and bear paws and fish
Childhood obsessive Jurassic, Dinosaur toys fill the drawers. Growing up obsessed with ancient fish, Butterflies swim into the fish tank.
Welcome friends back to this somewhat different fish viewing column, I am the one who has both the fish and the bear's paw.
Have you ever seen a dinosaur with your own eyes?
Haven't seen it?
I haven't seen it either!
However, just because humans haven't seen it with their own eyes doesn't mean that other animals haven't seen it.
At least the three-eyed dinosaur shrimp have been seen, at least the tardigrades have seen, at least some ornamental fish have seen.
Today, We will take stock of the ornamental fish that have witnessed the heyday of dinosaurs, they witnessed the prosperity of dinosaurs, and they witnessed the demise of dinosaurs.
They have a common name , ancient fish , also known as "living fossils in the water".
Students, please sit down and listen to the noise.

Coelacanth
Ancient fish appeared in the Paleozoic or Mesozoic, but are still alive on Earth.
The three words ancient fish are relatively unfamiliar in the aquarium circle, but you may have seen them.
For example, the famous Arowana, Red Arowana, and Silver Arowana all belong to ancient fish.
If you're an aquarist, you've probably heard of stingrays, anti-sky knives, and duck-billed sturgeon.
Even if you are blinded by all of these things, you must have heard of sharks, almost all shark species appeared on the earth earlier than dinosaurs, and those unlucky dinosaurs who accidentally fell on the seashore are likely to be chewed by sharks as afternoon tea.
By the way, as a qualified Chinese, you should also know about the "Chinese sturgeon".
In the world of animals, there is a wonderful category called "Arapaima".
More than half of the ancient fish are classified under this category. For example, the dental butterfly, the bony tongue fish, the humpback fish, the weevil fish family, the bare buttocks fish family, the Brazilian arapaidae and the lunar eye fish family.
In short, they are a group of fish with very good looks, and their retro shape will subvert your inherent understanding of the "fish" group.
According to the information collected by The Hatcher, there are currently fifteen species of fish that are clearly classified in the ancient fish sequence, and the Hatchers divide them into three categories according to their personal preferences.
The first category, too common boring class. 6 types.
Seeing these species of fish, it's almost hard to associate them with the mysterious Jurassic. Because they are so common!
They are: Arowana, Stingray, Anti-Sky Knife (also called Naked Buttocks), Duck-billed Sturgeon, Finches, sharks (such as the spotted heterodonted mackerel).
The second category, rarely buyable classes. 4 kinds.
These kinds of fish either live in the sea and cannot be caught; or they are all abroad and are almost invisible at home; or they are almost extinct, and some people dare to sell them, and you dare not buy them.
They are: lunar eye fish, hagfish, bichfish, coelacanth (see image above).
The third category, cute and cute. 5 kinds.
These kinds of fish can be bought, and they are also the most common ancient fish species in aquarist tanks, as long as you are willing to spend money, you can buy them.
They are: arapaima, lungfish, dinosaur fish (scientific name polyfin fish), bowfin fish, ancient butterflyfish.
The first type is too boring, the second type can't buy, and today we will focus on the third category, let friends walk into the fish tank, into the Jurassic.
Arapaima
Arapaima, also known as walrus fish, is 100% freshwater fish. As for which person with strange brain circuits gave it such a broken name, it is not known.
Among the many ornamental fish, the arapaima is the closest to the arowana.
However, it is much larger than the Arowana. Not only that, but it is also the largest freshwater fish on our planet, which can easily grow to more than two meters.
This big guy doesn't seem to belong to any protected animals in the place of origin, and in our country, as long as you want to buy, there is not much difficulty.
In short, if you want to raise it well, you'd better prepare a pond instead of a fish tank.
Arapaima appeared at least 100 million years ago.
It is not a very ferocious fish species, and even in the Jurassic Period, it is estimated that it has no chance to bully dinosaurs.
lungfish
Lungfish really don't have lungs, it just has a swim bladder that can be used as a lung.
That is to say, its swim bladder is evolving from a swim bladder to a lung, but without knowing why, it was slammed on the brakes by the Creator.
As a result, its fish maw has become an embarrassing organ that is "like a swim bladder instead of a swim bladder, like a lung instead of a lung".
However, because of this feature, lungfish can survive a long time without water, and it is said that they can sleep in the soil for 3 to 5 years.
That's why it's called "undead fish" by aquarists.
Lungfish appeared on Earth during the Devonian Period, earlier than the Jurassic period when dinosaurs flourished, and according to the data I have collected so far, it appeared 400 million years ago.
Lungfish have a strong sense of territory and are also very aggressive.
There are currently six common species of lungfish: Australian lungfish, Victorian lungfish, South American lungfish, outer gill lungfish, West African lungfish and wicker lungfish.
Friends who have watched the famous web drama "White Night Pursuit" must remember that the protagonist in the play raised a fish, that is, a lungfish.
Tabby dinosaur fish
The professional name of dinosaur fish should be "polyfin fish" because they have several dorsal fins.
This is probably the one that looks most like a dinosaur among the ornamental fish mentioned today.
It not only looks like a dinosaur, but also has been in close contact with dinosaurs, and is called "dinosaur fish", which is well deserved.
There are many species of dinosaur fish, and I have collected 13 species of pictures, of which my favorite is the "Tabby Dinosaur King" in the picture above.
According to the division of aquarists, dinosaur fish are divided into "king" and "non-king", one is large and the other is small.
One of them is called the "grass rope dinosaur", and its other name is the famous "reed eel".
Although the appearance of dinosaur fish is domineering, it is relatively docile to raise, and compared to rogue lungfish, dinosaur fish is already a well-behaved baby.
bowfin
Don't look at it like a food fish, but it is just an ornamental fish.
The bowfin fish is a species of fish that has played with dinosaurs and can grow up to nearly one meter.
Another name for bowfin fish is pike, but it is not a species with the pike in Heilongjiang, China.
The real wild bowfin fish currently exists only in the United States, and its biggest feature is that it is resistant to high temperatures, can breathe air directly, and can also sleep in summer.
In China, only many fossils of bowfin fish have been found, but there are no living bowfin fish.
There are not many ornamental fish players who play bowfin fish, but they are also available.
Ancient butterflyfish
Fish that can walk are not unusual, fish that can fly are quite rare. The ancient butterflyfish is one of them.
This is The Most Beloved Ancient Fish of the Bulge.
The ancient butterflyfish is not pretty, but it is personal enough and is a small freshwater fish suitable for the vast majority of players who are looking for an alternative.
The scientific name of the ancient butterflyfish was "toothed butterflyfish", which is also the only species of the tooth butterfly family.
The toothed butterfly fish can fly because its pectoral fin is unusually developed, allowing it to fly out of the water to catch small insects flying low on the surface of the water.
Probably because it is accustomed to being on top, the toothed butterfly fish will turn a blind eye to the fish food that has sunk to the bottom of the tank.
Because it can fly, when raising it, you need to cover the tank lid, otherwise the next day you will find your fish flying away.
Friends who have played with the tooth butterfly fish know that in fact, its head shape and body look quite like a dragon fish, but with two more perverted pectoral fins.
Yes, the toothed butterfly is also a distant relative of Arowana, and is a relative of Arowana who "can't climb high".
Please make up a picture of a tall dinosaur swaying in the water while roaring, a large group of toothed butterfly fish playing on its side, swimming over a giant arapaima at the bottom of the water, accidentally touching the savage lungfish, the lungfish spit out the anti-heaven knife in its mouth, chasing the passing dinosaur fish, who knows annoyed the big dinosaur, and then the big dinosaur reached into the water with both hands, grabbed a golden arowana in his left hand, grabbed a stingray in his right hand, and then threw two fish at the crocodile eel in the distance, which knew that it was thrown deflected, and smashed on the head of a bowfin fish. Such a picture, Hollywood screenwriters dare not dare to imagine, haha!
The words in the heart of the boy: I will share two knowledge points with you. First, the ancient warship fish does not belong to the ancient fish; second, some people say that the African pillow fish also belongs to the ancient fish, but according to the study of the hoo, it should not be an ancient fish, although it looks strange enough, but I really don't find its name in the ancient fish list.
The article is not easy to write, look forward to the tips of friends, and wish every good friend who tips on the good luck recently!
There may be only one gap between you and successful fish farming.
