Only one warship fish can be kept in a 60 cm aquarium. You can put a warship, a crown and a scavenger. Stay at four. If there are too many, your jar will look small.
Is it okay to raise arhats in a fish tank of 80? The following is for reference.
The size of arhat fish tank is generally subject to the growth and development requirements of fish. If economic conditions permit, the bigger the fish tank, the better. This will bring you a lot of convenience in the future. In addition, it is suggested to use a covered fish tank, which can prevent fish from escaping from the fish tank because of fright, and also prevent dust and debris from falling into the fish tank. If you want to raise a healthy arhat fish, you must start with a fish tank.
If the arhat fish is kept in a narrow space from an early age, it will not only grow slowly, grow short and thin, have a dull color, but also be inactive, and may become a "dwarf fish". Under normal circumstances, Lohan can grow to 20~30cm, so the fish tank needs at least 100cm*50cm*50cm (length * width * height), the bigger the better, which will give Lohan a room for development, not only growing fast, but also better body color.
Can Brazil only keep one? Mix what,
First of all, it depends on whether your filtration system can withstand so many fish.
I suggest you mix Brazil instead of rainbow fish.
Don't mix Brazil with rainbow fish.
As for thick lines, it doesn't matter if you mix a few casually.
It is impossible to keep only one female dragon.
If you want to raise sharks, how to raise them ~ ~ ~ I suggest not to raise marine fish for the time being. First take a jar with a length of 1.5 meters, a width of 60 meters and a height of 60 meters (water level). However, there are three or four Genghis Khan sharks, and some places are called great white sharks. Different places have different names, but they are all similar.
This kind of fish is easy to identify, similar to the little blue shark, and some places are called tiger sharks. I suggest you know all about it in Baidu.
The difference between the two is that the former gives people a sense of shock in the atmosphere, while the latter is a little stingy.
The former is suitable for large tanks, and the latter only needs a tank of about one meter, which is easy to distinguish. The former, whether it is each fin or the fish itself, is much stronger and more atmospheric than the former.
Hehe, having said so much, I suggest you go to Baidu first and take a photo before making a decision.
It is not recommended that you drink seawater. The cost is too high. Even if you are at the seaside and the sea water is readily available, it is not for ordinary people to play, unless you are a rich man with a monthly income of over 10,000 or even 10,000. ......
Of course, if you are rich, I can also introduce some to you.
Spotted shark, this kind of shark has great personality and belongs to bottom fish. Hehe, again, go to Baidu and look at the map. Maybe you will like it.
Fox mackerel, this shark is very similar to the shark in my memory, but don't worry, although they are scary, they don't bite, but they just have room to raise them ... It is estimated that the length needs 10 meter and the width needs about 5 meters. This shark doesn't bite, really, but its tail can't be used by people!
High-fin white-eyed shark: This shark can be said to be overbearing. All the fins are telling you,' I am a shark!' , coupled with the towering dorsal fin, but also let a person have a feeling of convulsions.
Sawtooth shark: ... This shark is too overbearing, as sharp as the teeth of a saw. I believe that if it falls into your cultural jar, it will definitely experience what is called ... death.
Horn shark: a kind of marine shark suitable for breeding, but generally it is not difficult to raise.
By the way, at present, the mainstream sharks of seawater lovers are gray sharks and white-fin sharks, and the price is only the price of a golden dragon. Hehe, it's not expensive, just the maintenance fee ... at least I can't afford it.
Is it okay to keep a dragon fish and two tiger fish? That's how I keep them. The only thing to pay attention to is the size. Moreover, spades' mouths are quite cheap, and they will chew the fins, but if the arowana is big, it is estimated that it will not dare.
A small water snake died before, and now I want to raise another one. Is it Geely? Wild snakes are hard to raise and may die in the end. You'd better not keep them, lest you hurt a little life.
My tank is 80 cm. Can I just eat a fat fish? About the rich fish, it's just that people give it a nice name. Fish farming itself will waste water, electricity, nutrition, medicine and installation fees for it. Fish farming is just out of interest, and there are not many other purposes. If your purpose is not correct, then the result must be wrong. It is very likely that you can't raise the fish well and raise the fish to death. Calm down and take care of it slowly, just because you like it. For the number of fish, it depends on your fish tank. Don't blindly pursue quantity, give the fish a room to grow. Another reason is that there are too many fish, too much density, poor hygiene, and the water quality is easy to change, which is very harmful to fish! Choose carefully!
How to raise a small crucian carp has four kinds of moisture: first, fresh water, that is, tap water that has just been aired or well water that has been drilled recently. Although this kind of water is clean, it is very different from the environment in which fish live in nature. Because there is no nitrifying bacteria community in the water, fish excreta and scattered food residues decompose into ammonia after corruption, and fish are easy to be poisoned. Second, the old water, light green or amber, is rich in humus and beneficial microorganisms and algae, and has established a good ecological circulation system. After nitrogen is recovered, it is decomposed into nitrate which is harmless to fish. This kind of water is extremely beneficial to the growth of fish. The third is green water. There are too many organic substances in the water, and cyanobacteria, green algae and brown algae multiply in large numbers, and the content of bacteria and microorganisms increases sharply. The water is thick green, and sometimes it smells bad, which can easily lead to the death of the whole tank of fish. The fourth is to return to clear water, also called biting clear water. It is because there are too many algae and microorganisms in the green water, which consumes the oxygen in the aquarium, causing the death of algae and aerobic bacteria, and turning the water into stagnant water without oxygen and a large number of anaerobic harmful bacteria.
It can be seen that not all water is suitable for goldfish's life, and the most suitable water for goldfish's growth is old water. Hydroponics is the process of changing new water into old water.
At present, most of the water we use for fish farming is tap water, so the first step of water cultivation is to remove the toxic substance-chlorine from tap water. The method of chlorine removal is relatively simple. After the water is filled, let it stand for 2-3 days, or dry it 1 day (in case of urgent need, add 0.5% per 100 kg of water). 63g of baking soda, namely sodium thiosulfate, can be used immediately).
After the fresh water is dried, it should be put into a tank for filtration, so that the water pump can turn the still water into flowing water, and then put the fish into the tank. "Broken tank" is to put a few cheap, strong and easy-to-raise fish into a new tank. After a few days, fish excrement will be decomposed into ammonia in water, which is the same as adding ammonia to tap water. Too much ammonia will kill fish, so the most important thing to raise water is to remove ammonia from the water. Usually we use nitrifying bacteria to remove ammonia from water. Nitrifying bacteria can be added to water, but they need attachments to survive in water. If there is no suitable attachment, it is not good to add more nitrifying bacteria. They will die in water, and nitrifying bacteria usually attach to filter cotton or bottom sand. In fact, running water will naturally produce nitrifying bacteria in a few days, which is also the most commonly used method to cultivate nitrifying bacteria. The cultivation of nitrifying bacteria is the second step of hydroponics.
Let's briefly introduce the subtle chemical changes of nitrogen cycle and see how nitrifying bacteria work.
After the fish enters the tank, it will discharge ammonia and other wastes into the water, and the ammonia concentration in the water will increase, so the nitrifying bacteria in the domestic water can decompose ammonia (note: it takes a week or more for nitrifying bacteria to form, so the fish will be seriously injured during this time). When the nitrifying bacteria community is formed, the ammonia concentration will be reduced to zero.
However, it is not that simple, because nitrifying bacteria can only convert ammonia into nitrite, but it is also toxic to fish! So we should understand that the concentration of nitrite is increasing, while the concentration of ammonia is decreasing. So don't think that you can sit back and relax after the ecology is established. In order to reduce nitrite, it is necessary to change water regularly and quantitatively to reduce its concentration, so as to maintain a relatively stable ecology and keep the water in an old state.
Pay attention to the stability of water when changing water, and don't differ by 3 degrees!
I also want to tell you that old water is what we pursue, and green water also has many benefits for goldfish. For example, green water can darken the color of goldfish, but there are too many algae in this water to see fish and it is not suitable for viewing. Moreover, when there are too many algae, the fish will lack oxygen, so we should pay attention to controlling the algae content in the water when raising goldfish with green water.
Scavengers can, tropical fish can't! Koi fish is a large ornamental fish!
First, diligent observation and early treatment.
Generally, after fish are infected or attacked by pathogens, there will be some signs for a period of time. For example, sick fish move slowly and often swim slowly on the water without gathering. If they are disturbed, they will surface after a little sinking. There are also some fish that swim wildly when they are just sick, or they are gray and scaly. For another example, after the bleeding of white crucian carp, the wild small miscellaneous fish in the early fish pond died. When fish disease symptoms are found in fish ponds, measures should be taken in time to prevent the disease package from expanding.
