawater.

2. Try to reduce its pressure, which will damage its immune system and make it easy to get sick. It is a good choice to arrange something for it to hide in the tank, such as wide leafed aquatic plants, rocks, caves and sunken trees.

3. Don't feed too much, if too much, it may cause constipation. Just feed it once or twice a day.

4. Filtration and water flow are also essential, but the water flow should be slow. Filter system must not add activated carbon, should put filter cotton and coral sand.

5. As Golden Doll is more aggressive, it is better not to mix with other fish.

6. Check its physical condition regularly. Every day to carefully look at its body, to see if there are external diseases, parasites, bacteria, fungal infections, bite marks and other injuries. By the way, watch its activity to see if it's abnormal.

Pressure line

Golden Doll appeared pressure line how to do?

1. Disinfect the fish tank before use (brush it with high concentration potassium permanganate water, and then soak it in low concentration potassium permanganate water for about one day)

2. It's also very important to choose fish. Sometimes the fish you choose to go home already get sick.

3. When you take the new fish home, you should pay attention to that the water temperature in your fish tank has reached the temperature suitable for your small fish to grow (your fish is more suitable at 27 degrees plus or minus 1 degrees, which is not an absolute value). Don't open the bag, put the bag into the fish tank together, float for 10 to 20 minutes, then pour the fish into the tank again, and don't feed it for three days. Then feed the fish twice a day, with the small fish in each time It's best to eat in five minutes.

4. Change the water. If there is no filter oxygen system, change about one-fifth of the water every day. If there is filter oxygen system, change about one-third or one-half of the water every three days. Pay attention not to use the tap water just connected. After the tap water is connected, it is better to put it on for two or three days, and then change it for the fish. Because tap water contains a lot of harmful substances to fish. Another is to pay attention to the control of water temperature when changing water. The water temperature of fresh water and the water in the original tank should not be less than plus or minus 1 degree.

5. Pay attention to the oxygen consumption of small fish. If there are more fish, you have to increase the oxygen pump to pump oxygen.

6. When the fish got sick, they went to the fish shop in time to consult about the medication. (consult a few more, one is to increase experience, the other is to prevent being cheated.)

Secondly, there may be the following reasons for the pressure line:

1. I'm scared.

2. The water quality and temperature are not well controlled (as mentioned above, the water quality is mainly maintained through water exchange and water maintenance. Take a closer look at the "water exchange" link mentioned above).

3. Sick.

4. Due to the change of environment, it takes several kinds of time to adapt.

Symptoms of disease

1. Bad appetite. If you find that it has a bad appetite or is picky when eating, it is a problem. 2. Pressure line. It is also a bad sign to find dark gray lines on the side of its body between its back and abdomen, which can extend from its mouth to its tail.

3. For the type of white belly, if its belly turns black, and the color continues to deepen, it is necessary to pay attention to.

4. The color of the back gradually becomes dim, and for a long time can not change the normal body color, is also one of the dangerous signals.

If problems are found, it is necessary to carefully check its living environment (salinity, temperature, filtration, pH value, ammonia and nitrite concentration, etc.) and whether it is threatened or physically attacked by other fish.
