Summary. Hello, I am happy to answer for you, 1. If the breeder feeds a single food for a long time, the fish will get tired of eating and begin to refuse to eat. 2. When the fish is sick and unwell, they will refuse to eat and drink.
3. Fish that have just come to an environment will not eat due to their unfamiliarity and inadaptability to the environment. When the fish acclimatize to the new environment, they will resume eating. 4. If the new water is not replaced for a long time, the water quality environment in the fish tank will deteriorate, and the fish will refuse to eat.
5. The amount of fish diet will be different in different seasons and different weather. When the weather is hot or cold, the fish will also not eat for a short time, and when the temperature warms up, the living environment will warm up and the fish will start eating again.

The alligator gar is a type of gar.
It belongs to the genus of gars of the gar family, but the alligator gar is relatively large, and its body length can reach about 3 meters after adulthood.
Wild-grown alligator gars live mainly in freshwater, occasionally entering saltwater, and are relatively adaptable to water quality.
They are usually dark green or olive green in color, with grayish-white sides of the back and some parts of the belly that will be pink.
This fish belongs to exotic creatures, some are known as killers in the water, and have no natural predators. Alligator gar, a carnivorous fish, is highly destructive and has a very complex food. As long as it is a creature that lives in water, it can be its food.
This fish is very large, which not only destroys the ecology, but also causes the total number of freshwater fish to decline rapidly, and needs to be hunted in time.

There are no alligator gars in China.
There is no alligator gar in China, which is an invasive alien species and is extremely harmful. The most striking thing about the alligator gar is its tightly arranged, tooth-hard, ultra-hard enamel scales, also known as bony scales, which have a dark brown back and a mostly pale white belly.
The scales are hard enough for it to hide from many ferocious predators, so it doesn't have many predators, which is one of the reasons why the alligator gar can survive on Earth for so long!
The alligator gar has a cylindrical body, and the most distinctive feature is the mouth similar to that of a crocodile, hence the name "alligator gar". Its mouth protrudes forward, its upper and lower jaws have bony plates, and its long mouth is full of sharp teeth!
The alligator gar has its own unique way of breathing, in addition to the normal gill breathing, the alligator gar's swim bladder is covered with capillaries connected to the esophagus and can also be used to breathe with the swim bladder, even in the absence of oxygen, the swim bladder can also be used to obtain oxygen, so the alligator gar can survive on land for a short time. Alligator gars have a very long lifespan, most of them live for 26-50 years, and the longest can live for 75 years.
Breeding characteristics of alligator gars
The alligator gar can survive for 100 million years thanks to its reproductive characteristics, laying eggs from May to August every year, and laying 150,000-280,000 eggs at a time. The eggs are pale green, sticky, adhered to aquatic weeds or gravel, the incubation period is about 6-7 days, the hatching success rate is high, it is worth noting that the eggs are highly poisonous, and if other fish swallow them, they will also die.
Males reach sexual maturity around 6 years of age, while females reach up to 11 years. The alligator gar can grow up to 3 meters or even longer, weighing 45-72 kilograms, which is definitely the "freshwater fish overlord" among freshwater fish.

The alligator gar is an invasive species from the waters of North America, and the reason why it enters the country is because of the ornamental fish. For example, some people want to raise fish, but give up later, and now it appears in many places.
1. What kind of invasive organism is this?
This is actually a very ferocious freshwater fish, which belongs to the top of the current food chain, has a relatively strong reproductive ability, and has no natural predators, so it will cause devastating damage. Nowadays, people like to hunt for curiosity, always like to raise some fish that look very ugly or very **, after raising for a period of time, they feel that there is no fun, they will choose to release, this kind of release is a good thing, but I don't know that it will have a great impact.
2. What are the hazards of this invasive species?
The alligator gar is a very dangerous alien creature at present, and it causes many hidden dangers. First of all, eating everything will even lay a highly poisonous fish egg, which will destroy the ecological balance. It is an invasive organism with strong vitality, with a lifespan of more than 25 years, and can survive both saltwater and freshwater ecosystems, and can also breathe air.
Even if it is out of water, it can effectively survive for more than two hours, so it has long been considered an invasive alien species.
3. Where do they appear now?
According to the survey, alligator gars have appeared in many areas of Guangdong today. In addition, it is found in Shanxi, Fujian, Jiangxi, Guangxi, Jiangsu, Wenzhou, Hunan and other places. After investigation, experts found that the main reason for the appearance in the current market is a channel for ornamental fish, which are now widely reproduced throughout the country.
There are some people who choose to breed, but after a period of time and feel no interest, so they will choose to abandon, this kind of behavior, in fact, it is easy to cause many hidden dangers, and the later may cause a large number of reproduction, so it is recommended that you do not do this.
Can't eat. The alligator gar is a top poisonous fish, and like the pufferfish, it can produce highly toxic substances during ovulation, and people will be poisoned and even life-threatening after a few bites. Therefore, after catching this fish, the public should never eat it. >>>More
Alligator gars do not recognize their owners.
The number of pet crocodiles in the market is relatively limited, generally only Thai crocodiles, which can grow up to 3 to 4 meters and have a fierce personality. >>>More
Strengths. In ponds, small rivers, and small lakes, it is obvious that the alligator gar has a higher status and is the apex predator. >>>More
Each has its own strengths
In ponds, small rivers, and small lakes, it is obvious that the alligator gar has a higher status and is the apex predator. The adult great white shark is generally four meters long and weighs about 1,000 catties, while the adult alligator gar is 1 meter long and weighs about 50 catties. >>>More
The inclusion of alligator gar in the list of invasive alien species can effectively avoid the formation of alligator gar population in China and protect the ecological environment of China. >>>More
