CPO Dwarf Crayfish (aka miniature crawdads) are 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 are very active and do not hide during light hours like most crayfish. They are fully aquatic and do not need land, so they can be kept in an aquarium instead of a terrarium.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 1 breeding pair, so each kit includes 1 male and 1 female crayfish.
