List of fish that can be mixed with arhat fish
Arowana
Generally speaking, there are fewer players who choose to raise Luohan and Arowana together, mainly because these two kinds of ornamental fish are more territorial and aggressive, and fighting will occur after mixed breeding, and it is usually Luohan's attack that causes Arowana to be injured. This is easy to cause related arowana diseases, and it does not improve the aesthetics of the fish tank, which can be described as both losses.
However, a small number of players successfully mixed Luohan and Arowana, giving a positive answer. If you must choose to mix arowana and arowana, then it is recommended to choose arowana as big as arowana, or arowana is bigger than arowana, so as not to hurt arowana by Lohan. In addition, in the early stage of polyculture, arowana and arowana should be separated by glass in the same tank to see if they can live in peace. if
Parrot fish
Hybrid parrots and arhats belong to hybrid fish and have a bad temper. If you raise them together from childhood, the problem is not big, and the size difference is more than one third, then it should be considered according to the size of the fish tank and the setting of the landscape in the tank. Usually parrot fish are sandbags for arhat fish.
Pignose turtle
Podocarpus heterophilus can be mixed with pig-nosed turtles, but it is more troublesome, because Podocarpus heterophilus is overbearing by nature, and the result of polyculture is often that pig-nosed turtles are bitten, and some even bite off their tails. Mixed culture of the two is a test of farmers' level.
Map fish
The polyculture of arhat and map fish is basically not polyculture. They are all fierce fish, and their regional concepts are very strong, so they can't be tolerated. Uninvited guests? Even if they are all arhat fish, it is better to raise them separately, especially at the stage of sexual formation, and fighting is inevitable, as is the map fish, so it is better to raise them separately.
Sweeper/sweeper
Podocarpus and scavengers can be mixed and raised together. Scavengers belong to benthic fish. They can eat by eating moss and food scraps, and can be fed with the same feed as arhats. Of course, taking arhat's feed as the main feed can only guarantee the basic living conditions of scavengers. If you want scavengers to grow bigger, you can also feed them some special feed suitable for scavengers.
How to raise arhat fish
Bait species
Lohan's bait is divided into natural bait and artificial compound feed, and natural bait is divided into live bait and dead bait. Generally speaking, Lohan is interested in live bait, which can increase Lohan's hunting and activity. However, the live bait contains many parasites and bacteria, which can easily make Lohan sick, and Lohan can easily bump into his body when catching the live bait. Therefore, when feeding live bait, clean it first, disinfect it with ultraviolet rays before feeding, squeeze it out and throw it into the water, so that the fish can eat more easily and avoid injury.
In order to reduce the harm of live bait to Lohan, it is usually possible to directly freeze live bait and then feed it to Lohan. It is safer to kill parasites and bacteria on live bait by freezing at low temperature. At present, there are many kinds of artificial feed on the market, and the quality is uneven. It is recommended that you buy brand feed produced by regular manufacturers, which is of guaranteed quality and beneficial to Luohan's health.
Bait feeding method
What method should be used to cultivate arhat? Four decisions? Feeding method, this method is conducive to the cultivation of good living habits of Lohan, but also good for its health.
1, timing: it means that the feeding time and interval should be fixed every time, so that Lohan can form good eating habits and reduce the occurrence of digestive tract diseases. Generally, it should be fed 2~3 times a day, and the feeding time should not be too long. Lohan had better eat it in 10 minutes. Feeding time should be adjusted according to season, temperature and climate. For example, in low-pressure weather conditions, feeding times and feeding time can be relatively reduced.
2. Fixed point: that is, the position of each bait should be fixed. After a long time, Lohan will get into the habit of eating food at a fixed feeding time every day, and Lohan will take the initiative to wait for the owner to feed, which is very interesting.
3. Qualitative: It refers to ensuring that the quality of bait is fresh and nutritious, and it is not allowed to feed spoiled or expired bait. If possible, the bait can be sterilized by ultraviolet rays.
4. Quantification: It means that the feeding amount should be relatively fixed, neither too much nor too little. Generally, the feeding amount is 65438+ 0~2% of Lohan's weight, and the feeding amount should be determined according to Lohan's size, feeding situation and seasonal changes. Don't feed too much at a time, and let the fish finish in 10 minutes. Pay attention to Lohan's reaction when feeding, and stop feeding when Lohan's appetite drops.
Water quality of raising arhats
1, chroma: refers to the color and transparency of water. It is best that the water body for cultivating arhat is colorless and transparent without turbidity.
2. Temperature: Lohan is most suitable for living in water with a water temperature of 26~30℃, with 28℃ as the best temperature. In the process of breeding, we must avoid sudden changes in temperature. If the temperature difference exceeds? 2℃, then the fish will get sick because they don't adapt.
3. dissolved oxygen: refers to the amount of oxygen dissolved in water, expressed in D.O., and the unit is mg/L. DO in Luohan water is normal at 5 ~ 7 mg/L. Too low will affect the metabolism of Luohan. Because of the large discharge of arhat, it is easy to cause the deterioration of water quality and make the water anoxic, so it is necessary to use an air pump to oxygenate the water and keep the dissolved oxygen in the water sufficient. Pay more attention to observation at ordinary times. If Luohan is found to have a floating head or shortness of breath, it means that the dissolved oxygen in the water is too low, and measures should be taken to increase oxygen in time.
4. Hardness: Hardness is generally expressed in KH, with soft water below KH7 and hard water above KH7. The hardness of water is related to pH value. The higher the pH value, the higher the hardness of water. When the pH value is low, the hardness of water is low, but there is no absolute conversion relationship between them. Generally speaking, Lohan likes neutral hard water. If you want to adjust the hardness of water, you can adjust the pH of water.
5. PH value: The pH value of water is expressed by pH value ... The pH value ranges from 0~ 14, with pH7 being neutral, acidic water below pH7 and alkaline water above pH7. Lohan is suitable for living in water with pH 6.5 ~ 7.2, and can also live in water with pH 6 ~ 7.8, but beyond this range, its growth will be affected. If the pH value in water is high, phosphoric acid, heavy wood, soft water resin, etc. The pH value can be lowered slowly. If the pH value is too low, coral sand can be added to slowly increase the pH value.
6. Ammonia nitrogen, nitrite and nitrate: Ammonia nitrogen is a chemical substance harmful to organisms, and too high a content will cause biological death. Ammonia nitrogen is the product of protein decomposition, and the excreta of fish and other organisms, such as urea and feces, will produce ammonia nitrogen; The decomposition of residual bait and dead fish in fish tanks will also produce ammonia and nitrogen. When Arhat is cultured, the ammonia nitrogen content in water should be controlled below 0.1mg/L. Nitrite is the product of primary oxidation of ammonia nitrogen, and it is also toxic to fish and other organisms. When raising arhat, the content of nitrite in water should be controlled below 0.1mg/L. Nitrate is the final product of ammonia nitrogen oxidation, which has no direct harm to fish and other organisms, but excessive accumulation will lead to water quality aging, harmful bacteria and algae proliferation and ecological imbalance. When cultivating Luohan, the nitrate content in water should generally be controlled below 30 mg/L.
Daily management of arhat fish
The daily management of ornamental fish is complicated, but it is also regular. Generally speaking, daily management mainly includes feeding, observing fish activities, monitoring and regulating water quality. Due to the different varieties, specifications and living habits of breeding objects, the requirements and standards for daily management are also different. What is the genus of Lohan in tropical ornamental fish? Noble? Among them, it needs careful maintenance. Pay special attention to the following aspects in daily management:
1, pay special attention to water quality monitoring.
Lohan is an ornamental fish, which requires high water quality. Due to a large amount of intake and excretion of arhat fish, it is easy to cause the deterioration of water quality. It is necessary to observe the situation of aquaculture water every day and find that the water temperature and color are abnormal and the water body is turbid, and corresponding measures should be taken in time. If conditions permit, it is best to check the indexes of water body every day, and master and adjust the changes of PH value, ammonia nitrogen content, dissolved oxygen and other indexes in time according to the requirements of arhat culture.
2. Pay attention to the activities of fish.
The activity of fish reflects the adaptability of fish to the environment and its own health. Observing the activities of fish is also a daily work, mainly to observe the intake of food and the swimming state. When the fish moves normally, press? Four decisions? Feeding in principle; If you find abnormal reactions such as not taking the initiative to eat or swimming weakness, you should check the water quality in time to check whether the fish are sick. You should find the problem as soon as possible, find the reason quickly and solve it in time.
3. Pay attention to the regulation of water quality.
Changing water is a necessary measure to ensure the quality of aquaculture. Pay attention to the following points when changing water:
(1) Dry in fresh water. The purified tap water is relatively clean, stable in water quality and convenient to use. Nowadays, ornamental fish are generally raised with tap water. Because tap water is disinfected with bleaching powder, there is free chlorine in the water, which will cause harm to fish. Before changing water, it must be dried to allow chlorine gas to fully volatilize. Another function of sunbathing is to reduce the temperature difference between fresh water and aquarium water and avoid the discomfort caused by the change of water temperature.
② Regularly and quantitatively change water. Different strains and specifications of arhat fish have different requirements for water quality, so the frequency of changing water for different fish is different. For example, Lohan, a pearl strain, likes fresh water, so the frequency of changing water is high, once every 3~4 days; Jinhua Lohan prefers to live in older water, so it can be changed every 10 day. Red horse likes to live in old water, so it only needs to change water once every half month. Water exchange is divided into partial water exchange and total water exchange. Generally, 30% of the total water in the fish tank can be partially changed, and some new water can be added as appropriate according to the prosperity of the water in the fish tank at ordinary times.
③ Master the skills of changing water. Changing water requires not only replacing some old water, but also cleaning impurities in water and removing pollution sources. Generally, when changing water, the water circulation equipment should be turned off, the water in the tank should stop flowing, and the water should be kept in a static state, so that all the feces and foreign bodies in the bottom sand can be removed. Control the speed of adding new water, slowly but not too fast. Fourth, add a new waterside and observe the reflection of Lohan at close range. If you find Lohan? Coward, your head? In case of discomfort such as dull body color, stop adding water immediately, and continue adding water after the symptoms of arhat discomfort are relieved.
④ Strengthen inspection and maintenance. Strengthening the inspection and maintenance of supporting equipment, whether the supporting equipment runs normally or not, is directly related to the quality of water, thus affecting the growth of Lohan. Therefore, in addition to checking whether the fish tank leaks water and whether the filter and water pump work normally every day, it is more important to maintain these devices frequently to ensure their operating efficiency. For example, the filter screen should be cleaned regularly to avoid reducing the filtration efficiency due to excessive dirt accumulation; Clean the water inlet of the pump in time to ensure the smooth flow of water.
