Although CPO crayfish are naturally brown-grey in color, most specimens you’ll find in the aquarium trade today are selectively bred to be bright orange. As their name suggests these dwarf crayfish are quite tiny, with a maximum size of around 2″/5 cm.

Because of their size sexing these crayfish can be a bit of a challenge, but it can be done if you know what you’re looking for. Try to get a look at the underside of your CPO crayfish: males will have an extra set of modified pleopods under their walking legs, whereas females won’t.

Because CPO crayfish aren’t nearly as aggressive as many of their “cousins” there are plenty of options when it comes to tankmates. Almost all peaceful species that are suitable for your aquarium and like the same water values will work*. Even bottom feeders and fellow dwarf crays should usually be left alone. Just avoid anything that might have an appetite for crayfish, like (dwarf) cichlids and other carnivores.
