The basics:
The Orange Dwarf Crayfish is a small crayfish which is native to volcanic lakes in the northern part of the Mexico. However, the Cambarellus patzcuarensis found in the wild are typically brown, and the Cambarellus patzcuarensis found in the aquarium trade are a bright orange, and are believed to have been selectively bred in Germany for the hobby. Crayfish are freshwater crustaceans resembling small lobsters, to which they are related. They breathe through feather-like gills and are found in bodies of water that do not freeze to the bottom; they are also mostly found in brooks and streams where there is fresh water running, and which have shelter against predators.

It has a body measuring 4–5 centimetres (1.6–2.0 in), including claws. Most specimens found in the wild are brown, sometimes with a gray or blue tint. Cambarellus patzcuarensis var. "Orange" (Mexican dwarf crayfish, sometimes Mexican dwarf orange crayfish) is an orange-coloured mutation often held in aquariums, but this form is rarely found in the wild.
