Aquatic Arts 1 Self-Cloning Marmorkreb Crayfish/Freshwater Lobster (Reproduces Without a Mate!) - 1+ Inch Juvenile Ships as a 1+ inch long juvenile (body length, minus the claws). Grows up to 4 to 5 inches with marbled color greatly intensifying as the crayfish grows larger. Some Marmorkrebs develop a blue coloration. Due to its fast reproduction and nutritious qualities as a prey item, the Marmorkreb is an excellent crayfish to cultivate as a live food item for many predatory fish that are stubborn eaters. This crayfish may TEMPORARILY change color and hide more than usual after molting, which may occur during shipping. If your crayfish is dull colored and you find a molt in the bag or in your aquarium, do not worry; this is normal and the bright color will return in 2 weeks or less. Features beautiful coloration and markings on the body that vary greatly from crayfish to crayfish! No two Marmorkrebs look quite the same! Please be advised that this crayfish will produce a great deal of clones, many of which will reach adulthood and also begin reproducing at the same rate.
