Orange Dwarf Crayfish (Cambarellus patzcuarensis) for Sale in Canada

The Orange Dwarf Crayfish (Cambarellus patzcuarensis), often called the CPO Crayfish (Cambarellus patzcuarensis Orange), is one of the most popular freshwater invertebrates in the aquarium hobby. Its brilliant orange coloration, compact size, and active personality make it an excellent choice for planted aquariums, nano tanks, and peaceful community aquariums.
