Ph value: pH value: 6.5-7.2.

1, it is best to set a tank with a height of 1 meter for raising arhats, which is beneficial to control water quality and make fish beautiful; 2. A good and powerful biological filtration system, with coral sand as the filter material to improve the hardness of water, and coral sand is also a rare good filter material; 3, regular quantitative feeding, less feeding, try to feed artificial feed, feeding live food is easy to infect and send inside; 4. Put some parrots as sandbags; 5. Adding a little salt to the water and changing the water frequently is said to stimulate the rapid growth of fish.

Has always been a parrot farmer. I also learned some arhats like this. My practice is to mix a few small arhats with parrots. Now, two one-meter cylinders are customized, with side filters. Add a partition, put some rain flower stones in the tank, and put the raised arhats separately. 1 Change water regularly, twice a week. The water is sleepy. Feed Luohan feed to ensure that you can't get sick from your mouth. 3 Turn on the light for 4 hours every day except normal light. I still believe that coral can promote the beginning of Lohan. Besides ceramic rings, coral is put in the filter tank.

Arhat is a kind of fish that is quite easy to raise. It has excellent ability and is not too picky about the living environment. However, it is necessary to pay attention to some small details when raising fish to keep the fish and water tank in the best condition. > Zb^KZ

1. Aquarium: Arhat is over 20cm in size, belongs to medium and large cichlids, and has a strong concept of territory. It is suggested that it is appropriate to raise it in an aquarium alone. In addition, the size of the space will also affect the growth speed and body shape of Arhat, so it is best to choose an aquarium above 1m when raising it, so as not to limit the growth of the fish. Taking black or blue as the background of the aquarium helps the arhat to present the most beautiful body color. .

2. Bottom sand: Arhat likes neutral or slightly acidic water quality. It is best to use river sand with a particle size of about 0.5- 1cm as the bottom sand to keep the water quality neutral, and the bottom sand can be spread to a thickness of about 5cm. The layout of the water tank should avoid using heavy wood or coarse stones to prevent fish from accidentally injuring the scales. \h)aI

3. Water quality: No matter what kind of fish is raised, good water quality is a very important part. Arhat is not strict with water quality, but because of its large food intake, it is necessary to choose a filter with good effect when raising, which can not only keep the water clean, increase dissolved oxygen in the water, but also help the growth of beneficial bacteria to maintain stable water quality. The water temperature is about 26-27℃; The pH value is between 6.5 and 7.2. WG

4. Feed: You can use raw bait: shrimp, red worm, etc. and feed without artificial pigment. %m

5. Lighting: Most tropical fish are kept outdoors in small ponds when they are in artificial farms. Due to long-term exposure to sunlight, their colors are very bright. When aquarium lovers bring tropical fish home to raise them, if they don't provide proper lighting for them, the color of their bodies will gradually decline. It is suggested that the daily lighting can be controlled about 10 hour, which will have a bonus effect on the health of fish and the performance of color picking. 7} In addition, because Arhat is a strong person, as long as the water quality is maintained well and the nutrition is paid attention to, it is difficult to have a chance of disease. In fact, arhat is not as good as fish traders and books say. It is rare to have a head shape and good color, which is about11000 or less. The fishmongers said, "Make sure to start with color!" You can't believe it! The fish you see in the shop is very bright in color, which is because of eating the coloring pigment. It won't be long before it will be Cinderella from "Flower Fairy =", and the fish merchants must say it is your water quality or feed problem. In a word, your fish will never change back to its previous color. Generally, the internal organs of fish that have eaten pigments will be damaged, and light fish will grow slowly (fading is of course); Heavy fish will die. There are many reasons for "eating color". The biggest reason is: eager for success, fish are fed with feed casually, and if the color is not good, they are "fed" (that is, eating color).

There must be many problems when you buy such fish back. My fish farm is generally fed with small fish and shrimps (note: shrimps are generally not fed during the fry period, and are only given when the fish grow to 15-20 cm, otherwise the small fish will only grow in color and not meat.

Received an email asking about the breeding and selection of arhat fish? In fact, arhat fish is very easy to raise! As long as the water quality is not seriously deteriorated (fishy and smelly), there is generally no problem. Our practice is: 1. circulating water-the stolen goods can be pumped out in time. 2. Accurate feeding amount-too much water pollution, too little fish and not enough to eat, usually the fish belly is slightly larger than usual. 3. Use coral sand as a filter-I heard that coral sand is rich in calcium, which can make the arhat fish start (you can try it). The function here is to improve the pH of the water so that it will not deteriorate. 4. Increase the amount of light-fish with proper light every day will have brighter colors. As for the fish feed, it has already been said above, so I won't describe it here. Everyone has his own standards for the selection of arhat fish. Personally, I think: the mouth should be short, the fish body should be wide and the color should be distinct (of course, "eating color" is another matter. ) The fish selected in this way will not look bad even if its head is not very big, because its mouth is short and its body is wide.

Nowadays, many friends buy small fish, which is not expensive for one thing, and there is no "eating color" for another. However, many fish farms are randomly paired, and the fry produced will look good when they grow up, depending on your luck! ! !

What is coral sand or broken coral?

Prevention and treatment of diseases of arhat fish: arhat fish is in good health and generally does not get sick. The most common ones are: 1. White spot disease.

Symptoms: At first, the fish will flip over against the bottom of the fish tank or rub against the hard ornaments. Later, one or two small white spots appear on the fish, and then the small white spots spread all over the body and even on the eyes. At this time, the fish generally don't eat and hide in a corner.

Cause: infected with white spot bug. (1) Generally, newly bought fish are put into a fish tank and infected without disinfection procedures; (2) The live fish (Zhu Wenjin) used for feeding has white spot worms, so it is best to put it in the refrigerator and freeze it overnight, and then thaw it the next day before feeding.

Treatment: 1. Use concentrated salt water (the concentration is suitable for drinking with bitter taste. Ha ha! ! Stupid! ! ) Wipe the fish. Pick up the fish with a net, put it on an appropriate plate with a thick cloth bottom, and rub off the small white spots on the fish with cotton dipped in salt water according to the fish. Note that salt water cannot enter the gills. Once a day, until there is no more. This method is only suitable for fish that don't want to put medicine into the jar and the infection is not serious. 2. Use mercurochrome (mercuric bromide-drugstore 0.50 yuan/bottle), and use one bottle for 100cm*45cm*60cm. It is necessary to circulate water and pump air, and the time depends on the fish's reaction: if the fish is hiding in a corner, it is necessary to change half of the water or all of it. On the contrary, you can change it one day. This method can not only get rid of the white spot bug on the fish, but also kill the white spot bug hiding in the water to prevent reinfection.

2. Rotten meat (collectively)

1. Symptoms

At first, there are small mildew spots on the fish, and then the mildew spots gradually expand, sometimes several at the same time, and the fish will slowly stop eating until they die.

2. Reason: Fish are infected with mold (collectively).

3. Treatment: Long-term medicinal bath with furantoin (the concentration is appropriate for fish to be active as usual), or oxytetracycline can be added to feed.

3. Severe sores 1. Symptoms: There are pus cells in the fish body, and white bands flow out from the cell tip when it matures. 2. Treatment: When the cell is mature, cover the pustule with a straw (the nozzle is larger than the pustule), and repeat the operation until the pus inside is sucked dry. Then put a few potassium permanganate into the pustule, and it is best to add oxytetracycline to prevent infection.

Prevention: Note that the newly bought live feed must be disinfected first, and a few oxytetracycline tablets (depending on the amount of feed) can be bathed for half an hour. In this way, it can not only sterilize but also kill insects, then put it in the refrigerator for quick freezing and feed it the next day. Don't give fish spoiled feed.

Treatment: 1. White spot disease: You can also put half a bottle of mercurochrome into a bucket filled with water that can submerge the fish's back, put the fish in the bucket for a medicinal bath for 5 minutes (depending on the fish's situation), then wipe off the dead insects on the fish with cotton and put them back into the fish tank. Do it again every 4-5 days until it is gone. 2. Rotten meat: You can also apply rotten meat repeatedly with red syrup until there is no slippery feeling in the rotten meat position, more than once a day, remember to be patient (not a day or two).

Note: Don't put drugs in a fish tank that is fine, especially antibiotics (oxytetracycline, etc.), because it will kill the digestive bacteria in the filtration system and make the water quality worse.

Usage of coral sand: Just received an E-MAIL saying, "She keeps a crock of colorful, and saw my post saying,' Coral sand can prevent the water quality from getting worse'. I went to buy it and put it in the fish tank. As a result, within two days, Qicai was all dead and called me a liar. " In fact, her fish died unjustly, and I was also scolded unjustly! ! ! ! Coral sand is rich in calcium, which can make water alkaline and neutralize acid in water. So it can stabilize the water quality. However, the higher the concentration of calcium ion, the higher the hardness of water, and the adaptability of arhat fish is high, so it can be filtered with coral sand. The colorful immortals like slightly acidic and low-hardness water (soft water), so it is not necessary to filter with coral sand. Therefore, fish farming should not only listen to other people's opinions, but also combine its own situation.

There are two ways to raise colorful water (slightly acidic): 1. If you are raising fish in bare tanks, you can circulate the water and change it as little as possible. After a long time, the water will become slightly acidic, and colorful prefers old water. 2. If grass is raised, it will be the best. Rotten leaves don't need to be taken away and let them rot in the water, so that the water quality is similar to that of their original place. My experience is on the line, believe it or not, it's up to you! ! haha ...........

Species of Loarhat: Today, Loarhat has a wide variety. What kind of "pearl arhat", "golden arhat", "one-stop" and "golden Buddha" are there, and the prices are not the same. If you want to say which one is good, it's hard to say, as the saying goes, "radish and cabbage, each has his own love." It's good as long as you like it, right? Let's talk from the experience of our farm (this is the secret of arhat farm): the arhat fish without beads, such as "Fuxing" and "Golden Buddha" on the market now, are the first generation of fish species, with monotonous colors but wide body, head shape and momentum, which I prefer; "Pearl" and "dragon" have beads and compound flowers, which look like presbyopia, but the head shape is smaller. I have seen fish species in several fish farms, all of which are only the size of the palm of your hand, so you can imagine how long the hatched seedlings can grow. Of course, there must be some good ones, depending on your luck. If you want to buy arhat fish, you'd better not shop in the wholesale market (those sold in bags). Many of them are "trash fish", "colored fish" and the female fish are sold as male fish. In short, it's a lie and no discussion! ! As for those famous specialty stores, I heard that all of them are imported, but our "Fuxing" big fish and fry are supplied to some stores (although our market is not big).

In short, the fish market is full of swindlers. As long as you look at it, he will blow the beautiful sow into a beauty. After buying it back, it won't be long before that beauty becomes an east beauty. If you want to buy a big fish, you should see that the fish should be wide in shape, bright in color, commensurate with the size of the eyes and the spirit of the fish. To buy a small fish, it is necessary to see that the mouth of the fish is short (the distance between the forehead and the mouth is short, and the mouth is long enough to form a right angle, so don't buy it, don't think it is a head, but it is actually a deformed fish); Don't have too big eyes (small face and big eyes). This is an "old man's head" that has been raised for a long time, but the color is very good; The fish should be wide, and the long ones don't look imposing (each has his own love). According to these conditions and your wisdom, you should be able to buy your favorite arhat fish, and of course, you need your support.

It's good to raise arhats and plant aquatic plants. Arhats have the habit of playing with sand, so aquatic plants must be started by him.

Podocarpus prefers to dig sand, and everyone likes to put sand in the tank, which can cause a headache. One solution is to change the original upper filtration to bottom filtration. You just need to buy a set of bottom filtration guy (a row of pipes with a filter screen, probably in 50 yuan, mine is made by myself) at the bottom of the tank, put the filter screen on it, then connect the water pump and the pipe, and finally lay it. My tank has been eight months old, and the water is still so clear. Just add some water occasionally to replenish the evaporated ones. In addition, the arhat fish prefers to dig holes, and the paved sand is dug up in a short time. I'm too lazy to pave it. Anyway, it's a waste of effort. It's better to let it be _ arhats can't be raised together. They can be said to have old fights when they meet each other, ranging from multiple injuries to heavy injuries. Moreover, the males of Lohan are very colorful and beautiful. They are very popular in recent years. And they are very spiritual fish. They can establish good feelings with their owners. I think this may be the main reason why Lohan is popular in the city ~ ~ ~ Think about it, a fish is as attractive as your puppy ... Can you not be tempted by it ~ ~ ~ ~ Speaking of female fish, its beauty is much worse than that of males, in fact. Generally, you don't have a mother fish ~ ~ ` You can buy a special feed for Lohan, preferably containing vitamins, or feed it with frozen blood worms and dried shrimps. If you want to feed small fish, you should first raise them separately for a period of time, disinfect them with potassium permanganate and then pinch them out when they are put into the water, so that the fish can be eaten more easily, and the collision of the fish can be reduced. The amount of each meal should not be too much, and it is better to be 70% full, and the belly can be slightly swollen. Time is based on eating within 3-5 minutes.

There are three fatal diseases of Luohan fish: 1. Exophthalmos and rotten meat. The reason is that the small fish (Zhu Wenjin) used for feeding is fed with antibiotics since childhood. If the fish is eaten too much, it will appear exophthalmos and rotten body. After getting sick, it can't be saved. Even if it is saved, it will be disabled and lose its ornamental effect.

2. Headhole disease: The reason is probably malnutrition, and the feed formula is monotonous, resulting in the lack of certain elements. Therefore, it is best to diversify the feed. If you have time, you can order hamburgers (just like colorful immortals) to try to keep the nutritional balance.

I hope it can help you ~
