1. Can ornamental crabs raise fish?
Ornamental crabs can raise fish. Ornamental crabs generally live at the bottom of the water and will not disturb the fish. They are not carnivorous fish and are rarely fed with crabs, so they can live in harmony with each other. Of course, it is best not to raise fish with other aquatic animals, because the environment of fish tanks is too small, and there are still some risks in polyculture. In addition, the crab will shell, and its body will become bigger after each shell, but it will be weak for a while during the shell, and it will be very troublesome once it is attacked.
Second, what should I pay attention to when raising together?
1, Choose the right species: If you want to mix crabs and fish, you should first choose the right species, not aggressive crabs and not carnivorous fish. Either crabs eat fish or fish eat crabs. In addition, don't raise some benthic fish. Living underwater is prone to conflict with crabs.
2, body shape: ornamental crabs are generally not raised too big, it doesn't matter if they are smaller, as long as they are not eaten by fish. And many common ornamental crabs are not big, such as Chili crab, spider crab, longevity crab and so on.
3. Feeding environment: In order to make ornamental crabs survive better, they should not be mixed with bare tanks, and there should be sand at the bottom of the tanks. It is best to plant some aquatic plants and provide them with a shelter. In addition, because the polyculture water body is deep, oxygen-increasing equipment is needed to keep oxygen supply.
