The CPO Crayfish (Cambarellus patzcuarensis) is an eye-catching fiery orange that adds a burst of color to any tank! The coloration of our crayfish is MUCH higher quality than others for sale!These do not hide during light hours like most crayfish - they are very active. However, they still do best in an aquarium with plants or tank décor that provide cover, such as a cave or tunnel.They do well in most community tanks, though they occasionally have been known to eat dwarf shrimp. A Betta may try to attack dwarf crayfish, so we can’t recommend them as tankmates.This crayfish very small sized, reaching a maximum size of 1.6 inches (4 cm). This makes it a prime candidate for small or nano aquariums, such as 5 to 10 gallon tanks.This listing is for one male young adult crayfish.
