Fish are ectothermic aquatic vertebrates that are covered with bony scales, breathe through gills, swim through the swing of the tail and trunk and the coordinated action of the fins, and feed with the upper and lower jaws. The following is what I have collected I hope this essay describing fish will be helpful to you! Chapter 1: My family’s fish
My family has a fish called “Arhat”.
When my father first brought it back, I thought it was for cooking, because it was already as big as an adult’s hand, and it looked like a "Fu Shou" fish. Dad said: "It is not for eating, it is a tropical ornamental fish." I asked: "Why is the "Arhat" raised last time different from this "Arhat"?" Dad said: "Because they are different species." This fish is much more beautiful than the last one, with most of its body It is red, only its belly and tail are gray, and its eyes are round and a little bulging. The mouth is large and flat, with sharp teeth.
"Arhat" has very high requirements for water quality and water temperature. If it is raised well, a swollen "big bag" will grow on the top of its head, which looks a bit like the head of Shouxiangong from the side. That's why he was named "Arhat". When it first arrived at our house, it was unfamiliar to us and did not dare to eat. After a few days, it began to eat a lot. If we forgot to feed it, it would hit the fish tank hard. It has a really big appetite. Originally, it could only eat about 8 pieces of fish food in one meal, but when we saw that it wasn't full, we fed it more and it was still able to finish it. Later we discovered that it only grew a body but not a brain. Our purpose was to let it eat the "big bag" on its head.
It has very high requirements for water quality. The more it eats, the more it poops. In a few days, the water becomes yellow and looks dirty, so it takes about ten days to change it. After changing the water once, it will become red all over and will not eat until the next day. Sometimes when our family goes out to play and doesn't see us for a few days, it will be unhappy, its body will turn white, and it won't eat. When we come back, it will be happy again.
It also likes to play with people. If you put your hand on the fish tank, it will swim along your hand. If you put your face on the fish tank to fight with it, it will suddenly bump into it. , will shock you.
This fish has been kept in our home for more than a year. Although it has not yet grown up, we still like it very much. Chapter 2: My Guppy
On my coffee table, there is a large rectangular fish tank. There are two fake aquatic plants at the bottom of the fish tank, surrounded by colorful and various pebbles. In this elegant and comfortable environment, a group of cute guppies live freely.
These guppies are so beautiful. The male guppy is the most beautiful. It has a slender body and a big and wide tail. It is exactly the same as a peacock’s tail. I think this is why it got its name! The head of the guppy is transparent, and its two eyes are black and shiny, like two black gems. From the head to the back, it gradually turns yellow, then turns to cyan, and the back of the body turns to dark purple. The most interesting thing is the color of its tail. The background color of the tail is light red, and the outside is covered with colorful patterns, which are colorful and unpredictable.
When it is still, it looks like a neon light flashing. When it swims, its tail swings from side to side, like a fairy dancing gently with its brocade skirt. Looking at this gorgeous guppy fish, it is really amazing. Under the careful care of my father and I, the guppies gradually grew up. Later, the female guppy's abdomen swelled and black spots appeared on her buttocks. Dad told me it was going to give birth to small fish. Dad fished out the female fish and put her in a small fish tank to feed her alone.
One night, I was doing my homework, and suddenly I heard my father calling me. I went over and took a look, and it turned out that the female fish had begun to give birth to small fish. I stared at it curiously. It swam slowly, trying not to turn around, for fear of hurting the little fish, but also as if to comfort itself. Suddenly, its belly began to shake, and then, a small bright spot swayed out of the fish's buttocks. When it almost fell to the bottom of the tank, the small bright spot spread out and started swimming quickly. This is how the first life was born.
This discovery made me understand: There are many mysteries in nature. I will definitely study hard in the future to gain rich knowledge and reveal them. Chapter 5: Guppies
I have six beautiful guppies at home, and I like them very much.
Guppies are very beautiful, with a variety of bright colors such as sky blue, golden, emerald green, light pink, bright red, etc. Therefore, guppies are also called rainbow fish.
Guppy has a very big characteristic, that is, it is greedy. As soon as you feed it fish and insects, it will not care about anything. Once I wanted to test it to prove that it is greedy. I sprinkled some fish worms into the fishing net, and he dared to go into the fishing net and eat them. It was beyond people's imagination.
One day, I came to feed my guppies again, and suddenly I saw several small black guppies less than five millimeters long swimming in the fish basin. It turned out to be the yellow tail. The female guppy was giving birth to baby fish, and I jumped up with joy. After another half an hour, she gave birth to baby fish. I hurriedly moved a fish tank with water, fished the baby fish in, and counted them*** Twenty items.
I observed the little guppies from the side of the fish tank. Those little guys looked very interesting. They were very different from their parents. The backs of the little fishes were gray and their bodies were transparent. Less than five millimeters long, the eyes are like small black dots.
The next day, I fed the small fish some egg yolk powder in small amounts, and they ate very enthusiastically.
A few days later, I found the guppy floating on the water after giving birth. It died. I was very sad and thought: How could such a well-raised guppy die?
One day, I went to my good friend Congcong’s house to read a book. I saw a book on tropical fish breeding in the book box. I quickly took it out to read the catalog, and then turned to the article about guppies. Mainly, guppies have always been considered to be a fish with extremely strong vitality, but after investigation, they are considered to be very short-lived fish, with a maximum lifespan of less than one year. Therefore, the life of a guppy is short but beautiful. life. Chapter 6: Small tropical fish
There are many beautiful small tropical fish in my fish tank. They are so interesting.
The body of male tropical fish is spindle-shaped, slender, and small and exquisite. Their belly is almost invisible, like a swimming champion, wearing a bright swimsuit. Female fish are crystal clear and large in size. They are usually dark brown in color. They look cute and clumsy. They all look like a pregnant woman wearing a dark coat. The front end of the tropical fish has a small mouth and small black pearl eyes. The fish body has colorful scales and fins. Some of the scales are red, some are silver, some are gray, and some are light purple. In the sun, They sparkled in the light.
There is a beautiful big tail on the back of the fish, and the red tail is like a red flag "fluttering in the water". The black tail is like a banana fan, constantly fanning the "wind" to make the water not so hot. The big black and red tail looks like a peacock opening its tail. Tropical fish swim freely in the clear water. When they are still, their tails swing constantly, like neon lights flashing. When they swim, their tails swing from side to side, like fairies gently dancing in their beautiful colorful skirts.
My favorite thing is to feed them. I put a larger piece of food into the fish tank, and the thirty fish rushed in from all directions like arrows, because the food was a bit big and their mouths were too small. So you take a bite and I take a bite. The fish that has eaten the food shakes its head and tail, as if to say: "It smells so good!" The fish that has not eaten the food bumps against the butt of the fish that has eaten, as if to say: "I'm so angry." , I hit." I looked at them and my stomach hurt from laughing. They looked like a group of children playing football.
There are so many stories between me and the little tropical fish. However, after my hard work, two tropical fish gave birth to more than 20 little tropical fish each. I also thought they were tadpoles in my fish tank.
Seeing them swimming carefree makes me feel very accomplished. I really hope they grow up quickly! Chapter 7: Little Goldfish
Recently, our family has added a few more little family members. They are three cute little goldfish living in the fish tank. They are Black Armor, Red Girl and White Sloth.
Among them, my favorite is the dark black armor. It has a jet-black armor, so I named it "Black Armor". It has a pair of big dark eyes on its head, and a small and exquisite mouth that keeps drinking water, making its belly bulging, as if to prove that the prime minister's belly can hold a boat. Maybe it is The prime minister among the fish tribe. There are four small tail fins behind its butt, which together form two large tails, which look like a pair of black scissors.
My black armor is not only cute, but also very naughty! It swam very fast at first, as if it were a courier with some urgent letter to send to the chief. Later, when it felt exhausted, it took a leisurely walk in the water like an old man and blew bubbles in the water from time to time. It was so naughty. Every time I go to feed them, the three little cuties are rushing to grab the food, but every time they are snatched away by the black armor. Relying on its own strength, it pushes the other two goldfish away and pulls the food away. All the fish food was eaten. I had to feed the other two goldfish while it was taking a nap. Black Armor is really a naughty and domineering goldfish!
But the good times did not last long, and I found that these three little cuties were getting more and more tired. My mother told me that goldfish can only swim in this small space every day, and they lack freedom. I reluctantly released them into the creek in the park. As soon as they entered the water, they swam happily around. I watched them and felt happy. Chapter 8: Tropical fish in my family
I have several tropical fish in my family. They have different colors and shapes. They are so beautiful!
Among these fish, there is one called the Red Arrow that I particularly like because it is red all over, with a streamlined body and a long pointed tail, like an arrow. There is also a fish with a swallow-like tail. It has a flat body, small eyes, and swims like a gentleman. It is a swallow fish...
Once I thought Watching them eat, I sprinkled a handful of fish food into the fish tank. As soon as I sprinkled it, they swarmed up. You squeeze me and I squeeze you to eat. The red arrow is the most ferocious. As long as there is a fish in front of it, It bit and chased it, and the little fish was scared by it and ran around. However, it scared the fish away, and the fish swam over to eat again, so it chased the fish again, and chased it back and forth. On the contrary, I couldn't eat anything. Maybe it was tired of chasing, maybe it understood that chasing like this was not a problem, so it started to occupy it. It circled around the fish food while eating, and then swam aside until it was full.
I heard from my father that fish are very timid. I wanted to give it a try, so I patted the glass on the fish tank with my hand. It was amazing. These little fish were running around, and some He hit the surrounding glass and almost fainted. Some hid in the corners of the fish tank and did not dare to move. Others hid under the water plants and peeked out secretly. What's particularly interesting is that Red Arrow and Swallow collided, causing a war. The red arrow bit the swallow's wing with its mouth. The swallow fought back like a bull and hit the red arrow with its head. The fight was very fierce and unstoppable. The other small fish were no longer afraid, and carefully swam out from their hiding places to watch. Just when they were fighting inextricably, I patted the glass again, and they quickly separated and hid.
My fish is fun! I like my fish very much.
