Shrimp Crabs and Crayfish - Home. Aquatic Crabs

 

These crabs spend most, if not all of their time in water. They can and do prey on fish if they can catch them, but the smaller varieties are peaceful in a community tank, provided none of their tank mates rest on the bottom (like neon tetra). They prefer to have brackish water, although they will tolerate freshwater if a little salt is added, and are best suited in a palludarium set-up. In the wild they usually move from brackish to freshwater areas, but they march back to more brackish waters or even the sea in order release their eggs. They need an omnivorous diet of shrimp pellets, fruits, vegetables, shellfish, blood worm and other commercially available frozen foods, and will damage plants if not fed alternative greenery.


Crabs reproduce using the
