Content

Cancer aquarium marble does not need a large area for maintenance. For one individual, 5 liters of water is required. The temperature in the aquarium should be medium - about 25 degrees. It must be supported by a special heater. Although this representative of freshwater can withstand a temperature jump from 28 to 18 degrees and vice versa. There must necessarily be a filter and aeration - cancer needs a lot of oxygen, without which they can die. At the bottom of the aquarium you need to lay sand or small pebbles. It also requires artificial shelters, imitating the environment in the natural environment - stones, driftwood and so on. Plants should not be planted, since the aquarium cancer enjoys with pleasure green algae and can even bite the plastic grass, which is fatal for freshwater. Water should be changed at least once every two weeks as pollution occurs. The aquarium for crayfish should always be clean, so as not to harm the inhabitants. With freshwater fish live poorly - at night they go hunting and can destroy their neighbors or spoil their fins. Podkazhivat to crayfish can be large fish, living on the surface of the water.

Feeding

Aquarium inhabitants eat almost everything. Cancers can be fed with mixtures for catfish, so that the pellets quickly settle to the bottom. Sometimes it is necessary to give the pet food to pieces of veal or liver. Only give food in small portions so that it does not fade and does not spoil the water. It will be useful to feed young beans, spinach, carrots or peas. Pre-vegetables should be doused with boiling water. For the winter, you can freeze the greens. If the breeder wants his pets to live and multiply for a long time, then you need to diversify the menu, and not give exclusively purchased feed.

Breeding

Marble cancer aquarium has one distinctive feature - it has no sex. Rather, it combines both male and female individuals. The first sign of the soon to be replenished is the permanent shelter of crayfish. There they are fertilized. First time they are caviar worn on the abdomen, about 4 weeks. After this, there are small crustaceans, which immediately begin to jump in the ground and eat the remains of food. An adult is recommended to be planted in another aquarium in order to save offspring. Also, many representatives of catfish can regale their babies, so it's worth keeping them separate. They feed on everything, like adults. But for rapid growth, it is more often necessary to include fresh meat in the diet. Unfortunately, not all babies survive. Weak crustaceans die or become prey to stronger relatives. But with proper care and feeding, there are about 80% of the offspring born.
