Ornamental crabs can always be in the water, as long as the water level is not very high, or the dissolved oxygen in the water is sufficient.This kind of animal has a high demand for oxygen, and it is easy to die if it is hypoxic.Fortunately, its structure is quite special, although it breathes with gills, as long as the gills remain moist, it can also absorb oxygen from the air.Therefore, it can be soaked in water, but do not use water to cover it, it is best to expose part of it, so that it will not be suffocated.
1. Water quality: As long as animals live in the water, they have certain requirements for water quality, and ornamental crabs are no exception.The animal prefers hard, weakly alkaline water, and if the water is too hard, it will be difficult to shed its shell and will die.In addition, we should pay attention to changing water in peacetime to keep the water quality clean and hygienic.
2. Water temperature: The ornamental crab also has certain requirements on the water temperature, which is usually kept between 15 ℃ and 25 ℃, and the highest temperature should not exceed 30 ℃.If the water temperature is low, its activities will be limited, and it will also affect its appetite, leading it not to eat, or simply enter a dormant state.
3. Dissolved oxygen: The ornamental crab must be provided with sufficient oxygen. If it is not raised in deep water, it is better. If it is raised in deep water, it is better to prepare an oxygen pump and supply it all the time, so as to ensure its breathing.
