Goldfish observation diary

(1) Goldfish is an ornamental fish that our people are happy to raise. It has become a natural and living work of art because of its peculiar posture and gorgeous colors, so it is loved by people. There are several small goldfish in my house. It is really pleasing to watch them play freely in the water in their spare time.

(2) Looking at the lovely little goldfish, I suddenly wanted to know their origin, so I opened the book and began a wonderful exploration of the world. Scientists found that goldfish originated from the common wild crucian carp in China. First, it changed from silver-gray wild crucian carp to red-yellow golden crucian carp, and then from red-yellow golden crucian carp to different varieties of goldfish after domestic rearing in different periods. As an ornamental fish, red crucian carp was recorded in China as early as the Jin Dynasty. Red and yellow crucian carp began to appear in the "release pond" in the Tang Dynasty, and golden crucian carp began to appear in the Song Dynasty. People began to raise goldfish in ponds, and goldfish appeared in two colors: white flowers and spots. In the Ming Dynasty, goldfish moved into a fish tank. It turns out that goldfish is a variation of wild crucian carp, and now it has become an ornamental fish.

(3) Knowing the origin of goldfish, I love it more. I quietly looked at it in the fish tank today and found its wonderful color. It turns out that the color of goldfish is mainly produced by many pigment skin cells in the dermis. There are only three color components of goldfish: black pigment cells, orange pigment cells and light blue reflective tissue. All these ingredients exist in wild crucian carp. The bright and changeable body color of domestic goldfish is only caused by the recombination and distribution of these three components, the change of intensity and density, or the disappearance of one, two or three of them. Sometimes, within a certain range, goldfish will change with the change of background. This is a special adaptation of fish to the living environment. No wonder goldfish have all kinds of colors, so that's it. I also know that living things have the ability to adapt to the environment.

Alas, today is really boring. I walked to the fish tank with the fresh feed I just bought and sprinkled a handful into it. Several fish scrambled to find food in the water. I was happy, sprinkled a few more, and then left happily. In the afternoon, my mother suddenly called me over. "What's the matter, Mom?" Oh, my God, what's going on? A little goldfish is dying, as if dying. "There is a way to feed goldfish. You fed too much, so the goldfish died; And some problems that should be paid attention to when buying feed. Fresh feed is nutritious, but it also contains a lot of pathogens and bacteria, so it is best to feed pellet feed. However, you should also feed less. Generally, feeding can make the fish finish in 3 ~ 5 minutes.

It's best not to feed more than three times a day, "my mother made it very clear, and I was secretly convinced." Is there any way to raise fish like me? "

(5) It's time to change the water for the fish today. I emptied all the original water in the bathtub and replaced it with new tap water. It seems that I take good care of the fish, but the problems still happen one after another. My fish has become "unsuitable for water", which makes me very anxious. I didn't know until I checked the information online. I made two big mistakes when delivering the goods. First, the problem of water quality was not considered. Untreated tap water is very harmful to fish. Secondly, if I change the water in the fish tank, the fish will not adapt. Why am I always so careless?

(6) People say that "goldfish are cold-water fish, and the lower the water temperature, the better". I changed the tap water to cold water with a lower temperature. I thought I should be all right, but something happened again-goldfish have strong cold resistance, but too low temperature will slow down the metabolism of fish and make them dislike eating and swimming, and they won't last long. It seems that water temperature is also a key issue. Not used to low water temperature. What about the high temperature? It turns out that it is not good to be too high. When the water temperature is high, the oxygen content in the water will decrease, and goldfish is a species that consumes more oxygen, which is also unreasonable. So pay attention to the oxygen content in the water. If there are many small fish in the tank, just buy an oxygen tank.

(7) Can you tell the sex of goldfish? Suddenly curious, I found the information. Male and female goldfish are mainly distinguished from the following aspects: the difference of body shape: male goldfish are generally slightly longer, while female goldfish are short and round. The abdomen of female fish is larger than that of male fish during spawning. The difference between tail stalks: the male fish is slightly thicker than the female fish. The difference between pectoral fins: careful observation shows that the male fish is slightly pointed and long, and the first fin thorn of pectoral fin is thicker and harder; The female fish is short and round, and the first fin of pectoral fin is not too hard. The difference between genitals: from the abdomen, the genitals of male fish are small, narrow and concave; Female fish genitals are large and slightly round, protruding outward. I looked at my fish, and it was easy to tell the male from the female by these methods.

(8) How do goldfish breed? Generally speaking, during the spawning period, the belly of the female fish is relatively large, and the belly of the male fish has not changed. However, it is not difficult to find that there are several small white spots on the hard bone spurs in front of the left and right front fins of the male fish, especially during the spawning period, but the female fish certainly does not. In addition, during the spawning period, the male always chases the female's ass. At this time, it's almost time to lay eggs. The pair of fish should be put in the fish tank alone, and more aquatic plants should be put in the tank, so that the fish eggs can attach to the aquatic plants, otherwise the fish eggs will sink to the bottom and be eaten by the fish. After laying eggs, the female fish should not be mixed with any male fish for the time being, so that it can have a full rest to protect the female fish. Put aquatic plants with fish eggs in a fish tank (preferably a crock) with fish water, and place them in the sun. The breeding season of goldfish is at the turn of spring and summer every year. The south of China is 1-2 months earlier than the north. The south lays eggs in March and April, and the north lays eggs from the end of April to the end of June. Goldfish generally lay eggs at maturity of 1 year, which means that 1 year can breed 1 generation. If the temperature is raised in winter and the feeding management is strengthened, goldfish can lay eggs in advance in cold winter when they are 7-8 months old, and they don't need to lay eggs until 1 year old (12 months old). Goldfish can lay eggs many times during the breeding season. Every two weeks 1 time, 2-3 times. Where it shines, small fish will appear in a month or so.

(9) Since goldfish is a variation of crucian carp, can it be hybridized? I found the answer. Theoretically, it is possible. Goldfish itself is bred by wild crucian carp. They are biologically different varieties of the same species. But in fact, goldfish and crucian carp are difficult to cross, because they have undergone great changes in appearance and living habits. When they are mixed together, crucian carp has obvious physiological advantages, and it is difficult to naturally pair fish with obvious differences in advantages. Theoretically speaking, artificial insemination of goldfish and crucian carp can achieve successful reproduction, but no one will do such a thing, because their offspring will neither look better than goldfish nor have the strong living ability of crucian carp, and neither of them will be excellent.

(10) Fish farming is indeed a science. Through my own personal experience, I have learned a lot. I hope you can observe as much as I do Observe more, discover more, discover more, and gain more. It feels good to gain knowledge!

Or the following one is not bad!

Number one: My goldfish?

There are several goldfish in my fish tank, some golden, some yellow and white, shining in the sun. ?

Goldfish is a rare ornamental fish. It is plump, docile and bright-colored, and it is called "Golden Fairy" and "Peony in Water". ?

? Goldfish is the most beautiful dancer in the water world. Some of them are playful and some are quiet. Goldfish are interesting to eat! As long as I sprinkle with insect powder, they will shake their tails and pectoral fins desperately and swim east and west. Then he opened his big round mouth and rushed to grab it. When they are full, they sink to the bottom and rest quietly. After a short rest, the goldfish shuttled back and forth cheerfully as usual. Cheeks open and close, spitting dew-like bubbles, as if whispering and chattering. This fish tank is like their warm home. They go up and down, turn left and right, and live freely. ?

Once, I forgot to feed them, and the goldfish swam all the way to the surface, with its mouth open, as if to say, "Little master, you were so careless that you forgot to feed us!" " " ?

Goldfish are timid. I remember once, I put my fish pocket in the water to play tricks on goldfish. They were all scared and huddled in a corner. When I left, they swam proudly again. But when the goldfish was angry, I picked up a goldfish with a fish pocket, and it struggled desperately and threw water on me until I let it go. ?

Watching goldfish in my spare time is a great pleasure for me. It makes me feel very happy and refreshed, but goldfish love cleanliness and need to change water frequently.

I like these happy little goldfish. ?

Chapter 2: How do goldfish live?

In order to observe goldfish, I bought three goldfish, one with bulging eyes and chubby body, like a little fat man; The other has orange stripes on the upper body, but the lower abdomen is white. The other fish is red all over. If you don't look carefully, you really think it's a mass of bright red blood. There is also a goldfish in colorful clothes, which looks like a small flower.

Goldfish swim with four things under their heads. When swimming, goldfish will keep swinging its tail. I find goldfish like to hide in the dark. ?

When it is hungry, I put a handful of goldfish's food, and they will scramble to eat it, regardless of the previous gentlemanly demeanor; But when it is not hungry, if you force it to feed, it will eat and spit it out, which will make you half dead, and no matter what it is doing, its eyes are always bulging. ?

Strange?

These days, goldfish always float to the surface to exhale, which makes me puzzled. Why do goldfish always float and breathe? Guess what? It's a real mystery. ?

At noon, shall I come? When I looked at the goldfish, I found that the goldfish in colorful clothes died, and I cried sadly. ?

Hunger strike?

The next day, I found that when I fed the fish, they wouldn't rush to eat like the sun, or even turn a blind eye to the food. ?

At noon, fish always have no appetite, which makes me feel very confused. I was fine yesterday, but I'm too worried to eat today. ?

I remember: Is it because they found a good friend missing? However, they were all very comfortable yesterday. I don't know if they didn't worry because they thought the little goldfish went out to play yesterday, but it's been so long. Why don't they put the fish back? ! ?

Alas, I can't guess at all. Who can understand fish language? Help me ask why it has become so worrying, but who in this world can understand the language of goldfish? ?

Mysterious?

I changed the water for the fish these days, and found that every time I changed the water, they would become fierce, as if they were afraid of being played by me, like that little goldfish. ?

They are dressed in golden yellow, and their eyes shine like black gems. When swimming, that tail flutters, just like a golden yellow ribbon fluttering in the wind! ?

These three little goldfish are really interesting! Other little goldfish spit bubbles, thinking it was food, and rushed up to eat it. Sometimes, when I feed them, they immediately turn over and swim backstroke, which makes me laugh! ?

I am so happy, because I have three lovely little goldfish to accompany me! ?

These three little goldfish in my family are called "apples", "pears" and "grapes". ?

? After dinner, my mother will do other things, and I will feed the little goldfish. Before coming to the fish tank, the little goldfish seems to meet a stranger and run away without a trace! I waited left and right, but I still didn't see the little goldfish come out I shook the fish food as if to say, "If you don't come out again, I'll leave!" " ?

The naughty little goldfish "Apple" came out! Then, "Pear" and "Grape" swam out with their big tails wagging! Bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang.

After finishing my homework today, I can't wait to rush to the fish tank to see how my little goldfish is doing! ?

? I found the little goldfish swimming heavily. It turns out that there is a "line" (its stool) hanging on their tails. When the little goldfish swims around, the "thread" floats around like a ribbon, which is very interesting. ?

After a while, I was surprised to find that the "line" was gone! I saw the "line" dancing in the water, just like several super paratroopers performing acrobatics in the air. At this time, I found that the little goldfish relaxed and swam faster. I was busy reading, but my mother asked me to read English, so I had to leave reluctantly. ?

I will often come to the little goldfish house to "play" in the future! ?

2012101October 28th? Friday? Weather: Rain? Mood: Happy?

After finishing my homework, I thought, "What will happen to the little goldfish today?" With this in mind, I'm going to meet my friends! ?

Before I came to the fish tank, I found them together, mouth to mouth, as if talking. I quietly walked over and they swam to their hiding place (under the oxygen bar) and started their "conversation" again. ?

I put the straw on a toy fish, put it down, stirred it, and the fish came around. As soon as I picked up the straws, they ran away I put the straw down again and their eyes were attracted by me again. In this way, I played games with them, and the more I played, the more energetic I became. I didn't stop until my mother called me. ?

? These three little goldfish are so cute and interesting! ?

"What's wrong with my little fish? Sleep? Play? Talk? " ? After finishing my homework, I thought about it. I still don't know what the little goldfish is doing, so I finally decided to have a look. ?

It turned out that the little goldfish was lying in the grass. I teased him with a stick, and the "apples" and "grapes" swam over, and the "pears" were still in the same place, motionless. I thought, "Is it sleeping or laying eggs …" What is it doing? I don't know. ?

I hope to see pears swimming happily tomorrow. If you are laying eggs, I hope to see more little goldfish appear soon. ?

Article 4: Goldfish "compete for peony"?

Today, as soon as Miss Zhao entered the classroom, she asked everyone, "What is a goldfish like?" Some students say goldfish is like a chubby elf, some students say goldfish is like a fairy in a flowered skirt, some students say goldfish is like a colorful submarine, and some students say goldfish is like a policeman in camouflage clothes?

? Just as we were talking, Teacher Zhao suddenly took out a bag of goldfish from behind. We cried in surprise: "Ah, goldfish!" " "At this time, Miss Zhao asked us to name the lovely little goldfish. We rushed to give our names. After teacher Zhao's selection, we decided to name this little black goldfish "Pearl Buck". Because "Pearl Buck" is black all over, only two big black eyes are exposed, so we call it "Pearl Buck"! The other fish head seems to be more beautiful than the blooming peony, so we call it "Sai Peony". I like "racing peony" best. Sai Peony's eyes are round and small, and they are squeezed on both sides of her head like a magician.

The cheeks of "Sai Peony" are well hidden! Hiding behind white scales, you can't see it without looking carefully.

Whenever "Sai Peony" lies quietly, its cheeks will open and close, which is really fun! It seems to say proudly, "Look how beautiful I am."

The scale of "Sai Peony" is the most beautiful in the world. The scales in the sun will turn silver, like wearing a shiny black joke! How dazzling!

"Sai Peony" has a round and bulging belly, which seems to contain a big watermelon. The tail of "Sai Peony" swings from side to side, swimming slowly for a while, and motionless for a while, as if closing its eyes. ?

I found "Sai Peony" sleeping with his eyes open and floating motionless in the middle of the water. At this time, other goldfish rampaged in the water, only "Sai Peony" remained motionless, as if the world was still. ?

I like little goldfish very much. I must buy goldfish next time. ?

Article 5: Little goldfish?

There are four lovely little goldfish in my fish tank. They swim freely in the fish tank every day. I like them very much. Three of them are red and one is white. They all have scissors-like tails, big eyes and toothless mouths. Seeing them swimming freely, I suddenly had a question: How do fish swim and breathe in the water? I quietly leaned against the fish tank and observed it carefully for fear of disturbing them. Finally, I found that when a fish swims, it first glides forward with the fins on its stomach, and then adjusts its direction with its tail. They breathe through their gills, and sometimes they spit out bubbles one by one in their mouths. When I fed them, they first touched them with their mouths, then immediately ate the food and swam away. Their eyes are still open when they sleep, because they have no eyelids, so they are sleepwalking! Little goldfish are really a lovely group, full of secrets waiting for us to explore and study when we grow up! ?

20 12 10 1? Thursday? How are you?

Today, my mother bought me three goldfish, all of which are beautiful. One is orange all over, with big eyes, as if it were protruding and falling. I named it "Little Orange". One is all black, with eyes like black beans and a tail like a tuxedo, so it is named "Black Boy". There is also a most special one. Its head is a little red, its whole body is white and its eyes are the smallest. I'll call it "Little Red". ?

I looked at these lovely goldfish carefully. They had four fins under their bellies, like rowing on a boat. They keep drinking water while swimming, and then use gills to filter and absorb oxygen, and occasionally float to the surface to breathe air, because it is sultry today, and there may not be enough oxygen in the water. ?

2012101October 2? Friday? How are you?

Mother forgot to buy fish food yesterday. I was afraid that the goldfish were hungry, so I threw a grain of rice, but they just circled around the rice and refused to eat it. I didn't expect these goldfish to be so picky about food. I remembered that there were many shrimps in the river, so I went to the river and fished some back. ?

I put a little shrimp first and ate it up immediately. So, I added a lot. After a while, I saw that the shrimp had almost eaten, and the bulging cheeks of the goldfish were also fat. I'm so happy. Is the goldfish going to have a baby? I asked my mother. Mother said anxiously, "Oh, no, the goldfish ate too much." Goldfish can't control themselves. What you give them, they eat, and the rest of the shrimp, they quickly dump. " I quickly changed the water for the goldfish. ?

Looking at those goldfish motionless, they must have been propped up. I regret it very much Why didn't I ask my mother earlier? ?

2012101October 3rd? Saturday? How are you?

When I got up early in the morning, I was sad to see "Xiaohong" dead. Mother said to change the water for the goldfish and throw away the dead. Dead goldfish will pollute the water source and affect the health of the remaining goldfish. With tears in my eyes, I carefully changed the water for the goldfish for fear that something would go wrong with them. Fortunately, "Black Boy" and "Little Orange" look healthier. ?

20 12 10 Sunday sunny?

Today, my cousin got married and went home after drinking the wedding banquet. It's past nine o'clock in the evening. I think goldfish should go to bed. ?

I went to see the goldfish quietly. Looking at the goldfish with their eyes open and motionless, I thought: Why don't these guys go to bed so late? So, I sang a lullaby gently. However, I waited for half an hour and didn't see any change in the goldfish. I was in a hurry, so I asked my mother. My mother said, "Your goldfish should be asleep. Fish have no eyes. " ?

Oh, I see: so fish sleep with their eyes open. ?

Article 7: goldfish continuous observation diary? Three?

My family has a beautiful big fish tank with many beautiful "Feng Shui fish". Maybe you will wonder, what is a "feng shui fish"? Let me tell you, the so-called "feng shui fish" is goldfish. ?

Will the weather be fine on Wednesday, September 22nd?

My goldfish look unusual, and I have given them many strange names, including "Bubble Eye". "Red Cherry Blossom", "Xiaojin" and so on. Some of them have black eyes like two black gems; Some people are covered with rows of golden scales, just like their colorful clothes; Others wear a big red cherry blossom on their heads, which is very beautiful. Goldfish are not only beautiful, but also can play wonderful "music". ? When they swim, their tails make a slight swish, as if to say, "Am I dancing beautifully?" When they spit bubbles, they will make a bang, "as if to say," I'm playing at a good speed! "They swim freely in the water, like dancing dancers, elegant and beautiful! ?

Will the weather be fine on Thursday, September 23rd?

I like feeding goldfish best. Feeding is very particular. You can't feed too much at a time, or the goldfish will die. I tried to put my fingers into the water, and they swam over quickly, trying to "eat" my fingers, feeling itchy! Probably hungry, I poured more fish food, and the little goldfish grabbed fish food in the water! Fish food is like brown pearls around a goldfish bowl, and some "pearls" are still floating on the water! I poked the "Pearl" with my hand, and the "Pearl" just fell into the artificial flower. The water in the water pipe kept pouring down, and all the fish food in the artificial flower floated up again. Some "pearls" also fell into the goldfish's mouth, which was so fun!

Will the weather be fine on Friday, September 24th?

Today, I put my finger into the fish tank again, but the little goldfish didn't wake up. I thought: Why don't goldfish fall for it? I took a closer look and found that every goldfish's belly was bulging, like a small table tennis ball. It turns out that this group of "gluttons" have long been fed by their fathers. They are still swimming leisurely in the water, playing with each other, and some will hide in the flowers and play hide and seek! Suddenly found an incredible thing. My black goldfish turned golden. I shouted, "Mom and Dad, come and see! The black goldfish in our house has turned golden! " I cried happily. Mom and dad came, and they were very happy at first sight! In this way, our family had a happy morning! ?

Is it sunny on June 65438+1 October1Friday?

Goldfish can be very naughty sometimes! Today, mother put the duckling made of wood in the fish tank. When Bubble Eye swam over, it knocked down the duckling. Mother had to help the duckling up again, but the naughty "Xiaojin" knocked the duckling down again. Mother patiently let the duckling stand up again, but soon, the duckling fell down again. This cycle? Finally, my mother waved her hand and said, "No, no, I'm too tired!" " "Do you think our goldfish is naughty? ?

65438+10.2? Sunny on Saturday?

? In the evening, it's time for goldfish to sleep. I knocked on the goldfish bowl and shouted, "Little fish, little fish, it's time for bed!" " "I called the little goldfish several times, but their eyes were still open. So I was curious and looked it up online. It turns out that the little goldfish sleeps with his eyes open, because the goldfish has no eyelids, but there is a film to protect his eyes from water. I whispered to the little fish, "Good night, little goldfish! " " ?

My goldfish brings me endless fun. I really like them! ?

Chapter 8: Little Goldfish?

There are several small goldfish in my home, and I often pay attention to them. ?

? Goldfish swam leisurely in the water, their eyes protruding, as if they were going to fall. Look, they are fat and wearing golden red dresses; The tail swings back and forth like a big fan. Sometimes the fish will stay in the corner. When I pull the water, they swim around in fear. ?

When the fish is hungry, as soon as they see people approaching, they will swim in the direction you are going. I threw a fish food in, and a fish poked its head out as if asking for my advice, so I nodded and the fish swallowed the fish food at once. It seems to feel that it is eating alone, so it swims to its partners and touches their mouths as if to say, "I'm sorry." I put some fish food down again, and the little goldfish jumped up and grabbed it like he hadn't eaten for ten years, stood up and opened his mouth wide, as if to swallow all the fish food into his stomach. ?

Goldfish is so cute. I like goldfish. Do you? If not, find out and raise it quickly! They will bring you a lot of fun.

Article 9: Interesting goldfish?

There are many small goldfish in my big fish tank. It really makes me happy to watch them swim carefree in the fish tank every day. ?

The most interesting thing is to feed the goldfish. I wish I could feed them several times a day. As a result, a few little guys, I don't know how hungry they are, all went to heaven to play. In order to play an "interactive" game with the little goldfish, I thought of a good way. Before I feed the fish, I have to knock on the wall of the fish tank three times before I can throw the fish food. After a long period of training, knocking on the cylinder three times has become the "assembly number" for goldfish to eat. ? As soon as the "assembly number" rang, the goldfish generally rushed at me, opened its jaws and stood upright, as if shouting, "I'm starving!" " Give me something to eat! "Some even stick their mouths out of the water and wait for food to fall directly into their mouths. After a long time, as long as the fish sees me walking in that direction, they will come at me like a sword, wagging their tails on my cradle and doing some dance moves that make people want to laugh. ?

Goldfish love to be clean. If they don't change the water every two days, they will protest collectively, stick their mouths out of the water and make a big noise to attract my attention. They seem to be gesturing to me: "little master, our house stinks, please clean it for us!" " Every time I see such a scene, I feel a little embarrassed, because I forgot to clean their home, so I put down what I was doing, brought the dried water and fished the goldfish one by one, but these naughty goldfish seemed to punish me for forgetting to change the water for them, jumping around in the fishing net, splashing and getting my face wet. Whenever I change water, I have to wipe my face with a towel. But it doesn't diminish my love for them at all. ?

Goldfish has brought endless happiness to my life and study. Whenever I am nervous or unhappy in my study, I play with my little goldfish. Sometimes I tie food with thread to tease them and make them jump up and down in a hurry. It's so cute. I have many interesting things with my goldfish. Do you also like these cute little goldfish? ?

Article 10: Cute little goldfish?

? Yesterday, there were two more "little guests" in my house. A goldfish is red and white, with a big tail and transparent color. It is beautiful when swimming. There is also a small goldfish, whose "bubble eyes" are very cute. From beginning to end, the whole body is white. ?

Goldfish sleep with their eyes open. Early in the morning, I got up to see my little goldfish. However, when I came to the fish tank, I found "red" and "white" motionless and their eyes protruding. I thought they were dead. But they didn't turn over. I asked my mother, "Mom, will goldfish die?" Mother smiled and said, "The goldfish is not dead, just sleeping. Because goldfish have a thin and transparent eyelid inside their eyes, they just close the thin eyelid when they sleep, so their eyes look like they are open and motionless. " Really? I moved the goldfish curiously. The goldfish was frightened and swam around in the fish tank. ?

Goldfish are also interesting to eat. I often feed goldfish. They are so cute. When they eat, they are still spitting bubbles! I thought: What do they eat besides fish feed? I consulted this book. It turns out that goldfish not only eat fish feed, but also eat young fry! My father caught some small fish from the river and put them in a fish tank. Goldfish think that they, like feed, will fall directly into their mouths. But they soon found that fry are different from feed because fry can swim. Goldfish rushed to fry like an arrow, and after a full meal, they were ready to catch the next target.

Ah! These two little goldfish are really cute. They brought great happiness to my childhood.
