Ornamental crabs can stay in the water as long as there is sufficient oxygen. This animal lives in water and has a relatively high demand for oxygen, so it is necessary to ensure sufficient dissolved oxygen. It is best to use an oxygen pump for oxygen. In addition, pay attention to changing the water to keep the water clean and hygienic. It is best to have a higher hardness in the water so that it can shed its shell more easily, and the water temperature should be controlled between 15-25°C. 1. Can ornamental crabs stay in the water all the time?

Ornamental crabs can always stay in the water, as long as the water level is not very high or the dissolved oxygen in the water is sufficient. This animal has a relatively high demand for oxygen and will easily die if it is deprived of oxygen. Fortunately, its structure is quite special. Although it breathes through its gills, it can also absorb oxygen from the air as long as its gills are kept moist. Therefore, you can soak it in water, but do not cover it with water. It is best to expose part of it so that it will not be suffocated to death. 2. What requirements do ornamental crabs have for water?

1. Water quality: Any animal that lives in water has certain requirements for water quality, and ornamental crabs are no exception. This animal prefers slightly alkaline hard water. If the water hardness is too low, it will have difficulty in shedding its shell and will die. In addition, you should pay attention to changing the water regularly to keep the water clean and hygienic.

2. Water temperature: Ornamental crabs also have certain requirements for water temperature. It should usually be kept between 15-25℃, and the maximum should not exceed 30℃. If the water temperature is relatively low, its activities will be restricted, and its appetite will also be affected, causing it to stop eating or simply enter a dormant state.

3. Dissolved oxygen: To raise ornamental crabs, you must provide sufficient oxygen. It is better if you do not raise them in deep water. If you raise them in deep water, it is best to prepare an oxygen pump to keep feeding them, so that To ensure its breathing.
