Freshwater crab: photos, conditions of breeding

Hello dear colleagues aquarists. Today I would like to write about the next inhabitant of the aquaterrarium, namely about the freshwater crab. In nature, it lives in small mountain streams and streams with a rocky bottom.

This animal is widespread in freshwater in the Himalayas.

In freshwater crab, unlike other members of this large family, there is no bright exotic color, but with all this, a pleasant appearance is not deprived. The back of a freshwater crab is blue, and when the sun comes onto it, it becomes bluish. Pincers, belly and head can be colored dark brown or terracotta.

The sizes of these crabs are small, the females are slightly smaller than the males. It is possible to distinguish a male from a female by using larger claws and a pointed abdomen. In females it is oblong and wider.

And the color of the males has a more saturated color. In artificial conditions, a freshwater crab can live up to 4 years, but this is on condition that it will be kept in optimal conditions.

All freshwater crabs are land animals, as they spend almost all the time outside the reservoir. Very often they climb stones protruding from the water and rest there under the sun. This type of crab is quite active.

The animal hides in deep holes, which they dig themselves near the coast in the wet sand. At night, the animals leave as far as possible from the water and hide in the crevices of rocks or small caves.

Consider these moments, when you equip for the maintenance of crabs.

The freshwater crab is rather aggressive and nervous in nature. In one tank between two individuals, fights often occur against the background of redistribution of the territory of influence.

But in nature, they lead a more secluded lifestyle. Based on this, if they do not have enough personal territory, they will constantly sort things out with their relatives. The best option is if one male and several females live in the same aquaterrarium.

But at the same time may occur clashes. Do not keep two males in one tank.

To minimize hassles, place more different shelters in the form of stone caves and coconut shells in the tank where your pets will hide.

The water level in the aquaterrarium should not be more than 12 centimeters. Try to make a few islands of stones and snags so that they look out of the water.

On them, your pets will crawl out to rest. Coarse sand, gravel and pebbles can be used as a substrate. Freshwater crab health is greatly affected by water quality.

It should be clean and well enriched with oxygen. Do not forget to install a filter and aerator.

Also be sure to spend weekly changes.

During molting, until the crab’s shell hardens, the animal is very vulnerable and not protected by anything, and therefore, they never leave their shelters. For this reason, crabs do not even eat for several days, but only sit in hiding places.

When the chitinous shell becomes strong and firm, crabs leave their shelters and go in search of food. The main thing here is to help the crab with this business at first, spread out the food near the shelter, because if the crab remains hungry, it will start to eat everything that comes to hand, including even small fish, if there are any.

Food is best laid out on land, because this type of crabs does not feed in water. When you create land islands, make a small flat platform on which pets could eat.

Freshwater crab is not picky about food, so there may be small insects, bloodworms, snails, small pieces of fish and meat in its diet. In addition, experienced aquarists advise to make special mixes yourself.

They should include: meat of shrimp and squid, lean river fish and beef heart. Grind all this in a meat grinder and put the mixture in the freezer.

And when you need to feed pets, a certain amount of feed defrosted.

Feed crabs need every two to three days, otherwise a large number of residues of rotting food will accumulate in your aquaterrarium, which will pollute the reservoir. In order for your pet to grow and develop well, include in its diet daphnia and gammarus, which should be given a couple of times a month. Just freshwater crab is not against eat vegetable food.

Therefore, they can be fed every day with lettuce or nettle leaves, apples and bananas. Only beforehand do you need to scald it with boiling water.

Under aquaterrarium conditions, the freshwater crab does not reproduce, as in nature their offspring pass through the plankton stage. Naturally, you will not be able to create suitable conditions at home.
