How to raise resident crabs
The superfamily Hermitage Crab includes the Hermitaceae family, the Hermitage crab family, the Hermitaceae family, etc. Rare ones such as the Hermitage Crab family are The resident crab (square-armed resident crab) is very large, with the length of its large claws exceeding 10 centimeters. There are many spiny protrusions on the surface and edges of the two claws, and there are thorns on the legs. The superfamily Terrestrial Crabs includes Crabidae, Terrestrial Crabs, Chelicaceae Crabs, etc. Rare ones include Ehrlichia Crabs and Lower-toothed Crabs. Nearly 1,000 species are known in the world, and about 100 species in China. They are generally warm water species, with a small number of cold water species found in the Yellow Sea.
1. Information required for feeding
The basic requirement is to have a large enough tank, bottom sand, water basin and sea salt.
1. Cylinder: Needless to say, there is no need to say much about this. What needs to be noted is that most of the so-called "kitted cylinders" are very boring and the size is far from sufficient. Even if you want to raise two finger-sized crabs, you still need a 30cm square tank. If they are not raised alone, they must be separated during peeling.
2. Bottom sand: shell sand or coconut soil are suitable, general river sand or fine sand on the seaside are not suitable, ceramsite , stones are even more important. The thickness should be at least twice the height of the crab, and there are also requirements for humidity. It should not be too thick and there should be no accumulation of water. If it drips when you grab a handful, it is too wet.
3. Water basin and sea salt: This is also required. The water basin needs to allow crabs to enter and exit freely. It may be too deep or too deep.It doesn't matter if it has any weird shape, or even the bottom of a large mineral water bottle. Two are needed, one is fresh water, and the other is sea salt mixed with sea water (the ratio is not too strict, it can be lower)
2. How Feeding methods
1. Temperature: The temperature should not be lower than 70 degrees Fahrenheit and not higher than 78 degrees.
2. Humidity: Relative humidity is 70%, and relative humidity is about 50%. However, hygrometers generally measure relative humidity. Resident crabs like moisture, but moisture does not mean heat. You must pay attention to ventilation and remember not to close the breeding box tightly.
3. Cushion material: stones, sand and other items. The hermit crab is a nocturnal creature. During the day, it usually hides in sand and stone crevices. You must make the hermit crab feel safe, otherwise it is likely to commit suicide or commit suicide in an excited state! What kind of mat should be used? To be clean and environmentally friendly, it should be disinfected and left for a few days to allow the parasites and some toxic substances inside to evaporate and be killed.
4. Keep multiple resident crabs: It is recommended to buy more than 2 crabs. If the tank urinates, don’t keep too many. 2 or 3 crabs are enough. That's enough.
5. The environment of hermit crabs is hygienic: Hermit crabs are rotten creatures. If the surrounding environment is too dirty, they will get sick. Bacterial proliferation, parasite proliferation, etc.
6. The resident crab is a crustacean: its shell does not grow with the body and it needs to molt! It needs to be separated when molting. It stays in its shell every day, and it needs a quiet and safe environment. If several are kept together, move the ones that do not need to molt away to prevent the resident crabs from being attacked by other resident crabs while they are molting. The shell of a resident crab is basically changed once a year. Although its shell is changed every day, it is possible for shells of the same size to be exchanged. If there are several of them together, they may be exchanged for each other.
7. Sea water: Most of the food that resident crabs eat is water. Tap water cannot be used as the chemicals in it will kill them. A resident crab. Naturally, the best water for resident crabs to drink is sea water. If there is no sea water, remember not to add salt to the water, because the salt we eat contains iodine, and iodine is poisonous to resident crabs. The water also needs to be changed frequently, as does the food.
8. Bathing:Resident crabs need to bathe every week, and bathing is particularly necessary to keep their gills moist. Because the resident crab breathes through its gills, its gills must always be kept moist. The reason is to allow oxygen to melt into the water on the surface of the gills and then communicate with the capillaries on the gills. There must be no chlorine in the water. , the temperature should be room temperature, not significantly higher or lower than room temperature.
9. Shells: Resident crabs are gifted with the ability to change their shells. They put new shells of different sizes in the breeding tank for about three months to In about half a year, the beloved resident crab will switch to a new shell. As land resident crabs continue to grow, their shells become unsuitable, small or damaged, and they need to be replaced. When buying a new shell for the first time, it needs to be cleaned with warm water and calcium salt for about an hour. If it does not replace the new shell, it may mean that the current shell is still suitable.
10. If they suddenly escape from the shell, please prepare a few shells immediately and then immerse them in warm water. In addition, spray the naked land resident crab, or give it a sea bath for about 1 minute (warm water should be used, not cold water, and the water level should not be too high), and then put it and the previous snail shells into the shoe box. (If not, you can also find an ordinary box or box.) After closing the lid, there will be chaos inside. Follow along and protect the situation. After 1 to 2 hours, open the lid and take a look. If you are still naked, wait another 1 to 2 hours.
3. What do resident crabs eat?
Because resident crabs have a very mixed diet and are omnivorous animals, they are called scavengers of the sea. They eat everything from algae to food residues to parasites. For those who are keen on keeping fish at home, putting one or two resident crabs in the aquarium will act as a cleaner. The life span of resident crabs is generally 2 to 5 years. However, under good feeding conditions, they can often live to 20 to 30 years. The longest recorded life span is over 70 years.
