The tank used to have koi fish, but now I plan to replace it with a silver dragon and a parrot, how

Your tank is too dirty, if you want to raise those guys to give you some advice, first of all, the tank is cleaned, there is no need to decorate the tank, you put away those various snail shells, re-open the tank, disinfect first, you should understand, and then raise water, the water temperature is 28 for three days to put the grass goldfish into the tank, before you dead fish is because the density is too large, and the filtration can not keep up with the cause, after a month, the parrot must not exceed three, the most one of the silver dragon, this is the limit, plus the absolute dead fish, Tropical fish are so expensive that you can't afford to die, and your tank to raise silver dragons is small, really small. You don't see the filtration I don't know what it is, it is estimated that it is the kind of bargain on the filter, it is recommended to DIY a drip filter box, I can't do it I can ask the guy in the aquarium store, so that there is basically no problem, the heating rod is prepared two, a 300w is used to control the water temperature, and a 100w spare, all of which are energized. If you don't feed the fish for three days, you won't explain it, and you won't know how to send a private message.

The key to raising good fish is filtration, and filtration is mainly to filter fish feces, and the toxins in the water are produced by fish feces. At present, the general aquarium filtration system is mainly upper filtration, drip flow, bottom filtration, filter barrel, side filtration, and back filtration, and these filtration systems are different in form, but they are essentially the same, all of which are filtration systems for cultivating nitrifying bacteria outside the tank. That is to say, the fish feces must be extracted into those filters before nitrification, and the ammonia in the fish feces can be removed.

These filtration systems need to pass through the water flow in the tank to pump part of the fish into the filter body, but there will always be some fish due to the multi-directional nature of the water flow in the tank, can not be pumped out and dissolved in the water, polluting the water body to increase the ammonia content, and it takes time to filter all these water bodies, fish live in the water body with ammonia poison for a long time, the physique will slowly become weak and easy to be attacked by the virus in the water, and the fish will be easy to get sick and anorexic. Therefore, it is often necessary to use a straw to suck out the fish in time and change the water frequently to reduce the burden of filtration, which increases the difficulty and workload of maintenance. Yongqing Filtration understands that this system has the function of automatically cleaning up fish feces, which will help.

The yellow stuff is the secretion of the fish, so if you want to look good, wipe it off, thank you.

Before they can be polycultured, the total number of fish to be kept needs to be determined according to the size of the tank.

In the same tank, it is more appropriate to polyculture these two fish in a ratio of 4:1.

When keeping both of these fish at the same time, the water temperature can be kept between 24-28, which is more conducive to stimulating their appetite.

They are all suitable for living in an environment with good water quality, and it is best to have a filter in the tank to maintain the water quality.

1. Can parrot fish and silver arowana be raised in one tankCan parrot fish and silver arowana be raised in one tank.

Because they are all tropical fish, the water temperature requirements are not much different, 24-28 is the temperature suitable for both to grow.

Secondly, the parrot fish is a middle layer fish, and the silver Arowana is an upper layer fish, and the two have different areas of survival and have enough living space. Filial piety.

Finally, there is less difference in the diet between the two when feeding.

If you are already an adult Arowana, you can feed the parrot fish first and wait until it is full, and then feed the Arowana.

In this way, there is no conflict between the two diets, the probability of a struggle is small, and they can coexist peacefully.

Second, what should be paid attention to in the polyculture of parrot fish and silver arowana, first of all, pay attention to the water temperature.

They are sensitive to changes in water temperature, so try to keep the water temperature between 24-28 and keep it constant to avoid being frightened by the change in water temperature.

Secondly, good water quality should be maintained.

When the water quality is good, they are less likely to develop diseases.

In addition, it is necessary to choose a suitable fish tank and give both of them plenty of space to move.

Also pay attention to the ratio of the two types of fish.

According to relevant information, when the ratio of two types of fish in the fish tank is about 4:1, it is easier for them to coexist peacefully.

Silver Arowana and parrot fish can be polycultured, but in the process of polyculture, it is necessary to ensure that their diet is balanced, otherwise there will be a phenomenon of biting each other. Generally, parrot fish will compete with silver Arowana for food, so it is recommended to feed the parrot fish first and then feed the silver Arowana to avoid them from fighting.

The personality of silver Arowana and parrot fish is similar, and they can be mixed together under normal circumstances, but it is recommended to keep them separately to prevent the phenomenon of mutual biting, which has an impact on silver Arowana and parrot fish.

If two kinds of fish are raised together, it is necessary to ensure that the feeding amount is balanced, otherwise the parrot fish may compete with the silver Arowana for food and bite the silver Arowana, and the silver Arowana may also bite the parrot fish.

Usually the silver Arowana and parrots are polycultured, you can feed the parrot fish first, and then feed the silver Arowana, which can prevent the parrot fish and the silver Arowana from competing for food and reduce the phenomenon of biting each other.

Parrot fish is more adaptable to water temperature and can live freely in the water temperature between 20-30, but in order to ensure better growth of parrot fish, the water temperature is kept at 28-29 degrees Celsius as much as possible, which coincides with the water temperature conditions suitable for the survival of silver Arowana.

The pH value of the water suitable for parrot fish is weakly acidic, so that parrot fish will be more active; For silver Arowana, the appropriate pH is .

Based on the above two points, parrot fish and silver Arowana have the same requirements for water quality, and the water temperature can be kept at 28-30 degrees Celsius when feeding, and the pH value can be adjusted.

Through domestication, the silver Arowana can also eat feed, and when feeding, the silver Arowana may eat the feed of the parrot fish, but it will not turn red. Put the silver dragon and the parrot together, they are eating each other's food, feeding each other together, and you can add some meat regularly to change the taste, and they are all living very well!

When feeding, you need to adhere to the principle of eating less and eating more often, and feed seven or eight minutes full at each meal, so as to maintain their vigorous vitality

Habits. Silver Arowana: It has a very mild personality among all arapaima and can swim with fish of the same size. It is also the most fertile of all arapaim.

Feeding habits are categorized as carnivorous, but it does not mean that they only eat fish. In addition to small fish, Silverribbon also eats many other things, and usually feeds on crustaceans and aquatic insects such as shrimp, daphnia, and midges when they are about 10 cm long, but it also catches small fish that swim 3 to 4 cm above the surface. In addition to swimming on the surface of the water, sub-adults also eat lizards, frogs, snakes, etc.

Adults over a metre tall also eat small animals such as chicks and rats on Mizushima, as hurricanes in the tropics often sweep many small animals on land into the water.

Parrot FishParrot fish can grind food and coral fragments with plate-like teeth in the pharynx. It can reach a length of 4 feet (4 feet) and weigh up to 20 kilograms (45 pounds). The body color is different, and there is a great difference between males and females in the same species, as well as between adults and juveniles.

Parrot fish are edible, but the entire taxa are of little economic value. The striped parrotfish (Callyodon fasciatus) is the dominant parrotfish in the Indo-Pacific region, measuring 46 cm (18 in) in length, with males green and orange or green and red, and females blue and yellow. Atlantic species include the queen parrotfish (Scarus vetula), about 50 cm long, with a blue colour of males with green, red and orange colours, and females pale red or purple with white stripes.

Parrot fish can generally be raised with silver Arowana, but parrot fish may compete for food of silver Arowana, if the silver Arowana is hungry, there will also be active attack on parrot fish, it is recommended to feed the parrot fish first, and then feed the silver Arowana to avoid biting.

Parrot fish and silver Arowana are common ornamental fish species, so can parrot fish and silver Arowana be polycultured, under normal circumstances, they can be raised together, but parrot fish may compete with silver Arowana for food, and may bite silver Arowana.

If the silver arowana feels uncomfortable with the environment or is hungry, the silver dragon will also take the initiative to attack the parrot fish, so it is necessary to pay attention to the feeding environment and avoid raising in a polluted and noisy environment.

If you want to raise parrot fish and silver arowana together, you first need to pay attention to the breeding environment, and then you need to feed the parrot fish first, and feed the parrot fish in an appropriate amount to avoid the phenomenon of parrot fish and silver dragon competing for food.
