The first thing you need to keep a pet crab is a container of the right size, usually a basin, but the wall of the basin should be high and steep, or smooth, in order to prevent it from climbing out.It can also be raised in a fish tank, but it is better not to be too big, so it is not convenient to manage.Put some sand in the container, and also need to hide in the house.
Crabs need to put a certain amount of water, because the animal itself lives in the water.However, its demand for oxygen is relatively high, so generally do not put too much water, it is best not to pass its body, so that it can breathe better.Water should be changed regularly to keep the water clean and hygienic.
If you raise crabs at a deep water level, you need to keep it oxygenated.One end of the oxygenation pump is connected to the water, so that the oxygen content in the water body can be maintained all the time, which is very helpful for the crab's breathing.It is worth mentioning that although it breathes with gills, as long as the gills are kept moist, it can absorb oxygen from the air, so it is not necessary to soak in deep water, and it is also possible to raise it in shallow water.
Crabs are omnivorous animals, eat a lot of food, and have the characteristics of scavenging, but it is best not to feed it some rotten things, so as not to get sick after eating.Usually can feed some small fish and shrimp or vegetables, it has a large appetite, so every time to feed, but also pay attention to cleaning up food residues.
