Did the nine-horned dinosaur hibernate?
Dinosaurs can generally grow into large species and small species. Races include golden dinosaurs, green dinosaurs, spotted dinosaurs and other species whose body length is mostly less than 30CM; Big species refer to other species such as Tiger King, Golden King and Crocodile King. Except for the yellow turban dinosaur king, other fish don't grow so fast, so they can be raised for a period of time according to the breeding method of race.
Water tank: As all small fishes are less than 30CM in length, it is only necessary to ensure that the width of the fish tank is 30CM. If you raise 10CM young fish, you can use a 45CM fish tank; If the body length exceeds 25CM, it is best to use an aquarium with a size of 30*45*45.
If you raise a large dinosaur fish, you will definitely use a tank more than 60CM wide in the end. As for the length, it can range from 120CM to 180CM, but you must pay attention to the width of at least 60 cm. Because the size of dinosaur fish is often limited by the narrow width at the bottom of the sink, not to mention other fish tanks with a width less than 45CM, it should be avoided as much as possible. However, a species like the Yellow Scarf Dinosaur King, which likes to swim around in the aquarium, is less affected by the area limitation at the bottom of the sink, so the teacher has no such worry.

How many fish do you need to keep?
Dinosaur is a kind of fish that can be mixed in a fish tank. For example, 30 young fish with body length 10~ 15 cm can be put in a standard tank with a length of 60CM. Individuals over 25CM in length can be moved to a large aquarium of 120CM for polyculture. However, there is a problem. Farmers often can't control their desires. Instead, they buy small fish that look promising and put them in the culture tank to keep the fish tank full. If there are only dinosaur fish in the fish tank, even if the number is large enough to fill the bottom of the fish tank, there will be no problem. But why do so many fish end up in fish tanks? In addition to the lack of willpower to stop buying, from a biological point of view, preventing the fight between male fish and using the principle of competition to promote appetite are also the main reasons. Single feeding and multiple feeding will have different effects on their appetite and indirectly affect their growth and development. Generally speaking, peers will stimulate each other's appetite because of competitive factors. In addition, if two or three individuals are raised in the same fish tank, when they reach sexual maturity, males will often start to fight with each other (there will be fights between females, but not as fierce as males), but if the number of individuals is increased in the fish tank, the situation will be alleviated. Of course, the more fish there are, the more powerful the filtration system is needed.
filter
Generally speaking, the upper filtration not only has fewer problems, but also is more convenient to use. It is worth noting that there is often a gap between the upper filter motor and the water inlet, and some dinosaurs will drill out the cylinder from this gap. As for filter materials, commercially available products can usually be used; In addition, filtering materials such as coral sand can be added to buffer the risk of rapid acidification of water quality. When the number of fish increases or the size becomes larger, the water quality tends to deteriorate. At this time, it is not enough to use only the upper water filter. It is suggested that an auxiliary external water filter can be added, or a filter tank can be set at the bottom of the fish tank. At this time, filter cotton can also be installed at the water inlet of the external filter to absorb visible garbage as much as possible for thorough biological filtration, while the upper water filter can achieve the effect of physical filtration. Whether the filtration efficiency and system of the fish tank are sufficient can be judged by whether the pool water is always clear or whether the fish's eyes are blank after changing the water.
External factors affect the color of fish. Different fish like different water quality. But for dinosaur fish, their tolerance for water quality is quite high. If you change one-third of the water once a week, there should be no problem. If the water quality is poor because it is not changed for a long time, the fish's eyes will be turbid and the nasal tube will start to fester. Water must be changed as soon as possible at this time. When the water quality deteriorates, it is also possible that the fish in the fish tank are still alive, but once the live bait such as Zhu is put in, it will die immediately. Although water quality has no absolute influence on the survival of fish, it plays a very important role. White light, black sand and alkaline water can cause small fish species. To put it simply, if you put big sand on the bottom of the fish tank, use white solar tubes, put coral sand, spotted dinosaurs and other fish in the filter tank, and the green dinosaurs and twisted dinosaurs will be more vivid if they are raised in acidic water; If you put them in weak alkaline water, the whiteness of your body will disappear. But the body color of fish is different according to personal preference. It is suggested that you use different lights, bottom sand and water quality to experiment your favorite fish color. At the beginning of building a tank, it is suggested to put sand at the bottom of the tank first, because they are not only related to the stability of water quality, but also dinosaur fish don't like the bottom of the tank to be too smooth; In addition, this fish has the habit of drilling into the sand. You can spread it with fine river sand and enjoy observing its habits. The type of bottom sand depends on personal preference. As for soil and sand, it will make the water turbid, which is not suitable for active fish species and large fish. It is better to avoid it as much as possible.
Change water
Basically, even if the old water is pumped and replaced, adding tap water directly will not have any impact on the dinosaur fish. However, considering that the water quality of tap water will change due to the season or after heavy rain, especially after the rain, the dosage of disinfectant in tap water is higher, so it is safer to add some commercially available water quality stabilizers when adding water. A 60CM aquarium and a plastic bucket are enough to reserve the wages that need to be replaced; If it is a large fish tank, it is recommended to use a bucket with a capacity of about 80 liters to lift water.
water temperature
In fact, you don't have to worry too much about the water temperature. Usually, you just need to keep the water temperature around 26 degrees, but if you want the fish to grow up quickly, you can turn up the water temperature a little. However, who asked? Rapid change is dangerous. These dinosaur fish can accept a slow rise and fall at a water temperature of 15 ~~28 degrees. In addition, when using the heater, we should pay attention to the problem of scalding fish. Because the dinosaur fish feels dull, it is easy to burn once it is close to the heater; If all scales are lost, there is no hope of regeneration. In order to avoid this situation, it is suggested to add a protective cover to the heater. Try to avoid putting the heater at the bottom of the fish tank. It is safer to fix it at a place twice as high as the fish.
fodder
The most suitable bait for small dinosaur fish should be wheat worms. Because most of the fish known as small fish species feed on insects or crustaceans in the natural environment, the skills of catching small fish are not very clever; So they like to eat this live bait, and its slender body is easy to swallow. As for the common bread worm, it lacks nutrition and is difficult to digest. Individuals with the size of 15 cm can forcibly swallow like ordinary breadworms, while smaller individuals should feed smaller breadworms. It is suggested that the above two kinds of bait should be given priority to, and if combined with artificial feed, Antarctic shrimp, Zhu, etc., it can provide balanced nutrition. Basically, in the larval stage, give as much bait as you can eat and feed it every day. As for large fish such as the king of golden dinosaurs, it is obvious that they are more interested in small fish than insects, even though Zhu is the staple food. However, if the King of Golden Dinosaur and the King of Crocodile Dinosaur are mixed, the King of Crocodile Dinosaur who is waiting in ambush will often get no feed. At this time, you can put more bait, and it is best to fill the bottom of the tank.
Mixed culture with other fish species: dinosaur fish is a fairly standard benthic fish. Most of the time, they like to crawl at the bottom of the bathtub and rest until there is food, so most of the time the water in the upper layer of the fish tank is quite empty. In order to make up for the emptiness of the upper floor, it is also good to put some other fish. For example, Arowana, Tiger Tiger, Three Swords of Crown, Dark Cloud, Silver Plate, Toothfish, Fierce Fish and other large Gallasin are all good collocation species in the upper waters. Dinosaur fish is an incredible fish, they will avoid eating the same kind, so there will be no big problem in polyculture between the same species. But for Lei Long, who is similar in size, attacks often occur. Generally speaking, dinosaur fish will not attack species wider than their mouths, but it is best not to put them with pleco or corydoras. I don't know why, dinosaur fish like hard things very much, and often make catfish erect their pectoral fins for defense because of swallowing or strong collision, which leads to both losses. In addition, alien species will bully dinosaur fish, although there are successful examples of polyculture (I am O(∩_∩)O haha ~), but basically I still try to avoid it.
Diseases and Precautions of Dinosaur Fish: Dinosaur fish is not easy to get sick, especially the most susceptible fish-white spot disease, which is not common in them (I seem to have met J unfortunately), so we just need to pay special attention to accidents, injuries and parasites when raising.
Jump cylinder
Small species often jump out of the cracks in the aquarium, and large species will bump into lights or lids. If you jump out of the fish tank, even if you look a little dry, the fish will recover as long as you put it back in the sink, so don't give up. If it happens, put some yellow powder in the tank to avoid secondary infection.
Nasal tube injury
When it hits the cylinder wall or the water quality deteriorates, the dinosaur's nose tube probably won't disappear but will curl. In this case, it is recommended to cut off the part and let it regenerate.
Dorsal fin bending
Mainly caused by malnutrition in childhood, but also caused by impact. You can use scissors to subtract the bent part and let it regenerate.
White eyes
It may be caused by wear or deterioration of water quality. You can change the water first and then add yellow powder to improve it. It can cause blindness for a long time.
Lily (brown lily ii variety. Viridulum Baker), also known as Qiangshu, Fanjiu, Shandan, Daoxian, Chongmai, Atrium, Moluo, Xiang Chong, Zhong Fenghua, Lily Garlic, Master Garlic, Garlic Brain Potato, Cordate telosma, etc. , a perennial herbaceous bulbous plant of Liliaceae, is native to Lilium. In recent years, artificial hybridization has produced many new varieties, such as Asian lily, perfume lily and fire lily. Bulbs are rich in starch, which can be eaten or used as medicine.

Perennial herb, plant height 70~ 150 cm. Bulbs are spherical, pale white, and the top is often rosette-shaped, which is formed by polymerization of most fleshy egg-shaped scales.
Roots are divided into fleshy roots and fibrous roots.
There are dozens of fleshy roots called "bottom fillers", which are distributed in the soil layer with a depth of 45~50 cm and have strong water absorption capacity.
Don't die every other year. Fibrous roots are called "upper packaging" and "adventitious roots", which occur late and begin to occur when the stems germinate on the ground for about 15 days and the seedling height is greater than 10 cm.
It is slender in shape, with the number of 180, distributed in the surface layer of soil, and has the functions of fixing and supporting the aboveground stems and absorbing nutrients. Dies with the stem every year. There are bulbs and stems on the ground.
The stems are erect, cylindrical, often with purple spots, hairless and green. Some varieties (such as Lilium lancifolium and Lilium psammophila) can produce "pearl buds" between axillary leaves of aboveground stems; Some can grow "seed balls" on the stems of the buried parts.
Beads and bulbs can be used for reproduction. The total number of leaves can exceed 100, alternate, sessile, lanceolate to elliptic-lanceolate, entire, with curved veins. Some varieties of leaves are directly inserted into the soil, and a few will form small bulbs and develop into new individuals.
The flowers are large, white and funnel-shaped, and are solitary at the top of the stem. Capsule ovoid, obtuse.
Seeds numerous, ovate, flat. It germinates in early June, starts to blossom in early July, blooms in mid-July and ends in late July. The fruiting period is from July to 10. [ 1]
