Aquarium crabs: species description and basis of contents

Crabs, of course, very interesting and colorful pets. However, deciding to settle such residents in your aquarium, you should first understand their preferences.

The most inherent quality of this arthropod is a quarrelsome character. And this applies not only to most species of fish or red-eared turtles.

Aquarium crabs also do not tolerate their relatives. You can be sure that by settling two males in one aquarium, you will inevitably become the culprit of constant battles for the territory or the attention of the female.

The result of such fights can even become severed limbs, which, however, then grow back.

The best option for a beginner will be settling into the territory of a small dwelling of the male and female. Subsequently, significantly expanding the habitat, you can hook up other residents.

The main thing is that they have enough space and do not have to defend their piece of land.

Strictly speaking, crabs do not really need an aquarium, but rather an aquaterrarium. You can achieve this by refitting the first one.

In essence, all species of crabs require about 30% of the land, the rest is water.

A powerful filtration system is also needed, since arthropods are very sensitive to environmental pollution. It is desirable to install an external filter.

Soil in the water is optional, but possible. Ground particles should be about 3-5 mm.

Greening a home is a procedure that is too complicated because of the crab’s love for greenery. Most likely, all plantings will be dug up and eaten. It is also worth adding that if there are several individuals, then they will definitely need shelters from each other.

It can be any decoration elements.

It is advisable to have a cover for the aquaterrarium, because these creatures run off surprisingly quickly, and then they have to look for them all over the apartment. True, there is one trick: you need to put a bowl of water on the floor – the fugitive will certainly sooner or later appear next to her.

Also at this point it is worth noting that crabs do not breed in captivity.

With regards to feeding these cute creatures, it is important to remember first of all that the share of animal food should be no more than 30% of the total diet. The most important and favorite dish – greens.

In the second place are vegetables, you can simply pour boiling water over them and give them. Next come fruit. Of animal proteins, preferably chicken fillet, liver, clams, mussels and squid.

These rules are the same for all kinds.

This species is the largest and most beautiful. For their maintenance, a spacious dwelling of approximately 50×40 cm each is required.

Water for such handsome men is needed with a pH of at least 7.2-7.5 and GH up to 10. The higher the salinity, the better.

For this purpose, you can use, for example, sea salt. Such an environment will help to neutralize the impact of harmful impurities on a sensitive marine inhabitant and properly maintain the balance inherent in the nature in which the crab has lived before.

Crabs are not accustomed to take food from the ground, it is better to spread it on another surface of the aquarium. Eating food looks funny: with both claws, the crab puts food into the mouth.

The diet is varied, both vegetable and live feeding, seafood.

You can feed vegetables (except potatoes). Eat fruit, chicken fillet, mussels, shrimp, squid.

They like greens: lettuce leaves, dandelion leaves, nettles, pretreated with boiling water. It is advisable to add calcium-enriched feed for normal shell growth.

Having accumulated enough nutrients in it, the freshwater crab sheds and discards the old shell.

Types of aquarium crabs

Dutch crab Some freshwater crabs live only in fresh water. These include representatives of the squad Decapoda. The unit belongs to the family Potamonidae, which includes in its ranks about two hundred species.

Among them are also tropical.

But in the rivers, lakes and in the waters of the Black Sea lives another freshwater representative – Potamon Potamonis or the Dutch crab. In these reservoirs, the aquarium crab also feels excellent due to the fact that the life-giving moisture is slightly alkaline and hard.

At the bottom of the reservoir there are also limescale. You can meet this type of aquarium crab both in the pond and on the shore.

It is worth noting that quite rarely aquarium crabs feel great in seawater and freshwater.

Let these types of aquarium crabs still occur, but this is more of an exception than a rule. Grapsidae In total, there are two species of aquarium crab in nature that can live normally in sea water and freshwater rivers. We are talking about freshwater crabs such as Eriohair and Helice.

These representatives of the water world came to us from the Far East, they belong to the family of sea crabs – Grapsidae. Often in nature, they move from the salty sea depths to rivers that flow into the sea.

These animals are also found in domestic waters. The conditions of keeping aquarium crabs of these species are important. Only in pure and oxygen-rich water can these types of aquarium crabs be contained.

Otherwise, in worse conditions, they may die.

Favorable content in clean water and enriched with nutrients feeding does not guarantee the appearance of offspring. This is due to the fact that crabs – territorial animals, are prone to conflict.

Even the owner can pinch the finger.

In the natural environment, arthropods breed for three summer months, when the weather becomes warm and comfortable. Breeding females simultaneously monitor the older brood, bearing new spawn.

Fry in the first months of life often molt. Breed in the prepared shelters.

Due to their nature, they are very sensitive and aggressive during this period.

What crabs eat: make up a pet menu

Crabs are not only a tasty dish in a restaurant. Today, a new and rapidly growing trend has become the equipment of aquariums with sea water. Therefore, crabs have become favorite pets.

Interesting and clever enough, with a peculiar behavior, they attract the attention of fans of the underwater world. By the way, crabs exist a great many, there are freshwater individuals, which can be hooked into the most ordinary aquarium.

However, today we will talk about what crabs eat.

From technical equipment you will need a filter and aerator, as well as a set of lamps. It is advisable to immediately choose a large aquarium, so that each individual has at least 0.3 square meters, because these amazing creatures love to travel. In the water you can inhabit small fish, like guppies.

But larger fish crabs caught and eaten. In captivity, crabs grow to 10 cm and live for 5-7 years.

To multiply them is difficult, they need special conditions and sea water. They have a planktonic larval stage, so it can hardly be expected that you will admire small crabs.

However, mating behavior in the aquarium is observed quite often. This is not surprising, since almost all species behave when the conditions of detention are close to ideal.

On the one hand, it is still exotic, and there are practically no experts in the field of crabs. On the other hand, they keep the same house frogs and newts, turtles and other creatures that once seemed completely inappropriate for an aquarium.

And they also peacefully coexist with fish.

Speaking about what crabs eat, it is worth remembering that in nature these creatures are completely omnivorous. They are happy to have breakfast with insects, cubs of other crabs, berries or algae.

Almost everything that they come across on the way, they will definitely check for edibility.

Let’s now pay attention to our countryman. He lives in large numbers on the Black Sea coast.

A lot of tourists decide to grab one with the other. If you can bring your pets home alive, you can settle them in your aquarium. What do Black Sea crabs eat?

In principle, everything is the same as crayfish. Will be happy to eat moths, any live food, chopped meat, that is, everything that falls to the bottom of the aquarium.

However, it is very difficult to maintain a sea crab at home, because it needs special conditions. Therefore, it is better to buy in the pet store freshwater, adapted crab.

You will also be offered specialized food for these arthropods.

The most important rule here is not to overfeed. In principle, we have already listed what sea crabs eat at home.

Any fruits and vegetables, berries, meat and specialized food. The most important thing is not to overfeed the pet.

Daily feeding is the greatest evil for arthropods. You need to give food three times in ten days.

That is, once every three days.

In this case, protein products can be included in the diet of the crab no more than once a week. The quantity for one individual is about a large pea.

You can change food from time to time, it can be a shrimp or a piece of raw meat, a little fish. On major holidays (in the literal sense, stick to the calendar, so as not to be confused) you can give mussels and oysters.

Be sure to give your pet mineral supplements. It can be shredded eggshells or chalk for parrots. It should always lie on land.

In the water is to add a little sea salt, which is bought at the pet store. Add will have to the eye, so it is better to less than more. This is important in order to preserve the integrity of the shell.

Do not use sea salt for bath, it has a lot of dyes and flavors.

Aquarium crabs get along poorly at home with their own kind. If you are not a fan of fights and murders, then it is better to put one pet in the aquaterrarium. Despite the peace-loving attitude towards humans, crabs are quite aggressive towards males.

In the wild, serious clashes constantly arise between them for any reason, which often end in the death of the weakest. However, it is necessary to distinguish the content of the house from the wild.

Here individuals have no opportunity to hide from each other and in the end only one will survive.

You can wind up two or more crabs if you have the opportunity to provide everyone with their own territory. Best of all, if the crab will have no less than 50 square centimeters.

He will guard his territory fiercely.

Does not accept the cancer of the neighborhood with fish, snails and frogs. Of course, for a few days you will still be able to watch the full aquaterrarium, but after that the number of the latter will significantly decrease until it disappears completely.

Once a season, crabs molt. The frequency may vary depending on the conditions of detention. In the first place – the temperature.

Molting occurs in salt water (exception Potamon potamios). The optimum salinity of water ranges from 15 to 45%.

Shedding is necessary for crab growth. Within a few hours, it is in the water and in turn removes all limbs, tail and body from the old chitinous refuge. After that, the crab sits in a shelter for several days and does not eat.

It leaves from there only after the shell becomes stronger. At such moments, he is defenseless and can be easy prey, so the ideal option is to arrange a temporary shelter from the brethren.

Life expectancy at home from 3 to 5 years.

How to keep a crab at home :: how to care for crabs :: Other pets

Among all the aquarium crustaceans inhabitants of the crab is the most vivid and interesting. Breeders of these creatures are attracted not only by their unusual appearance, but also by a rather entertaining behavior.

A crab can become a decoration of a home aquarium and a true pride of its owner, if you create optimal conditions for it, close to those in which these creatures live in nature.

Question “Snowy turtles.” – 3 answers

  • – aquaterrarium;
  • – lamp;
  • – coarse sand;
  • – stones;
  • – granulated feed for aquarium fish;
  • – vegetables, fruits, fish, seafood;
  • – cooking or sea salt;
  • – calcium chloride;
  • – ceramic shards.

1. Before you buy a crab in a pet store, you need to choose the most suitable home for it. A normal aquarium, i.e. room water without land, will not work.

For keeping crabs at home, you need a special aquaterrarium, in which a sufficient amount of water will be combined with stone islands and diverse vegetation. The size of the aquaterrarium, as well as the ratio of water and land, depends exclusively on the type of crabs you choose.

2. The fact is that the crab spends most of its life on the shore, and not in the water. In order to create optimal living conditions for the pet, arrange its home so that the crab can easily move from a small artificial reservoir to the shore.

Place a lamp over the stone islands. Crabs love the light, you can often watch how your pets willingly visit the artificially created “solarium.”

3. As a substrate, use coarse sand. Constantly moisten it with a dropper or tidal system. The thickness of the sand layer should be about 5 cm.

The same value should be followed when organizing a crab pond. Water in it should be hard and lightly salted.

In order to cook it, dissolve 1 tsp. sea ​​or salt and 1 tsp. calcium chloride in 10 liters of water.

4. It is advisable to install a filter in the crab pond. These creatures feel good in clean cold water. Change 25% of its total amount will have weekly.

It is necessary to wash the soil and clean it from feces and food residues every two months.

5. Take care and the construction of shelters for crabs. These creatures stubbornly defend their right to privacy, so they just need a secluded place in which they can hide from prying eyes.

Ceramic shards of various sizes and gaps between large stones can play the role of shelters.

6. In terms of food, domestic crabs are unpretentious. The basis of the diet can make a high-quality granulated feed for aquarium fish. Crabs will not refuse from Gammarus, bloodworms, pipemaker and dry daphnia.

Diversify your pets with finely chopped vegetables, fruits, fish and seafood. Carefully place the small pieces of these delicacies in front of the crabs resting on the stone islands.

7. If you do not want to periodically observe the “gladiator fights” and fierce battles, get one crab. These creatures are inveterate individualists, so they feel much more comfortable in solitude than in a society of their own kind.

Despite the attractive and innocuous, at first glance, appearance, crabs are quite aggressive. In nature, battles for territory, shelters, females and food often occur between males.

Often, these fights are fatal.

First you need to choose a suitable aquarium or aquaterrarium, as a freshwater crab needs more land than water. The land area should be about 30/35 cm.

The content in the aquarium implies a small level of clean water, from which protruding stones should appear on the surface, on which the crab will dry or bask under the lamp.

Crabs need shelter in the form of caves, grottoes, logs and pots. So their conflict with other inhabitants will decrease.

Crabs, like other crustaceans, often escape from the tank through cords or other ways, so the aquarium should be closed with a net or glass, while ensuring normal air circulation.

Good water filtration, moderate lighting, maintaining the correct temperature of 22-25 ° C and salinity of water are needed. Acidity should be not less than 7.5, and the hardness not less than 10 °.

Mineral-rich water will greatly facilitate the life of crabs in captivity. The sand should be regularly washed, as there is accumulation of crabs excrement.

Weekly you need to replace a quarter of the volume of water and siphon the soil.

The crab feels keenly that the water contains metal impurities, especially copper. Oxygen compressor plays a big role in the life of crabs.

One of the common causes of the death of crabs is overcooling or overheating. In a comfortable environment, these aquarium crustaceans live 3-4 years.
