Info
The mud crab or tube crab is an invasive species, which is opening up ever larger habitats.
The small crayfish originally comes from fresh water, but also colonizes brackish water areas and now also various seas such as the North Sea, Baltic Sea and the Black Sea, which speaks for a high tolerance of different salinity levels.
From an aquarium point of view, however, the crayfish is of no interest.
