maintenance, care, compatibility
At once we will say that this neighborhood often brings only problems. There are, of course, cases when crayfish coexist well with fish.
But even more situations where one or the other side suffers as a result of such a tandem. For example:
- Soma are arthropods’ competitors for food and shelter. Collisions on this ground are inevitable.
- Small fish like neons, guppies, etc. can be crayfish elementary eaten.
- Large fish with long tails and fins (gold, angelfish, etc.) can lose their wealth.
- In the vicinity of large, but aggressive fish like cichlids, crayfish are doomed to hunger and stress, and ultimately to death.
Thus, if you are not ready to take risks and experiment, keep the crayfish apart.
From the place of purchase to the place of residence of arthropods transported in a black opaque package. Adaptation is fast.
It should be borne in mind that the temperature difference in the package and in an artificial reservoir should not be more than three degrees. The following conditions are considered optimal for cancers:
Aquarium. The minimum volume of the tank must be at least 15 liters per 6 cm specimen.
However, given that close housing provokes crayfish to aggression, it is better to take a vessel as spacious as possible. From above, it is imperative to install a cover with small holes, as in case of overpopulation, the crayfish will be trying to get out of the aquarium when overcrowded, the water is dirty or oxygen-poor.
If possible, the best option is to equip the aquaterrarium.
Water must be clean, rich in oxygen, with a temperature in the range of 17-21 degrees and a hardness of 8-12. To increase the stiffness in the ground, you can put marble or limestone. It is better to install an internal filter in order to stop attempts to escape by wires.
Cancers love to hide the remnants of food, which then rot and spoil the water. In this connection, regular replacement of 50% of water is necessary.
Priming better to choose large. Crayfish dig holes, and not a single plant will take root in the shallow soil.
Vegetation. Algae is better to pick up with strong roots, large leaves and strong stems.
Before planting, they should be held in quarantine.
Registration. Various stones, snags, hoses, halves of ceramic flower pots, grottoes, etc. can be used as decorations. From them crayfish build shelters for themselves and climb them to the surface of the water.
It is better to do this in the evening hours, as the daytime crayfish hide. If arthropods coexist with fish, in the latter by the evening the activity decreases, and they will not drag feed from claw carriers from under the nose.
Despite the fact that aquarium arthropods are omnivorous, there are some nutritional recommendations for them. Over eighty percent of the daily ration of crayfish should be plant food. You can give elodey, nettle, water lily, rdest, algae, carrots, zucchini, spinach, parsley.
For a variety of give various mollusks, insects, worms, tadpoles, frozen bloodworms, feed for bottom fish.
As a delicacy, you can sometimes treat fish to pieces or lean meat. Meat can be raw, boiled or in the form of stuffing own twist without store additives. Interestingly, crayfish prefer it in a slightly rotten condition.
Protein food is given no more than once a week, since it has been observed that it increases aggressiveness.
Special feeds for crayfish and shrimp are also available, which can also be used (for example, such brands as Dennerle, Tetra, MOSURA, Genchem Biomax series). They strengthen the immune system, maintain the brightness of pet coloring.
There are granules, plates, sticks.
As for the frequency of meals, there is no unity of views. In some sources, it is recommended to feed females once every three days, males – once every two days.
Others advise for both sexes meals once a day. Therefore, here you can see for yourself the behavior of your pets and by trial and error will select your ideal schedule. During molting or crayfish breeding, the number of meals increases.
Young individuals readily take ready food for fry, artemia, shredded tubule. In addition, they still eat organic decay products, thus cleaning the aquarium.
To improve digestion and prevention of parasites, dried leaves of oak, alder and beech are given.
The mating period in adults begins after the completion of molting. In females at this time there is a selection of pheromones, which attract the opposite sex, and the males go in search. It is very interesting to observe how the formed couple dances, sometimes for several hours, touching each other with their antennae.
After that, the female is recommended to be planted in a separate container, where after 20 days she will lay eggs.
Relocation is necessary, as heightened anxiety and anxiety make her protect her offspring and show aggression towards everything around her. The eggs are attached by a sticky mass under the belly, and the female moves with them. Offspring fearfully and for a long time prefer to hold on to the torso of the mother.
Eating crustaceans themselves begin only after the first molt. Shelters for young stock is a prerequisite to survive, hiding from offenders (including adult crayfish).
After the second molt, the offspring gains sufficient autonomy, and the female is again resettled.
There are many, but here we consider only the most common.
This disease is very common in aquarium arthropods. The reason is the poor conditions in the aquarium.
The simplest microorganisms settle on chitinous integuments, as a result of which the cancer looks covered with brown or grayish-white foam. If this plaque spreads to the gills, then the animal will not be able to breathe and will die. For recovery, it is necessary to put in order the water and the number of inhabitants in the aquarium.
At the time of illness, the animal is quarantined.
Large crayfish, able to live in home aquariums, are rarely found among amateurs of aquarium dwellers. Recently, however, more and more people prefer unusual options.
Many males and females have a calm character, require a minimum of time and attention, are ready to please with bright colors and interesting behavior.
In the world of crayfish can live in various waters. Due to this, they are successfully found in various states and are among the most common inhabitants of reservoirs.
If desired, you can breed cancer in the aquarium at home, but you need to understand the features of caring for him.
One cancer is allowed to keep in the aquarium of small size. If you expect a regular replacement of water, you can stop at 30 – 40 liters. In any case, it is necessary to provide shelters, as most often crayfish hide the remnants of food in caves or pots.
It is important to prepare for a large amount of leftover food, regardless of the fact that there is an aquarium inhabitant. If you do not take into account this factor, you can face a serious imbalance of water and the need for its frequent replacement.
It is advisable to conduct regular checks of secluded corners of the aquarium in order to maintain cleanliness in the house of the male and his females.
If large crayfish live in an aquarium, a volume of eighty liters is required. It must be remembered that the inhabitants are cannibals, because they can eat each other.
Moreover, the risk increases with moulting, when any gender becomes dangerous for neighbors. Wanting to protect the crayfish from each other, you need to take care of the presence of a spacious aquarium with numerous shelters.
The male and female must be able to hide from each other during shedding.
To filter the aquarium, it is desirable to use an internal filter. The most important thing is to understand how to maintain decent comfortable living conditions for aquatic inhabitants.
If an external filter is used, the situation with the hoses may not be as desired. Cancer is able to get out of the hose and start crawling around the apartment. It must be remembered: the crayfish are capable of escaping.
Wanting to protect the apartment from the male and his girlfriends, it is desirable to tightly cover the aquarium. Moreover, it will not be very pleasant to understand early in the morning that the male escaped with his girlfriends, who almost died, because cancer cannot live without water for a long time.
Reproduction of crayfish in aquarium conditions can occur. Wanting to facilitate such a task, you need to understand that the conditions of the aquarium are radically different from the natural factors in the natural world.
In this regard, it is desirable to determine the moment when the most important stage for the emergence of offspring begins. During this period, it is desirable to pay increased attention to water parameters and include high-quality feed mixtures in the diet of the inhabitants of the aquarium.
What is the scheme for breeding crayfish?
- Mating is the basis for further reproduction. For this, nature designed special antennas.
- After 20 days, the female sex lays eggs that are attached under the abdomen. To lay the female must sink to the bottom. Any movement is disturbing, because in such a crucial period it is desirable to prepare another place of residence for the female.
- After a time, crustaceans hatch, which after a couple of months can begin to eat on their own.
In order for the male sex of the crayfish to not frighten the Maltsy, it is best to take care of increasing the number of shelters. Otherwise, one cancer eats another, which is not desirable for the fauna.
- Crayfish is the most common in the world. Unfortunately, it will not be possible to keep it in the aquarium for a long time. Wanting to distinguish crayfish from others, it is necessary to note the large size and agility. Crayfish can eat small fish and swallow plants. For long life requires cold water, as a result of which health deteriorates quickly and life expectancy is reduced. Crayfish in an aquarium can live if you prepare for it a separate house.
- California red cancer is truly popular in the world among aquarists. You can distinguish it by its unique appearance: a bright red color and a length of 12 to 15 centimeters. Life expectancy is 2 – 3 years. California cancer is unpretentious.
- Marble cancer is one of the most special in the world. All individuals are females. Wanting to distinguish the gender of marble cancer, the task will be a failure. In addition, females breed successfully without partners.
- Blue Florida cancer turned out to be popular all over the world, but its coloring was artificially obtained.
- Louisiana dwarf cancer can be distinguished due to its small size (length is 3 – 4 centimeters). Life expectancy is about 15 – 18 months. The small size leads to the fact that the Louisiana cancer must be peaceful, and it can successfully coexist even with fish.
Wishing to distinguish one’s love for crayfish before other aquarists, one should study all the existing varieties and give preference to the most beautiful of them, properly care for aquarium kids and contribute to the preservation of good health, long life.
The tendency to breed crayfish in aquariums appeared relatively recently. Some time ago, aquarists did not take the crayfish seriously, paying more attention to the fish, and the crayfish were rather exotic.
However, today the picture is changing, and more and more often in the aquarium of a keen enthusiast you can also see crayfish. Especially because they are very interesting to watch.
They are distinguished by a calm disposition, interesting behavior, and care is not distinguished by high complexity. On the whole, breeding aquarium crayfish is a fascinating and interesting process.
Recently, quite often owners of aquariums are settled in a crayfish tank. Watching them is very interesting, especially when they wash. But the opinion that they do not require special care is wrong.
Of course, no one cares for crayfish in the pond, but it is there that all the conditions for a comfortable stay are created. It is the same conditions you need to create at home.
The aquarium should be spacious. River crayfish take a lot of space to move around and get food. At the bottom should put a small, clean pebbles.
In addition, it is necessary to build a refuge of large stones. This is necessary so that cancer hides in the daytime.
Without shelter, he may be stressed out due to fear.
The maintenance of crayfish in an aquarium implies not only care, but also the creation of conditions close to natural ones.
Water should be 25 degrees. Crayfish calmly tolerate climate change, so they are not afraid of night temperature changes. However, strong warming can adversely affect the health of the animal.
Water should not be acidic. In such a liquid, the crayfish will die.
As for nutrition, it should be varied. In the aquarium, it is necessary to plant river plants, which the cancer will eat a little. It is important that there are superficial plants.
Eating crayfish can and conventional food for fish. Only need to buy food that will sink to the bottom. Sometimes you need to give delicacies – raw meat, fish and earthworms.
All this animal with pleasure will eat.
How to keep crayfish in an aquarium if there are other aquatic inhabitants? All listed conditions must be met.
But beyond that, don’t forget about the fish.
It is better to transplant small individuals in order to avoid not to find them in the morning. It is also important to ensure that the crayfish get food.
They easily die of hunger, so you can not leave them without food.
Crayfish are subject to molting. For the year, they can change color two to three times.
This is a completely normal phenomenon, which is observed in nature.
Frequent molting is dangerous. If this happens, then you need to look for the cause in the water. Usually, crayfish begin to fade when the climate changes.
This means that the conditions for a uniform water temperature are not created in the aquarium.
Or, when the aquarium is near windows or heating devices.
When the house has a large aquarium, there is a desire to populate it with all sorts of exotic inhabitants, so that it is beautiful and unusual. Many buy crayfish and settle them with fish.
But is it possible to do that? Do two different kinds of inhabitants live together in the same container?
Almost all the crabs are peace-loving creatures. They do not create conflicts, sit quietly in the shelter during the day, and go out in the evening for food. They slowly move along the bottom of the aquarium, collecting prey.
But sometimes the crayfish in the aquarium and fish – it is not compatible. There are many reasons for this.
Most importantly, small fish can easily eat cancer. Despite the fact that the fish move much faster, at night they sleep at the bottom of the aquarium.
At this time, the hunt goes cancer and eats everything that is bad. He may not eat other inhabitants, but fairly cripple them, leaving without a beautiful tail.
This applies to big fish. And sometimes it even causes serious wounds, after which the fish die.
The second reason for incompatibility is a possible famine. Pisces do not know the feeling of saturation and are able to eat everything that they will be given.
Due to this slow, nocturnal crayfish may simply not get food. Having lived in hunger for several days, they will die.
This problem is quite easy to solve. You need to buy food that settles immediately to the bottom and pour it into the aquarium in the evening when the cancer comes out to eat.
Do crayfish live in an aquarium with other inhabitants? They live, but it is important to find him normal neighbors.
Fish should be calm, not predatory, not very small. In this case, a favorable neighborhood is possible.
But, nevertheless, it is better to equip a separate terrarium for crayfish, where all conditions will be created for it. For example, they need a snag to get to the land.
And the walls of aquariums must be high so that the crayfish cannot get out. Again, food.
You can feed them with pieces of meat or fish. The remains of food quickly deteriorate and pollute the water.
And often you can not replace the fish in the new liquid.
Wanting to get a crayfish, it is better not to risk the existing fish and not experiment with the health of a new tenant. Cohabitation can bring a lot of trouble to the owner and the cost of new fish.
Therefore, it is better to equip another aquarium and then quietly enjoy the vital activity of healthy fish and crayfish.
Briefly about the content of invertebrates and other animals in the aquarium
The content of crayfish in an aquarium creates many problems (and here we talked about the most popular crayfish in the aquarium). They will hunt any fish that dare to swim close. And believe me, with their external sluggishness, they can be very fast!
Often, inexperienced aquarists plant crayfish in a common aquarium and then wonder where the fish go … In addition, they actively dig up the aquarium to suit their design needs and at the same time cut the plants. Suffer from their attacks and even fellow shrimp.
The best thing is to keep the crayfish in a separate aquarium, because they can really be very beautiful. But also dangerous for other residents.
If you want to have cancer, then the Mexican orange dwarf cancer will be the most accommodating and beautiful.
