What crabs eat: make a menu for a pet

Crabs are not only a delicious dish in a restaurant. Today, a new and rapidly gaining momentum has become the equipment of aquariums with sea water. Consequently, crabs have become favorite pets. Interesting and intelligent enough, with a peculiar behavior, they attract the attention of lovers of the underwater world. By the way, there are a lot of crabs, there are also freshwater species, which can be populated in a very ordinary aquarium. However, today we will talk about eating crabs.

Aquarium equipment and reproduction of crabs

Of the technical equipment you will need a filter and aerator, as well as a set of lamps. It is desirable to immediately choose a large aquarium, so that each individual accounted for at least 0.3 square meters, because these amazing creatures are very fond of traveling. In the water you can populate small fish, like guppies. But larger fish crabs will be caught and eaten. In captivity crabs grow to 10 cm and live 5-7 years.

It is difficult to replicate them, they need special conditions and sea water. They have a planktonic larval stage, so you can hardly expect that you will admire small crabs. However, marital behavior in the aquarium is observed quite often. This is not surprising, almost all kinds behave this way, when the conditions of detention are close to ideal.

On land and at sea

This is an important point, so we will dwell on it a little. What crabs eat must necessarily be on land, since these amusing creatures feed mostly on the shore, although they are looking for food and under water. Therefore, they need a special aquarium, which has an underwater zone and a beach, at least a third of the total area. Approximately the same terrarium is needed for newts and turtles. The water layer can be shallow, not more than 15 cm. The coastal zone should be clearly marked with a high, large stone, in this case part of the soil will seep between the slots and create a beautiful descent into the water.

It must be remembered that on the shore crabs not only feed, but also dig themselves holes. If you do not take it into account, your whole composition will be spoiled. Therefore, on the shore, a clay pipe with a diameter larger than the crab itself is dug in. So that the water does not stagnate, it must be through. Crab will constantly engage in deepening this hole, dragging the soil into the water, and then you can again organize a collapse.

On the one hand, it is still exotic, and there are practically no experts in the field of crab science. On the other hand, they keep the houses of frogs and newts, turtles and other creatures that once seemed completely unsuitable for the aquarium. And they also peacefully get along with the fish.

Speaking about eating crabs, it is worth remembering that in nature these creatures are absolutely omnivorous. They will enjoy breakfast with insects, cubs of other crabs, berries or seaweed. Virtually everything that comes across them on the way, they will certainly check for edibility.

Nutrition of unusual pets

What crabs eat, you can enumerate endlessly, because they do not refuse almost any food. It is best to immediately establish a system of evening feeding, as crabs feed at night. Although if you consider that they are big lovers of falling, then nothing will happen if food stays in the aquarium in the morning. The maintenance on land and "at sea" avoids the problem that is most relevant for beginner aquarists. This is the decay of food in the water, why it quickly deteriorates and is inhabited by harmful microorganisms. In the case of these funny animals, you can leave delicacies on the sandy shore. In the evening a very interesting picture unfolds here, a crab meal is a whole show that you need to see.

Basic diet of rainbow crab

What you eat at home, you can easily find in your refrigerator. The main diet is a salad, so for winter time, plant several beams at home. These animals are not too gluttonous, so you will have enough of this amount until the very spring. This plant is most useful, since it is the closest in composition to the one that the crab feeds on the African homeland. If there is no salad, then you can get a Bulgarian pepper or carrots, an apple. And any of these products can lie on the sand, until it dries.

In principle, in order to organize the optimal diet, it is enough to ask what the crabs eat in the sea. The main diet of iridescent handsome people is a special alga, which was mentioned above. However, they feed on carrion, fish and shellfish, so they will not refuse protein food in the aquarium. A normal fish food (live or dried) is perfect for feeding arthropods.

Black Sea crab-flounder

Let's now pay attention to our fellow countryman. It lives in large numbers on the Black Sea coast. Many vacationers decide to take one or two with them. If you manage to take your pets home alive, then you can settle them in your aquarium. What do crabs of the Black Sea eat? In principle, everything is the same as cancer. They will be happy to weave bloodworms, any live food, sliced meat, that is all that will fall to the bottom of the aquarium.

However, keeping the sea crab at home is very difficult, because he needs special conditions. Therefore, it is better to buy a freshwater, adapted crab in the pet store. Also, you will be offered a specialized feed for these arthropods.

How often can you feed a crab?

The most important rule here is not to overfeed. In principle, we have already listed that eating sea crabs at home. Any fruits and vegetables, berries, meat and specialized food. The most important thing is not to overfeed your pet. Daily feeding is the greatest evil for an arthropod. You need to give food three times in ten days. That is once in three days.

In this case, protein products can be included in the crab diet not 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, some fish. On major holidays (in the literal sense, adhere to the calendar, so as not to be confused), you can give mussels and oysters.

Be sure to give your pet mineral fertilizing. It can be crushed egg shell or chalk for parrots. She should always lie on land. In the water it is worth adding a little sea salt, which is bought at the pet store. To add it is necessary on eyes, so it is better less, than it is more. This is important in order to maintain the integrity of the shell. Do not use sea salt for bathtubs, there are many dyes and flavors in it.

Will not the crab stay hungry?

As for this, anxiety is unnecessary, your pet will definitely not starve. In nature, they can do without food for several months, and a week without food will not bring any discomfort. Overfeeding is the cause of various health problems for your pet. The crab begins a frequent and problematic molt, which is a great stress for his body.

Moulting is a normal physiological process, but the crab suffers from lack of movement in the aquarium. In nature, it can go up to 3 km per day. As a result, being in conditions of constant growth and lack of movement, he does not manage to complete the cycle of recovery and preparation for a new molt. And this will lead to the loss of limbs and death.

Treats

We have already said that the crab meal is the most fascinating sight. The hosts of these amazing creatures will gladly tell you how the crab eats the cherry. Yes, they are very fond of sweet berries. Like a small gourmet, the crab gradually tears off a piece by piece, fingering. At the same time he eats very culturally, putting small pieces into his mouth. It is a pleasure to watch the crab eat cherries, cherries or apricots. Vitamins are useful to everyone, so from time to time, always give a small berries to a small animal.
