Mexican Dwarf Orange Crayfish (Cambarellus patzcuarensis ‘orange’)


The Mexican Dwarf Orange Crayfish (or CPO as they are sometimes abbreviated in the hobby) is a selectively bred form of a tiny, naturally-occurring dwarf species originating from crater lakes in Central Mexico. While the wild form of this crustacean is normally an unremarkable grey or brown, this form has become extremely popular in the hobby due to its vibrant orange coloration. Ideal for planted or nano aquariums, they are plant and fish safe, and unlikely to harm any tankmates including other invertebrates although individuals may spar over territories. As a scavenger, they will feed readily on most frozen or prepared sinking diets.
